🧼 Scrubbed

Automated checks — 5/7 passed

Every listing gets the same checks, run by machine. We publish the ones it failed as well as the ones it passed.

✓ Secrets removed, nothing left needing reviewThe scrubber found no credentials or personal data it couldn't safely handle.
✗ Builds from a clean checkoutNot checked yet.
✓ No placeholder or elided codeNo files containing “… rest of the code” style markers, the sign that a file doesn't hold what it appears to.
✓ Not an untouched starter templateThe project isn't a generator's output with the README still in place.
✓ Substantially implementedFew or no files that are nothing but “TODO: implement”.
✓ No restrictive or conflicting licence termsNothing in the code claims terms that would stop a buyer using it.
✗ Repository history verifiedThe seller proved control of the original repository, and its commit history was read directly from GitHub.

✨ Cindy's Take

Curious

A competitive Python coding-duel app: Next.js frontend (PyBattle), a separate API backend and a realtime service, plus a Supabase schema for users/matches/ELO. There's a deployed Vercel URL, so at least the frontend shell is live.

For $200 the appealing part is structural: someone already made the architectural decisions you'd otherwise spend a weekend on — split API vs. realtime services, a Supabase schema file for the ELO/leaderboard data model, and a deployed Next.js front end. That skeleton plus a clear, genuinely fun product thesis (1v1 LeetCode with ranked ELO) is a real head start on a blank repo. Before buying, check the three things that make or break this: whether the realtime service actually pairs two players end-to-end, whether there's any sandboxed Python execution at all (the stack is TypeScript/JS, so judging may be unbuilt or outsourced), and how many problems exist in the content set. Readiness of 34 says expect scaffolding and partial flows, not a working game — price it as a starting point, and you're paying less than a few hours of your own time for the setup.
