What is Docker Compose Image Version Checker?

A privacy-first browser tool that reads your Compose file locally, extracts public container image references, and checks public sources for newer stable tags.

How it works

  1. Paste or drop a compose.yaml / docker-compose.yml.
  2. Images are parsed in your browser (services → image only).
  3. Public tags are fetched from supported registries or CORS-safe public fallbacks.
  4. You pick compatible updates and generate an updated Compose file locally.

Privacy

  • YAML parsing happens locally.
  • The complete Compose file is never uploaded.
  • Only public repository/tag lookups leave the browser.
  • No signup, no analytics by default, no credentials.

Supported registries

  • Quay.io — public tag API from the browser.
  • Docker Hub — Hub API is often CORS-blocked; fallbacks use official-images and public GitHub tags (no CORS proxy).
  • GHCR and private registries are unsupported without credentials.

Patch vs minor vs major

Compatible updates stay on the same major and image variant (for example alpine). Major bumps are shown for review and are not auto-selected.

Limitations

  • “Compatible” is version-family matching — not application upgrade safety.
  • CORS, auth, or rate limits may block some lookups.
  • Interpolated images without a clear default need manual review.
