About
snippetcheck is built by one person. It's early — the allowlist covers nine TypeScript diagnostic codes, found by hand against real packages, not a general-purpose checker (see how it works). The CLI is MIT-licensed and on GitHub.
Reports requested through this site are currently run by hand, by one person. That's deliberate while the rules are still being tuned, and it's the honest reason the false-positive rate is what it is — not a scale claim this project isn't making.
Where this is going
The hosted version runs this automatically on every release and tells you when a sample breaks, instead of you remembering to check. That's the thing being built next.
TypeScript and JavaScript are what it checks today. Other languages are the same problem with a different compiler, and which one comes next depends on who asks. If you'd want this for Python, Go, or Rust, say so — see contact below.
