Camo is a lightweight Node.js HTTP proxy that serves insecure (HTTP) images over HTTPS, eliminating mixed-content warnings on secure webpages. It authenticates request URLs via HMAC, allowing admins to cache-bust or block content, and supports whitelisting by MIME type. Originally built by atmos for GitHub comments, it's now archived but continues to be used and forked (e.g., camo.cr).
Features
- Proxies HTTP assets through HTTPS to prevent mixed-content
- HMAC-signed URLs enable cache invalidation/control
- Whitelists image MIME types for security
- Built in Node.js; easy to deploy via Docker or Procfile
- Used by diaspora* and GitHub to secure embedded images
- Repository archived (read‑only since April 2021)
