01
Reserve a name
Choose a project slug once. Bitrok combines it with your username to create a URL nobody else can claim.

How It Works
A fixed address for a moving backend.
The URL belongs to your project—not to a temporary session. Disconnect, restart, switch networks, and reconnect without touching frontend configuration.
02
Point it at localhost
Map the endpoint to any local port. Your service stays private until the CLI opens an authenticated tunnel.
localhost:300003
Configure the frontend once
Use the permanent endpoint in Vercel, Netlify, a mobile app, or a game client. Reconnect without changing it.
bitrok up excaliBuilt for demos that need to stay configured
Ship the frontend. Keep the backend close.
A serious public endpoint without paying to keep every experimental service running on cloud infrastructure 24/7.
APIs & webhooks
Test OAuth callbacks, payments, and third-party webhooks against local code.
Webhook testing
Expose OAuth callbacks, payment hooks, and event receivers against local code.
Vercel frontends
Keep one backend environment variable while development moves with you.
Internal tools
Share dashboards, Kafka UIs, and admin services without deploying each one.
Minimal by design
From zero to public in 3 commands.
No DNS edits per project. No random address to paste into Vercel. No cloud VM for every backend.
