grepular/parsemail-renderer repository overview

⁠parsemail-renderer

An HTTP sidecar that renders a blob of HTML to PNG and PDF, light and dark, with headless Chromium via Playwright. It exists to serve ParseMail⁠, so the HTML it renders is email from strangers, and every input is treated as hostile. Remote content is blocked by default. When a caller opts in, every address a hostname resolves to must be publicly routable, and redirects are re-checked hop by hop.

It is a Debian image (Chromium can't run on scratch), kept separate from ParseMail for its own patch cadence, memory limit and read-only filesystem. It is rebuilt nightly and published only when its contents change; images are signed with cosign. Pin the immutable tag X.Y.Z_<hash>; X.Y.Z is republished when a dependency is patched, and X.Y and latest move.
