RouterFlip: A Simpler Way to Test and Switch Claude Code Routers, Accounts, and Models

If you use Claude Code with multiple API routers or accounts, constantly changing API keys, base URLs, and models can get annoying.

I built RouterFlip, a CLI/TUI tool designed specifically for Claude Code to make switching between different router setups much easier.

What is RouterFlip?

RouterFlip lets you manage your Claude Code configuration from one place:

For example:

You don't need to manually enter every model ID.

RouterFlip can test a router and automatically discover the models available through it.

You can refresh the list whenever the router's available models change.

RouterFlip includes a built-in testing system:

routerflip test GoRouter

Or test everything:

routerflip test --all

This helps verify that your router, account, and model configuration are actually working before using Claude Code.

Want to try another router without changing your normal Claude Code setup?

routerflip use GoRouter --temporary

Or make it your permanent configuration:

routerflip use GoRouter --permanent

If you have multiple API accounts for the same router, you can keep them together instead of creating separate configurations.

Then select the account you want to use.

Why a CLI?

I wanted something lightweight that doesn't require another desktop application running in the background.

Everything happens directly in the terminal:

npm install -g routerflip

Then:

routerflip

RouterFlip currently works on Windows, macOS, and Linux.

The Goal

The workflow is basically:

Router
  ↓
Account
  ↓
Model (optional)
  ↓
Temporary / Permanent
  ↓
Claude Code

No repeatedly editing environment variables or configuration files just to switch between setups.

Try It

Install RouterFlip:

npm install -g routerflip

Run:

routerflip

I'd love to hear feedback from other Claude Code users, especially if you use multiple gateways, accounts, or models.
