API Hook - Request Mocker

Intercept fetch and XHR network calls to mock dynamic JSON responses, latency, and status codes.

API Hook is a developer productivity utility designed to simplify local frontend testing, debugging, and API mock interception. Toggle interception globally on or off, add mock rules, match URLs with wildcard patterns (glob), adjust latencies to simulate network delays, and customize JSON response bodies and HTTP status codes. Features: - Fetch & XHR Interception: Override standard native browser request APIs securely inside page contexts. - Wildcard URL Matching: Define robust interceptor patterns (e.g. **/api/test-mocker). - Custom Latency Simulation: Apply simulated delays (in milliseconds) to verify loading states. - Status Code Overrides: Mock error states (like 404, 500) or successful status codes (like 200, 201). - Obsidian Dark Aesthetic: Premium, responsive user interface featuring glassmorphic controls. - Search & Filtering: Instantly search through your mocked rules by URL, body contents, method, or enabled status. - Traffic Monitor: Visually track and log intercepted requests inside the popup. - Draft Auto-Save: Automatically persists uncommitted rule inputs so you never lose your progress. - 100% Local Processing: Runs entirely inside your browser's local sandbox to protect your privacy and data security.
