Best AppSumo Deals (September 2026): Re-Verified, 3 Picks Sold Out

Affiliate disclosure: some links in this article are partner links. If you start a paid plan through them, imisofts may earn a commission at no extra cost to you. We only recommend tools we actually use to run client campaigns.

Quick answer: AppSumo lifetime deals are still the cheapest way to assemble the supporting layer of a software stack in 2026, and we still buy them. But when we re-opened every listing on this page on September 5, 2026, three of the five picks we had verified live on August 9 were sold out: Letterly, Poppy AI and Cleanlist AI. That is three losses in 27 days, on the three vendors with the most active founder feeds on the list. In the same month AppSumo quietly split Plus into three tiers, including a 12 dollar monthly plan that changes the arithmetic we published. Below is the corrected version: the two picks that survived, three replacements re-verified today with their entry tier limits, the new Plus math, and the three buying filters that still hold.

What changed since August 9, including two things we got wrong

We refreshed this page on August 9, 2026 with five live picks. Twenty seven days later we re-opened every listing. Here is what moved, including our own errors, because a roundup that never corrects itself is not a roundup, it is an advertisement.

• Letterly, Poppy AI and Cleanlist AI are sold out. All three listings now show a Sold out label and a notify me button. Three of our five August picks, gone in under a month. Only LeadRocks and Stackby remain buyable.
• We told you that founder activity predicts nothing about deal availability. It may predict the opposite, and we now have four data points. FlexiFunnels in August, and Poppy AI, Letterly and Cleanlist AI in September, were the four most active founder feeds we have listed this year. All four closed their campaigns. The quiet vendor, LeadRocks, whose last founder post is from 2023, is still selling.
• AppSumo Plus is no longer one 99 dollar product. The Plus page now shows three plans: Annual at 99 dollars a year, Monthly at 12 dollars a month, and Pro at 199 dollars a year. The monthly plan does not include the 100 dollars in coupons. The Pro plan doubles the We Got Your Back window to two years. The old standalone Plus listing, the one that carried a 3.88 rating and the worst one taco share on this page, now redirects to the homepage. More on the new math below.
• We described the Plus coupons as a limited time perk. On the current Plus page that label is gone and the coupons are described as included on annual plans. Our August wording is out of date.
• LeadRocks drifted down, slightly. 4.47 from 371 reviews today against 4.49 from 369 in August, and the one taco share rose from 7.6 to 8.1 percent. Price, badge and refund window are unchanged.
• Stackby is unchanged on every number we published, and its deal terms now carry a line we had not quoted before: optional add ons are only available while the deal is available on the store. The founder's February post says the same add ons move to annual recurring pricing after the campaign.

Two of five survived. That is a worse survival rate than the August cycle, when five of six made it, and a similar one to July, when three of seven vanished in eighteen days. The pattern across all three cycles is the same, and it is the opposite of what every checklist assumes. We explain it below.

What AppSumo is and why the deals are cheap

AppSumo is the largest marketplace for software lifetime deals, now in its sixteenth year according to its own logo. Early stage software companies list a plan at a steep one time price in exchange for a burst of paying users, cash, and feedback. You get lifetime access to the plan you bought. The vendor buys growth. AppSumo takes a cut.

That trade explains the upside and the risk in one sentence. The discount is real because the vendor is buying distribution, not running a charity, and some of those vendors will pivot, be acquired, or close. AppSumo reduces the risk with buyer reviews scored out of five tacos, an AppSumo Select badge for products its team vets directly, a separate AppSumo Launchpad badge for products chosen on potential rather than track record, and a refund guarantee. That last one is where the trouble starts.

The 60 day guarantee is not universal: three listings prove it

Practically every article about AppSumo, including ours in July, tells you the same comforting thing: everything is covered by a 60 day money back guarantee, so treat it as a free trial. That is the single most repeated claim in the category and it has real exceptions sitting inside our own short list.

• Stackby: 30 days, not 60. Verified on the listing and again in its pricing table on August 9, 2026, and re-verified September 5. If you buy a database platform expecting two months to migrate real data into it, you have one.
• FlexiFunnels: the We Got Your Back guarantee applied to Plus members only. Its listing carried the AppSumo Launchpad badge, not Select, and the fine print read "Plus members are covered by our We Got Your Back guarantee". Launchpad products are, in AppSumo's own words, chosen for their potential and innovation. The protection tier follows the badge.
• AppSumo Plus itself: non refundable, on all three plans. The membership that sells you extra purchase protection carries none of its own. The Plus pricing page states that all plans are subscriptions and are not refundable, and each plan card repeats it.

