Desktop-Grade Performance in Your Pocket
Omni Browser is a state-of-the-art mobile browser developed by the RebelRoot collective. Powered by Mozilla's GeckoView engine, it provides built-in ad blocking, native Firefox extensions, offline ML translation, and hardware-secured sandbox vault mechanics.
Explore the advanced offline tools, privacy containers, and visual customizers packed inside Omni.
Safe Locker (Vault)
Omni features a dedicated, hardware-secured directory sandbox that isolates and encrypts private files away from standard Android shared storage.
- 🔒 **Hardware Encrypted:** Secured with AES-256 GCM (`EncryptedFile`) backed by KeyStore keys.
- 🔑 **Biometric Integration:** Open your vault folders securely using fingerprint verification or system PIN code.
- 📂 **Category Folders:** Instantly organizes your private downloads into Docs, Videos, Images, Epub, and Txt directories.
Notepad & Vault (DevNotes)
A secure offline notepad and scratchpad custom-tailored for saving sensitive texts, API keys, developer snippets, and login secrets.
- 📝 **Filterable Chips:** Switch categories instantly using tab selectors: All, Notes, Codes, and Keys.
- 🔍 **Fuzzy Local Search:** Scan and find your stored codes and developer notes using indexed search.
- 🎙️ **Voice Scratchpad:** Capture concepts hands-free using local, on-device audio transcription.
GeckoView WebExtensions Engine
Unlike standard WebViews that block add-ons, Omni features full integration with Mozilla's WebExtension controller to run desktop-grade plugins.
- 🔌 **Install .xpi Add-ons:** Install extensions directly from addons.mozilla.org (AMO) or local files.
- 🛡️ **Pre-bundled Shields:** Comes with uBlock Origin pre-configured to block ads, trackers, and miners instantly.
- 👾 **User Script Injectors:** Leverage Violentmonkey integration to load custom userscripts and CSS overlays.
Customize Site Style Engine
Tailor any website to your reading comfort with Omni's advanced real-time custom stylesheet injection utility.
- 🎨 **Theme Presets:** One-tap switching between Original, Dark, Sepia, Forest, and high-contrast OLED black themes.
- 📏 **Spacing Adjustments:** Fine-tune line-height, letter-spacing, and font sizes dynamically.
- 👓 **Accessibility Filters:** Enable Grayscale, Night Light (amber eye protection), or hide web images to save mobile data.
Advanced Video Player (PiP)
Omni overrides default web video elements with an embedded hardware ExoPlayer container, capturing background audio and multi-tasking layouts.
- 📺 **Picture-in-Picture:** Swipe out of the app to overlay floating windows on your Android home screen.
- 🎛️ **Gesture Controls:** Control brightness (left margin) and volume (right margin) with vertical swipe gestures.
- 📥 **Stream Sniffer:** Automatically intercepts HLS (m3u8), DASH (mpd), and MSE segments for native play or download.
Unified Quick Tools Panel
Access translators, scanners, code consoles, page style injectors, and auto-scrollers in a single bottom sheet.
- 🚀 **One-Tap Access:** Swipe up or tap the header menu to display the tool sheet.
- 🎛️ **Drag-to-Reorder:** Hold and drag tiles to personalize your layout grid based on your daily workflow.
- 🧩 **12+ Native Tools:** Pre-bundled with offline tools like a JavaScript dev console, PWA pinners, and code generator.
On-Device ML Translator
Translate entire web pages offline. Omni bundles Google ML Kit local translation packages to translate across 14 languages without hitting cloud servers.
Doc Scanner (ML Edge)
Zero-permission document scanner powered by Google Play Services ML. Automatically detects document edges, crop-aligns, and sharpens text completely offline.
Universal Text Copy
Bypasses annoying website copy blockages (such as user-select: none style overrides or context-menu locks) to force text selection.
Clean PDF Printer
Generates clean PDF prints of web articles, automatically stripping floating header banners, cookies pop-ups, and advertisements.
Instant Web App Pinning
Pin websites directly to your Android home launcher screen as dedicated, isolated PWA-style sandbox containers.
QR Scanner & Generator
Scan QR codes and barcodes using the built-in scanner, or convert URLs and text blocks into shareable QR codes instantly.
Jetpack Compose UI
Observe state, dispatch user interactions
BrowserViewModel
UDF State repository & command controller
GeckoSession
