I built a free production-readiness scanner for developers — tells you if your app is actually ready to ship

I got tired of deploying apps and finding out later they had embarrassing issues — missing security headers, exposed config files, no HTTPS redirects, leaking server info in headers. So I built DeploySafe: paste your URL, get a score in seconds. It checks 15+ things across three categories: - 🔐 Security — CSP, HSTS, X-Frame-Options, exposed .env/.git files, cookie flags, CORS misconfig, server header leakage - ⚡ Performance — TTFB, compression, caching headers - 🏗️ Infrastructure — SSL/TLS validity, HTTP→HTTPS redirect, DNS config No signup. No install. Just a URL. → https://deploy-safe.com Built with React + NestJS, deployed on Vercel + Railway. Took about a week of evenings. Feedback welcome — especially if you find a check that gives a false positive or misses something obvious. submitted by /u/Narrow-Extent4960 [link] [comments]