None of this is hidden. All three sit in plain text on the product pages. It is simply never in the summary, because the summary is written by people who did not open the pages. Read the refund line on the specific listing, every time, before you buy. It takes four seconds and it is the only line on the page that decides whether a mistake costs you money.

The sticker price is not the price: what 109 dollars actually buys

The second thing roundups flatten is the tier table. A lifetime deal is a plan, not a product, and the plan you get at the entry tier is often missing the exact feature the headline sold you. Stackby is the clearest example on the current roster, and we can show the arithmetic because Stackby publishes every add on price.

Stackby is listed as spreadsheet style databases with powerful automations, and in July its founder announced the platform's evolution into an AI native app builder with new interfaces. Now open the tier table. At the 109 dollar one code tier you get 1 user, 20 stacks, 5,000 rows per stack, 4GB of attachments and 100 conversational AI credits. You also get zero internal automations per month, zero apps or interfaces per stack, and zero API automation runs. Those numbers are literally 0, and they stay 0 at the two, three and four code tiers.

The automations are a separate one time add on, priced from 149 dollars for 3,000 runs a month up to 699 dollars for 30,000. Powerups cost 449 dollars. The Apps Marketplace, which is what unlocks the interfaces, costs 499 dollars. Sync across databases is 349 dollars and the CRM package is 399 dollars. So:

• To get the automations in the product's own one line description, the real entry price is 109 plus 149, or 258 dollars, about 2.4 times the sticker.
• To get the apps and interfaces the founder's July launch post is built around, it is 109 plus 499, or 608 dollars, about 5.6 times the sticker.
• Buying the headline sticker plus Powerups, Apps Marketplace, Sync and CRM comes to 1,805 dollars, which is more than sixteen times the advertised 109.

There is a second detail worth catching, and it is a straight comparison of Stackby's own posts. In a founder update dated February 16, 2026, the Powerups add on was 399 dollars and the Apps Marketplace was 399 dollars. Today the same two add ons are listed at 449 and 499. Lifetime pricing on the base plan does not stop the add ons around it from rising. None of this makes Stackby a bad buy. It makes 109 dollars the wrong number to compare against an Airtable subscription. Compare 258, or 608, depending on what you actually came for.

The same discipline applies elsewhere on the list. LeadRocks at 79 dollars gives 5,000 contact credits a month but zero email verification credits and zero outreach seats, which begin at the two code, 158 dollar tier. Cleanlist AI at 79 dollars, while it was on sale, gave 250 one time credits plus 150 a month, with a cap of 100 contacts per list. ZeroRank AI at 69 dollars, one of our replacements below, gives unlimited prompts but zero article generations and zero content optimizations at the entry tier, both of which start at tier 3. The same zero at the bottom of the table pattern, on a product launched three months ago. FlexiFunnels at 49 dollars allowed 2,500 monthly visits, one custom domain and a 2 percent transaction fee. Open the table. Always.

Read the one taco share, not the star average

Every buying guide tells you to filter by rating. That advice is nearly useless as normally stated, because a rating average compresses the exact information you need. What you want to know is not the mean. It is how often this product produces a furious buyer.

AppSumo publishes the full distribution on every listing, broken into five, four, three, two and one taco counts. Almost nobody reads it. Here is the current roster, live picks and sold out picks together, with the share of reviewers who gave the lowest possible score, all counted on September 5, 2026:

• ZeroRank AI: 4.93 average, 0 one taco reviews out of 42, or 0.0 percent. Live. Too few reviews to lean on yet.
• Respona: 5.00 average, 0 out of 12. Live. Twelve reviews is not a distribution, it is a start.
• TruConversion: 4.91 average, 6 out of 1,547, or 0.4 percent. Live, and the only product on this page with a review base large enough to make the number mean something.
• Letterly: 4.70 average, 5 out of 361, or 1.4 percent. Sold out.
• Poppy AI: 4.88 average, 3 out of 159, or 1.9 percent. Sold out.
• Stackby: 4.66 average, 3 out of 145, or 2.1 percent. Live.
• Cleanlist AI: 4.76 average, 3 out of 113, or 2.7 percent. Sold out.
• LeadRocks: 4.47 average, 30 out of 371, or 8.1 percent. Live.

