General
Omni is a free, open-source Android browser built on Mozilla’s GeckoView engine (the one in Firefox) with a 100% native Jetpack Compose interface. It combines strong privacy defaults — ad/tracker blocking, Tor, a WireGuard VPN, an encrypted vault — with power tools like a stream sniffer, native video player and Firefox extension support.
Yes. The app is licensed GPLv3 and the full source is on GitHub. Note that the names “Omni Browser” and “RebelRoot” are trademarks — if you fork and distribute, you must rebrand (see the trademark policy).
No. There are no analytics SDKs, no crash reporters, no accounts and no telemetry. Your history, bookmarks and vault never leave your device. The only network calls Omni makes are the ones you initiate (loading pages, updating filter lists, downloading FFmpeg on demand).
Omni is marked experimental. It’s actively developed and many people use it daily, but expect rough edges and breaking changes between releases. Keep your important data backed up and report issues.
Features
Yes — real .xpi add-ons from addons.mozilla.org, because Omni runs the actual Gecko engine. Three are bundled: Media Grabber, AI Blocker and Universal Copy. See Extensions.
Two cooperating paths: the Media Grabber extension watches network requests and MSE/blob playback, and the native MediaInterceptor looks for HLS/DASH manifests. Detected streams can be played in the native player or downloaded. See Media Hub.
Not currently. Earlier builds used on-device ML Kit, but that was removed for FOSS compliance. Translation now uses a free online endpoint, so translated text leaves your device. Don’t translate sensitive content.
The vault stores sensitive pages, images and notes behind biometric/PIN. The database is encrypted with SQLCipher (AES-256) and files with AES-256-GCM via the Android Keystore. See Privacy & Security.
Licensing & distribution
The code is GPLv3, so yes — but you must rename and rebrand. “Omni Browser” and “RebelRoot” are trademarks, and GPLv3 §7(b) requires attribution (repo link, in-app credit, preserved copyright headers). Read License.
Only from the official GitHub Releases or F-Droid. Avoid third-party APK mirrors. See Installation.
