• Sponsor: https://github.com/sponsors/gildesmarais

• Responsive Preact interface for demo, sign-in, conversion, and result flows.
• Automatic source discovery with token-scoped permissions.
• Signed public feed URLs that work in standard RSS readers.
• Built-in URL validation, scoped feed access controls, and HMAC-protected tokens.

• Backend: Ruby + Roda, backed by the html2rss gem for extraction.
• Frontend: Preact app built with Vite into frontend/dist and served at /.
• Distribution: Docker Compose by default.

For detailed architecture and internal rules, see docs/README.md.

The published image already includes a sample config/feeds.yml, so you can try the app without creating or mounting one first.

docker run --rm \
  -p 4000:4000 \
  -e RACK_ENV=production \
  -e HTML2RSS_SECRET_KEY=$(openssl rand -hex 32) \
  html2rss/web

Then open:

• http://localhost:4000/ for the web UI
• http://localhost:4000/microsoft.com/azure-products.rss for a built-in Azure updates feed

This trial run is intentionally minimal. Use Docker Compose for Browserless, auto-updates, or local feed overrides.

1. Generate a key: openssl rand -hex 32.
2. Export HTML2RSS_SECRET_KEY, HEALTH_CHECK_TOKEN, and BROWSERLESS_IO_API_TOKEN in your shell or .env.
3. Start: docker-compose up.

UI + API run on http://localhost:4000. The app exits if the secret key is missing.

Use the repository's Dev Container for all local development and tests. Running the app directly on the host is not supported.