Now compare TruConversion and LeadRocks. They are 0.44 apart on the star average. On the measure that matters they are twenty times apart, because one in every twelve LeadRocks buyers rated it one taco versus one in 258 for TruConversion. In August the extreme case was AppSumo Plus, a 3.88 average hiding an 18.1 percent one taco share. That listing no longer exists as a product page, so the distribution is no longer published anywhere we can find, and the new Plus page carries curated testimonials instead. A high average with a fat one taco tail is not a good product with a few cranks. It is a product that works brilliantly for most people and fails badly for a specific minority, and the only question that matters is whether you are in that minority. Read the one taco reviews before you read anything else. They tell you who this is not for.

The 12 month filter is unusable, so replace it with one you can check

Our July checklist said to buy tools that had been on the market twelve months or more. Every roundup says a version of this. We now think you cannot apply it from AppSumo's data, and we can show why.

AppSumo displays a founding date on each listing, and it is vendor reported. LeadRocks shows January 1, 2020. Cleanlist AI shows January 1, 2026. A January 1 date is a placeholder, not a fact. Worse, Poppy AI's page currently displays two different founding dates in two different blocks of the same page, May 11, 2024 near the top and April 1, 2024 lower down, along with two different company stages, Expansion in one block and Growth in the other. When a field contradicts itself within one page, it cannot carry a buying rule.

There is a far better signal on the same page and it is timestamped: the founder update feed. Every post carries a date, and the dates cannot be back written by a form field. Applied to this roster it is brutally informative, and the first thing it does is convict us. Note, too, what the list does not do: the three most recently active vendors as of August are the three that sold out.

• Poppy AI: last founder post August 4, 2026. Sold out by September 5.
• Respona: July 12, 2026. A relaunch post, with a concrete change to the deal terms.
• Stackby: July 13, 2026. A substantial launch post.
• ZeroRank AI: June 30, 2026. A long changelog, the fourth post since a May 22 launch.
• Letterly: May 20, 2026. Sold out by September 5.
• Cleanlist AI: April 28, 2026. Sold out by September 5.
• TruConversion: March 16, 2026. A relaunch post; the previous one is from September 2025.
• LeadRocks: September 5, 2023. Three years ago to the day we re-checked it.

Our own headline lead generation pick has not posted a founder update in exactly three years, and our own checklist says that eight months of silence means the team has moved on. We recommended it anyway, three times, because we checked the rating and the price and never checked the feed. LeadRocks is still live, still AppSumo Select, still sells a working 100 million record database, and its product may be perfectly well maintained behind a quiet AppSumo page. But the honest statement is that we cannot see evidence of it here, and neither can you, and that is exactly the thing our checklist was supposed to catch.

So the revised filters are: rating distribution over rating average, dated founder activity over claimed founding date, and the refund line on the specific listing over the platform wide promise. All three are checkable in under a minute, and all three are things the vendor cannot simply assert.

The AppSumo deals we would still buy, verified September 5, 2026

Prices below are the entry tier one time price, confirmed live today. Everything here carries the tier limits that actually apply, not just the headline. Two picks survived from August. Three are new, chosen for the same buyer this page has always been written for: an agency or a small team that needs pipeline, traffic and internal tooling for a few hundred dollars, once.

