Manifest GitHub Repositories (2026) · Open Source Tools

Sync your browser to storage you own. No middleman, no account, no tracking

The cross-browser extension framework.

SingleFile version compatible with Manifest V3

Jamf JSON schema manifests automatically generated from ProfileCreator manifests (https://github.com/ProfileCreator/ProfileManifests)

Reactive HTML attributes. No build step, signals-based, CSP-safe.

Give Grok Bot or Muse the sites you are already signed into in Chrome. A Manifest V3 extension and a local native host, no password pasted anywhere.

AI side-question layer — ask aside, stay on track.

Open-source Chrome extension with a Spotlight-style command palette, instant tab, bookmark and history search, and a customizable new tab page.

The first AI agent harness native to the browser. A browser extension that runs a full agent loop where you already work: it drives your tabs, spins up sandboxed compute (JS notebooks, WASM Linux VMs, client-side apps), and shares what it builds peer-to-peer. BYOK, no backend, no telemetry.
