- Developers checking deployment response headers
- Worth noticing
- A finding can include a documentation URL and check date; the analyzer says it does not fetch that citation.
Field notes
The documented API accepts raw curl -sI output or JSON containing the status line and response headers, with JSON requests capped at 64 KB. Platform-specific snippets are listed for Caddy, nginx, Vercel, Netlify, and Next.js; without a recognized platform, findings return no fix. The page cautions that an empty result covers only its seven checks, not the rest of the app.
