ShipCheck is an open-source deployment readiness checker. You paste a live app URL and it runs a compact pre-launch pass over the signals that usually break first, then returns a clear readiness report and a launch score.
It checks:
- Availability — confirms the app responds with a usable public HTTP status.
- HTTPS / TLS — flags plain HTTP before a demo link reaches customers or teammates.
- Response time — measures how quickly the deployed URL answers from the browser.
- Security headers — checks CSP, HSTS, frame, content-type, and referrer-policy headers.
- Health endpoints — looks for common readiness endpoints like
/healthand/readyz.
The result is a single launch score and a plain-language verdict (for example, "demo ready, not production ready") that turns a vague "is this good to ship?" into concrete, actionable findings. All checks run in the browser.
