r2web: Access radare2 from anywhere, anytime.

r2web.mp4

Overview

r2web lets you run radare2 without local installs or platform hassles. Analyze files directly in your browser. It runs entirely client-side using radare2 WASI and Wasmer, with an xterm.js frontend for interactive command execution.

👉 Try it live

Features

Browser-based: No local installation required
Cross-platform: Works on any device with a modern browser (since older browsers don't support WASI/WASM)
Terminal Interface: Interact with r2 via a familiar terminal.
Keyboard Shortcuts: Navigate quickly using some known GUI shortcuts (like Ctrl+G for seek).
Search: Ability to search in large outputs of commands.
Custom r2 versions: Use any version of r2 you want.
Quick Buttons: Buttons for common commands like pd, px, iz.

Under the Hood

r2web uses:

React+TypeScript+Vite
xterm.js for the terminal interface
Wasmer for running WASM
r2wasm for the WASM build of radare2

Development

To run locally:

git clone https://github.com/AbhiTheModder/r2web.git
cd r2web
bun install
bun dev

Or skip the setup and try it live.

Tip

If you don't have bun installed, you can use npm or yarn or any other package manager which you have installed. Just replace bun with npm or yarn (or any other package manager) in the above commands.

Notes

This is a work in progress. Expect bugs and missing features.
The radare2 binary is downloaded on first load and cached for future use (an option to disable caching is also given).
No history support.
Currently there's no way to save modified files, (seems like an issue on r2wasm side), figuring out a way to fix it.
