Mokku

🚀 Take Control of Your API Workflows with Mokku
Stop waiting for backend deployments or struggling with unstable staging environments. Mokku is the ultimate developer tool that integrates directly into your Chrome DevTools to let you mock, modify, and manage API responses seamlessly.

Whether you're building a frontend against a non-existent API or testing edge-case error states, Mokku gives you the power of a full mock server right inside your browser.

🛠️ Key Features
1. Powerful API Mocking

Complete Control: Specify JSON bodies, HTTP status codes, time delays (latency), and custom headers.

GraphQL Native: Full support for mocking GraphQL queries and mutations.

Dynamic Responses: Go beyond static files. Write JavaScript functions to return complex, conditional data based on the request.

Dynamic URL Matching: Use patterns like /goals/:goalId (powered by path-to-regexp v8.2.0). URL parameters are passed directly to your response functions.

Pro Editor: Built-in Monaco Editor (the engine behind VSCode) for a premium coding experience.

2. Flexible Header Modification

Modify request headers globally or on a per-URL basis. Perfect for testing auth tokens or custom headers without touching your source code.

3. Effortless Organization & Portability

Projects: Group mocks and headers by project to keep your workspace clutter-free.

Import/Export: Share mocks with your team or backup your setup by exporting project-based configurations.

⚙️ How it Works
Mokku adds a dedicated tab to your Chrome DevTools. You can:

Click-to-Mock: Pick any existing network call from your logs and turn it into a mock with one click.

Start from Scratch: Create custom mocks manually for APIs that don’t exist yet.

Safe Injection: Mokku is non-intrusive. It only injects scripts into localhost by default. For all other domains, it remains inactive until you manually enable it from the panel.

🔒 Privacy First
Zero Data Collection: Mokku does not collect or request any personal information.

Secure Storage: Your mocks are stored safely within your Chrome profile storage.
