About this app

Arbiter is two powerful tools in one app: a mock API server for developers
and a WiFi file sharing & media streaming server for everyone.

📡 SHARE FILES OVER WIFI — NO CABLE, NO INTERNET, NO ACCOUNT

Turn your phone into a local file server. Pick any folder, tap start, and
every device on your WiFi network can browse and download your files from a web browser. No app needed on the other device — just scan the QR code or open the link.

- WiFi file transfer between phone, PC, TV, Mac, and tablets
- Works completely offline — files never leave your local network
- Browse folders with a clean web interface from any browser
- Download files directly, or copy a direct link to any file
- No file size limits, no compression, no cloud upload

🎬 STREAM VIDEOS TO ANY BROWSER

Watch videos stored on your phone from your laptop, smart TV browser, or any other device — instantly, with full seeking support.
- Stream video over WiFi with no conversion or upload
- Beautiful media library with video thumbnails and durations
- Full seek and scrub support — jump to any moment instantly
- Play music files directly in the browser
- Multiple devices can stream at the same time

MOCK API SERVER FOR DEVELOPERS

Test your apps against a real HTTP server running on your phone. Define endpoints, save JSON responses, and add dynamic logic with JavaScript.
- Create mock REST API endpoints with custom JSON responses
- Dynamic responses with JavaScript — read request fields, compute values,
return conditional data
- Test mobile apps, web apps, and IoT devices against realistic APIs
- Request logging — inspect every incoming request in real time
- Perfect for offline development, demos, and API prototyping

🔒 PRIVATE BY DESIGN

Everything runs on your device and stays on your local network. No cloud, no
account, no tracking, no internet required. Your files are only accessible to
devices on the same WiFi network, only while the server is running.
