Honest comparison · Lifetime deal tracker
DealKeep vs Stackerr
Stackerr is the closest thing to a direct DealKeep competitor: a dedicated lifetime-deal tracker with a Chrome extension, spend reports and refund reminders. The differences are in depth, in what each does about failure, and in how you pay.
The short version
Both are built for lifetime-deal buyers and both do the basics: a one-click Chrome extension, spend tracking, and a reminder before a refund window closes. Stackerr leans into reporting and gamification — a Buying Score, badges, a leaderboard, monthly and lifetime spend views — and is priced as a $10/month subscription above its free tier. DealKeep leans into prevention — duplicate detection by job, Founder Track warnings from a verified failure database, AI search over your stack, an MCP server for Claude and ChatGPT — and is priced one-time. If you enjoy scoring your buying habits and are happy with a subscription, Stackerr is a good fit. If you want the tool to stop the next bad purchase and never bill you again, DealKeep.
Pick DealKeep if: You want duplicate and failure prevention, AI search, agent access, and one-time pricing for a lifetime-deal stack.
Pick Stackerr if: You want spend reports, a buying score and badges, and don't mind a monthly subscription for unlimited tracking.

Frequently asked questions
Which is cheaper, DealKeep or Stackerr?
Stackerr's free tier covers more tools (30 vs 10). Past that, Stackerr Pro is $10/month; DealKeep Starter is $97 once and Pro is $227 once. Starter pays for itself against Stackerr Pro in under 10 months, and there is nothing to cancel afterwards.
Does Stackerr detect duplicate tools?
It isn't a listed feature on Stackerr's site as of the date on this page. DealKeep flags tools in your stack that do the same job, and checks a prospective purchase against what you already own.
Both track failed LTDs — what's the difference?
Stackerr lets you mark your own LTDs as failed and reports which platforms list failing products. DealKeep's Founder Track checks the tools you own against a community-verified failure database — the same data behind the public LTD Mortality Report — and warns you when one of yours appears in it or shows risk signals.
Can I import my AppSumo purchases into both?
Both offer a Chrome extension that adds a deal with one click. DealKeep additionally accepts CSV and forwarded receipt emails, which covers marketplaces the extension doesn't touch.
DealKeep is free for up to 10 tools and offers a 7-day trial of everything else, no card. Start free.
