About this app

WebToApp turns websites, HTML projects, media libraries, and even server-side applications into installable Android APKs — entirely on the device.

Drop in a URL, pick the bits you want, and you walk away with an APK you can install, share, or sideload. Behind the scenes the app stitches together a configurable WebView, optional native runtimes (Node.js, PHP, Python, Go), and an APK builder that signs and packages everything in-process via com.android.tools.build:apksig. No remote build server is ever contacted.

Supported app types (the AppType enum): Web · HTML · Frontend (React / Vue / static builds) · WordPress · Node.js · PHP · Python · Go · Image · Video · Gallery · Multi-Web.

Highlights

- One-tap on-device APK builds — packaged, signed, and installed without leaving the phone. - Two browser engines — system WebView plus an optional GeckoView (Firefox) backend. The GeckoView engine ships arm64-v8a only and its native runtime is downloaded on first use, not bundled. - GitHub-backed Module Market — install community JS/CSS modules without shipping an app update; the catalog lives in this repository. - Bundled Chrome extension support — runs unmodified MV3 extensions inside the WebView. Ships with the BewlyCat extension as a working example. - Local server runtimes — Node.js, PHP, Python, and Go execute on-device via a local HTTP server. WordPress runs against the on-device PHP runtime. - Customisable WebView — UA spoofing, 28-vector fingerprint disguise, ad blocking, DNS-over-HTTPS, JS/CSS injection, payment scheme handlers. - App Modifier — clone an installed APK and re-brand it (icon, name, package) by patching its binary AXML manifest and re-signing. - On-device APK signing — create, import, export, and inspect keystores (MD5 / SHA-1 / SHA-256 fingerprints) right on the phone; choose V1/V2/V3 signature schemes and a custom V1 signature filename. - AI Coding — a skill-driven agent that builds web apps, extension modules, and full app types (HTML, React, Vue, Node, PHP, Python, Go, WordPress, etc.) on your phone, with inline preview and built-in image generation. - Per-app usage analytics — Stats screen with health monitoring and Vico charts. - Trilingual UI — Chinese, English, Arabic out of the box.
