Introducing OpenLoom

Screen recording tools are everywhere, but they all want the same thing: your data on their servers, a monthly subscription, and eventually — lock-in.

OpenLoom is different. It's a fully open-source screen recorder that stores videos on your own Supabase project. No central server. No tracking. No subscription required.

Why We Built This

As developers, we record a lot:

  • Bug reproductions for teammates
  • Quick demos for PRs
  • Async standups
  • Documentation walkthroughs

But existing tools felt wrong:

  • Loom is polished but expensive, and your videos live on their servers
  • OBS is powerful but overkill for a 30-second bug demo
  • Native OS recording gives you files to upload somewhere else

We wanted the convenience of Loom with the ownership of self-hosting.

How It Works

Chrome Extension → Your Supabase Project → Web Viewer
  1. Click the extension — pick a tab or window to record
  2. Record — with optional camera PiP and microphone
  3. Upload — video goes directly to your Supabase storage bucket
  4. Share — get an instant link, copied to clipboard

The web viewer fetches directly from your Supabase. There's no OpenLoom server in between.

Features

  • Screen + Camera PiP — Drag to reposition, resize the camera overlay
  • Microphone + system audio — Live audio meter, mute toggle
  • HD recording — Up to 1080p with VP9/WebM encoding
  • Password protection — AES-256-GCM encryption for sensitive videos
  • One-click setup — Paste your Supabase connection string and the extension provisions everything

Tech Stack

| Component | Stack | |-----------|-------| | Extension | TypeScript, React 19, Tailwind CSS 4, Vite | | Recording | getDisplayMedia, MediaRecorder (VP9/Opus) | | Web Viewer | Next.js 16, static export, GitHub Pages | | Backend | Supabase (Storage, PostgreSQL, Edge Functions) |

Get Started

  1. Download the extension from the Releases page
  2. Load it unpacked in Chrome
  3. Paste your Supabase connection string
  4. Record your first video

The extension handles provisioning automatically — storage bucket, database tables, edge functions.

What's Next

We're actively building:

  • Firefox extension
  • Desktop app (Electron) for full-screen capture
  • Team features (shared Supabase projects)
  • Embeddable player widget
