Pocket-Mocker – Browser-native visual API mocking tool for frontend developers

Summary: Pocket-Mocker injects a visual dashboard into the browser to intercept Fetch and XHR requests, enabling API mocking without code. It generates smart data, simulates errors and latency, and includes a Vite plugin for team synchronization.

What it does

Pocket-Mocker intercepts network requests in the browser and allows users to mock responses visually, generate realistic JSON data, and simulate network conditions. It integrates with Vite for syncing mock rules across teams.

Who it's for

Frontend developers needing a quick, code-free way to prototype and test APIs with realistic data and error simulation.

Why it matters

It eliminates the complexity of hardcoding mocks or configuring proxies, providing a lightweight, zero-config solution for API mocking and collaboration.
