What is Mock Studio?
An introduction to Mock Studio, the AI-powered Chrome extension for API mocking. Learn how it can speed up your development workflow.
Welcome to Mock Studio, the next-generation API mocking tool designed for modern web developers. If you are building a frontend application, you know the pain of waiting for backend APIs, dealing with unstable staging environments, or struggling to reproduce specific edge cases.
Mock Studio solves these problems by living where you work: Inside Chrome DevTools.
What is Mock Studio?
Mock Studio is a browser extension that intercepts network requests at the browser level. It allows you to simulate any API response—success, error, or loading state—without changing a single line of your application code.
Unlike traditional mock servers that require you to run a separate process or change your base URLs, Mock Studio integrates seamlessly into your browsing experience.
key Features
1. AI-Powered Data Generation
Writing massive JSON objects by hand is tedious. With Mock Studio, you can use our built-in AI (powered by Local LLMs or OpenAI) to generate realistic data instantly.
Prompt: "List of 5 users with realistic names, avatars, and recent transaction history." Result: A fully populated JSON array in seconds.
2. Zero Context Switching
Mock Studio lives in your DevTools panel. You do not need to Alt-Tab to a separate application or terminal. You can inspect network requests, see what failed, and mock it immediately with a right-click.
3. Local & Private
We believe your development data is yours. Mock Studio stores all your mocks and settings locally in your browser using IndexedDB. No cloud sync is required (unless you want it), and no data is sent to our servers.
4. Organization That Scales
Organize your mocks into Projects and Folders. Toggle entire scenarios on or off with a single click. Keep your workspace clean, even with hundreds of endpoints.
Why Choose Mock Studio?
- Speed: Iterate faster by removing backend dependencies.
- Reliability: Test edge cases (401 Unauthorized, 500 Server Error) that are hard to trigger against a real backend.
- Simplicity: No complex setup, proxies, or certificate installation. It just works.
