BestBlurays Companion

A browser extension that injects BestBlurays release info directly into Letterboxd film pages — best available format, video/audio picks, English-friendly release, and links back here and to Blu-ray.com. No account, no tracking, one content script.

Install

Chrome and Firefox versions are identical — pick whichever matches your browser. The userscript is a single-file port for Safari and for anyone who prefers not to install a full extension.

Safari

Apple does not publish a native version of this extension on the Mac App Store. The easiest install path is the userscript route:

1. Install the Userscripts app (free, by Justin Wasack) from the Mac App Store.
2. Open it, grant it permission to run on Letterboxd, and pick a folder to store scripts.
3. Click bestblurays-companion.user.js — Userscripts will offer to install it.
4. Visit any Letterboxd film page. The panel should appear in the sidebar.

Userscript (any browser)

Works in Chrome, Firefox, Edge, and Safari. Useful for sharing a single link (e.g. on Discord) without going through a store.

1. Install a userscript manager: ViolentMonkey (open source, all browsers) or TamperMonkey.
2. Click bestblurays-companion.user.js. The userscript manager intercepts the .user.js extension and shows an install prompt.
3. Confirm install, then visit any Letterboxd film page.

What it does

• Runs only on Letterboxd pages.
• Queries BestBlurays and show best releases information in a panel.
• If the film isn't catalogued yet, it'll still show a handy Blu-ray.com link
• Does not send any data to third parties. No analytics, no account needed.