• LeadRocks, 79 dollars (against a 1,740 dollar reference price). 4.47 from 371 reviews, AppSumo Select, 60 day refund. A B2B contact database with 100 million plus records covering emails, phone numbers and LinkedIn profiles, plus a Chrome extension, CSV and CRM export, and LinkedIn URL enrichment. The 79 dollar tier gives 5,000 contact credits a month with zero verification credits and zero outreach seats, both of which start at 158 dollars. Still the best raw prospecting value at this price, and still the survivor: the quietest vendor on the list is the one that keeps selling. Read the two caveats above it, the 8.1 percent one taco share and the 2023 founder feed. Buy it as a list source, verify everything before you send, and do not build a business process on top of it.
• Stackby, 109 dollars (list 160 dollars). 4.66 from 145 reviews, AppSumo Select, 30 day refund window. Spreadsheet style databases with 1,000 plus templates, eight views, and an Airtable importer. Genuinely useful for client trackers, content calendars and lead pipelines. Read the sticker price section above before you buy: automations and interfaces are paid add ons, the honest comparison price is 258 dollars or more, and the deal terms say the one time add ons are only sold while the deal is live.
• TruConversion, 79 dollars (list 499 dollars). New. 4.91 from 1,547 reviews, AppSumo Select, 60 day refund, and the lowest one taco share on this page at 0.4 percent. Funnel tracking, heatmaps, session recordings, form analytics and on page surveys in one dashboard, positioned as a Hotjar alternative. The entry tier is 1 user, 3 domains, 110,000 monthly page views and 5 SitePulse AI reports; 3 users and 5 domains start at 139 dollars. No codes, tiers only, and you can upgrade while the deal is live but only downgrade within 60 days. The listing showed the deal ending in about 12 days when we checked, so treat it as time boxed. This is the one we would buy first for any client site that has a form on it.
• ZeroRank AI, 69 dollars (list 1,196 dollars). New. 4.93 from 42 reviews, AppSumo Select, 60 day refund. Tracks whether your brand is mentioned and cited in ChatGPT, Perplexity, Gemini, Google AI Overviews and AI Mode, Grok, Copilot and nine more models, then turns the gaps into on page, off page and technical recommendations. This is the category we work in, and it is the first lifetime deal we have seen that does the job properly. Read the table: the entry tier has unlimited prompts but 180 answer credits a month, 5 prompt research runs, one workspace, and zero article generations and zero content optimizations, which begin at tier 3 for 329 dollars. Frontier models such as Claude and GPT-5 draw more than one credit per run, per the founder's June 30 post. The deal terms also restrict it to brand new ZeroRank users, so a past trial disqualifies you. The company was founded in July 2025, so this is a young product with a fast, well documented changelog, exactly the profile that sold out three times on this page. If it clears your filters, do not wait.
• Respona, 79 dollars (list 798 dollars). New. 5.00 from 12 reviews, AppSumo Select, 60 day refund. Backlink outreach in one place: prospect search filtered by SEO metrics, contact discovery, personalised sequences and follow ups from your own inbox, with Ahrefs and Semrush integrations. The entry tier gives 2 email accounts, 1,000 credits a month plus a 5,000 credit one time bonus, and 30,000 active contacts, with unlimited users and workspaces on every tier. The founder's July 12 post says the recurring monthly credits are new in this relaunch because the first campaign was one time credits only, which is the right fix. Twelve reviews is not enough to read a distribution from, and the terms restrict it to brand new Respona users. Buy it if you already run link outreach by hand. Do not buy it as your first cold email tool; that is what our cold email service and the dedicated sending platforms are for.

The total for all five live picks is 415 dollars, down from 635 in August, because the three that sold out included the 279 dollar Poppy AI. Keep that number; it matters for the Plus arithmetic below.

Why the healthiest vendors on our list are the ones that sold out

In August we lost FlexiFunnels, which was by every activity measure the most alive vendor on the page, and we wrote that vendor health and deal availability are two separate risks. We now have three more data points and they all point the same way.

Poppy AI, Letterly and Cleanlist AI were, on August 9, the three picks with the most recent founder posts, the highest ratings with real review volume, and in Poppy's case a product event scheduled for the following day. All three now read Sold out with a notify me button. Poppy's page even carried a bring your own key launch for its upper tiers on June 15, a webinar on June 25, a feature day on July 2 and another on August 10. That is not a vendor fading. That is a vendor that got what it came for and closed the campaign.

Meanwhile LeadRocks, whose founder feed stopped on September 5, 2023, is still on sale at the same price with the same badge, three years to the day later.

That is the distinction almost every lifetime deal guide blurs, and it has now cost us four picks in two months: an active roadmap predicts that the product will still exist in three years. It predicts nothing about whether the deal will still be on sale next month, and across our own list it has predicted the opposite. A vendor shipping hard is buying distribution from AppSumo; once the burst of users and cash has done its job, the discount ends. A vendor that has gone quiet has less reason to switch it off. Use the founder feed to judge whether the software survives. Use nothing at all to time the purchase, because there is nothing to use. If a deal clears your filters today, the refund window, where you actually get one, is the trial. Waiting is the expensive move, and this page has now demonstrated it four times.

AppSumo Plus now has three plans, and the math changed

In August AppSumo Plus was one product at 99 dollars a year. On September 5, 2026 the Plus page shows three plans, all subscriptions, all non refundable:

• Annual, 99 dollars a year. 10 percent off every order, 100 dollars in coupons delivered as 25 dollars every 90 days, early and extended access, free License Tier 1 of KingSumo and SendFox, VIP support, and the We Got Your Back guarantee for one year: if an AppSumo Select tool closes within a year of purchase, Plus members get 100 percent back in credits, against 50 percent for everyone else.
• Monthly, 12 dollars a month, cancel anytime. Everything above except the coupons. The comparison table marks the 100 dollars in coupons as not included.
• Pro, 199 dollars a year. Everything in Annual, with the We Got Your Back window extended to two years.

