Paste a chunk of your script. We run a lightweight, in-browser heuristic for the six signals that make a buyer comfortable — error handling, secrets, docs, versioning, input checks, ownership — and show you where the gaps are. Your code never leaves this page.
What we look for
None of these change what your script does. They change whether a stranger believes it's safe to run. That belief is what you're actually selling.
Does it fail with a clear message, or crash silently on the buyer's edge case?
Keys and tokens baked into the file are an instant red flag — and a real risk.
A header comment and install steps are the difference between a sale and a refund.
A version marker signals it's maintained, not abandoned the day after purchase.
Guards against the nulls and wrong file types that make "it doesn't work" tickets.
A clear license tells buyers what they're allowed to do — and that you're legit.
From score to sellable
This tool is deliberately simple — a teaser, not an audit. The Certified Seller Sprint does the real security scan, adds the error handling and docs, writes the listing, and stands behind it with a 90-day badge.
Want the full checklist + a slot?
We'll email the full version of these signals and hold a sprint slot. Stored locally in this demo.
