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 through a server-side inspection API.
- Security headers, checks CSP, HSTS, frame, content-type, and referrer-policy headers.
- Health endpoints, looks for common readiness endpoints like
/healthand/readyz.
The report separates confirmed results from checks it could not inspect. Launch Score summarizes the verified signals; Inspection Confidence shows how much the tool could actually check. URL inspection runs through a server-side API, with results displayed in the browser.
These checks can identify deployment issues. They do not establish production readiness, application correctness, or security on their own.
