WebToAppBuild Android APKs on your phone

An on-device APK workshop that goes far beyond URL wrapping — fork+exec real server runtimes, ship a hardened network stack, and export Play-ready bundles. No PC required.

WebToApp

From URL to a signed APK in three steps

  1. Pick a type

    Choose from 12 app types — a plain Web wrapper, HTML or Frontend builds, or on-device Node.js, PHP, Python, Go, WordPress servers.

  2. Fill in the basics

    A name, a URL or a project, an icon — then save. Every type shares the same configuration cards for network, privacy, appearance, and runtimes.

  3. Build and share

    Build APK signs on-device with V1/V2/V3, then share it or export a Play-ready AAB. No PC, no build queue.

Twelve app types, one builder

Web and Multi-Web

URL wrappers, tabbed hubs, portals, and link feeds.

HTML and Offline Pack

Package local HTML or zip builds, or scrape a site into a self-contained offline APK.

Frontend

Ship React, Vue, or Vite builds as a localhost-served APK.

Server runtimes

fork+exec Node.js, PHP, Python, or Go binaries that serve on a local port.

WordPress

A full portable WordPress site with PHP and SQLite running on-device.

Media and Gallery

Image and video players, albums, and portfolios as standalone apps.

A toolbox behind the editor

Agent

A tool-calling assistant with 57 built-in tools that can build, edit, and operate the whole app.

Extension modules

Inject JS/CSS, userscripts, or MV3 Chrome extensions into any generated app.

Hosts ad-block

20 built-in filter lists and per-app subscriptions, compiled into the shipped APK.

Linux environment

A Termux-style environment with real toolchains for building and running projects.

Port manager

Conflict policies, real stop handlers, and DNS bridging for every local server runtime.

App modifier

Clone and rebrand installed APKs, batch-import definitions, export templates.

Under the hood

12app types
57agent tools

The builder does its own binary patching — AXML/ARSC rewriting, permission pruning, AES-256-GCM resource encryption, 16 KB page-aligned native libraries — and keeps a low targetSdk shell so fork+exec runtimes keep working. The developer docs cover the full export pipeline.
