Bridge for PrusaLink Autor: Tibor Djurica Potpara

Send jobs to your own PrusaLink printers from web apps you trust. Unofficial — not affiliated with Prusa Research.

Bridge for PrusaLink lets web apps you trust send G-code to your own PrusaLink
printers over your local network. The web app talks to this extension; the
extension talks to the printer. Printer addresses and credentials are stored
only in the extension and are never exposed to any web page.

How it works
- Add your printers in the extension's options: each one's LAN address and an
API key (or HTTP Digest, or none behind a trusted proxy). Host permission for
that printer is requested at add time.
- When a site first asks for access, the extension shows a consent prompt with
the browser-verified origin. You pick which printers to share and whether to
confirm each print.
- The site can then upload and start prints, read status, and cancel — but only
for printers you granted, and it never sees a URL or secret. It receives only
a name, model, and status.

Details
- Per-origin consent. No site can reach a printer without your approval, and you
can revoke access any time from the popup.
- Per-print confirmation (on by default) and a global "pause all" kill switch.
- Least privilege: no built-in printer addresses; the extension requests access
only to the exact host you enter.
- Works with plain G-code and binary .bgcode. Supports API-key and HTTP Digest.

For developers: web apps integrate a zero-dependency client library
(npm: @tibordp/prusalink-bridge) and communicate over postMessage.