One caution before the arithmetic. The page source we loaded carried an experiment flag reading plus-multi-tier: treatment, which means AppSumo may still be testing the three plan layout and some visitors may see the old single plan. Check what your own account is offered before you rely on the numbers below.

Now the math, which is more interesting than it was in August, because the monthly plan breaks the old case wide open.

• The annual plan still does not pay for itself on the discount alone unless you spend 990 dollars a year. If you bought every live pick on this page, LeadRocks, Stackby, TruConversion, ZeroRank AI and Respona, you would spend 415 dollars and your 10 percent would come to 41.50 dollars, which is 57.50 dollars less than the membership costs. Only the coupons close that gap, and the first three of them arrive across nine months.
• The monthly plan is the one to run the numbers on. Join for 12 dollars in the month you buy a stack, take 10 percent off every order in that month, and cancel. On our 415 dollar list that is 41.50 dollars off for 12 dollars in, a net saving of 29.50 dollars with no annual commitment and no waiting for coupons. The break even is 120 dollars of spend in a single month, which is less than two entry tier deals. AppSumo's own Plus calculator, which defaults to 1,350 dollars of annual spend, does not model this case.
• The Pro plan only makes sense as insurance. The extra 100 dollars a year buys a second year of 100 percent credit protection on Select tools that close. On a 415 dollar stack, that is paying 100 dollars to insure the difference between 50 and 100 percent recovery on at most 415 dollars, and only for closures in year two. Skip it unless your annual spend runs into the thousands.

The old advice on this page was to join Plus for the quarter you assemble a stack and cancel before renewal. The monthly plan is that advice turned into a product, at 12 dollars instead of 99. Use it that way. What has not changed: every plan is non refundable, the coupon schedule still needs nine months of membership to pay out in full, and the old Plus product listing with its 3.88 rating and 18.1 percent one taco share has been removed from the store, so the only reviews you will now find on the Plus page are the ones AppSumo chose to display.

The honest downsides nobody puts in the headline

We earn a commission if you buy through our links, so treat this section as the proof that we want you buying well rather than often.

• The deal you are reading about may already be gone. Three of five picks sold out in the 27 days between our last two checks. Every price on this page carries the date it was verified for that reason.
• Lifetime means the product's lifetime, not yours. If the vendor closes, your deal closes with it. This is the single biggest risk and no checklist removes it.
• The refund window varies and it is on the listing, not the platform. We published the wrong window for one of our own picks in July. Check yours.
• Entry tiers are where the metering lives. Zero automations, zero verification credits, zero article generations, one device license, 100 contacts per list. The tier table is the product.
• Add on prices move even when the plan is lifetime. Two of Stackby's rose between February and August 2026.
• Support is rarely subscription grade. You paid once, and some vendors quietly prioritise recurring subscribers in the queue.
• These are not category leaders. A 79 dollar contact database is not ZoomInfo and a 109 dollar spreadsheet database is not a CRM. For the systems that directly produce revenue, the subscription is sometimes the correct answer.

Where lifetime deals belong in a real stack

The disciplined way to use AppSumo is to cover the supporting layer of the business for a few hundred dollars, once, and keep recurring spend for the systems that directly generate revenue. Scheduling, forms, documents, internal databases, dictation and content tooling are ideal lifetime deal territory. AppSumo's own permanent products fit here too: TidyCal, SendFox, BreezeDoc, FormRobin and KingSumo carry the lowest survival risk on the platform for the obvious reason that AppSumo is not going to shut down its own software. If you want to weigh AppSumo against the other lifetime deal marketplaces before you commit, our guide to the best lifetime SaaS deals compares it with DealMirror, Dealify and SaaS Mantra.

The pipeline is the part worth doing properly. Finding the right prospects, reaching them, and booking the call is where a 79 dollar database with no verification credits stops being a bargain and starts being a bottleneck. That is the part we build and run for clients every day, with done for you B2B lead generation and cold email campaigns that sit on top of whatever stack you assemble, lifetime deals included, and AI automation to keep the follow up from depending on anyone remembering. Buy the cheap database. Spend what you saved on the system that converts it.

Bottom line: AppSumo in 2026 still rewards disciplined buyers, but the discipline has to be sharper than the standard checklist. Check the refund line on the listing, open the tier table, read the one taco share instead of the average, and look at the date on the last founder post. Four checks, under a minute, and they would have caught every mistake we have corrected on this page since July. Then add a fifth that no check can help with: if it clears the filters, buy it this week, because on this page the good ones are the ones that disappear.
