An integrated, in-browser API client for Laravel with a touch of magic.
Nimbus automatically analyzes your routes and validation rules to build interactive request schemas and a native interface for testing and exploring your APIs.

Traditional API testing tools require manual setup for every endpoint. Nimbus removes that friction by automatically discovering your Laravel routes, generating schemas from validation rules, and handling authentication, cookies, and test data. All without leaving your development environment.

Nimbus is NOT an API documentation generator. It doesn't produce client-facing API documentation. Instead, it's a developer-focused API playground designed to improve your development experience while building and testing APIs.

• Automatic route and schema discovery from Laravel routes and validation rules.
• Built-in, polished interface for testing API endpoints in your browser.
• Response viewer with JSON formatting and syntax highlighting.
• Cookie inspection with automatic Laravel cookie decryption.
• Special authentication modes:
  • Make requests as the currently logged-in user.
  • Impersonate other users by ID.
  • Bearer token and Basic Auth support.
• Inline value generators for realistic test data (UUIDs, emails, names, dates, etc.).
• Global headers automatically applied to every request.
• One-click payload population with realistic test data.
• Export requests as cURL commands.

• PHP 8.2 or higher.
• Laravel 10.x, 11.x, or 12.x.

Install via Composer:

composer require sunchayn/nimbus

Publish the configuration and assets:

php artisan vendor:publish --tag=nimbus-assets --tag=nimbus-config

This publishes config/nimbus.php and the necessary frontend assets.

Start your Laravel application and navigate to:

http://your-app.test/nimbus

That's it! Nimbus will automatically discover your API routes and their validation schemas.

Note: Nimbus requires a real web server (Herd, Sail, Docker, Nginx, etc.). PHP's built-in server (php artisan serve) will not work properly due to single-threaded request handling limitations.

• Contributor Guide - Architecture overview and development guidelines.

• Development Only: Nimbus is designed for local development environments. Do not deploy it to production servers.
• User Impersonation: The impersonation feature allows making requests as any user. Ensure Nimbus is only accessible in trusted development environments.

Nimbus is currently an alpha release to validate the concept. You may encounter unexpected behaviors or bugs. All feedback is welcome:
