Overview
Product summary
Review the store description, core capabilities, and common use cases.
Intercept, modify, and mock HTTP requests with ease. A powerful developer tool to streamline your API development and testing workflow.
API Pilot is the ultimate browser extension for front-end developers, QA engineers, and API producers. It allows you to take full control of your browser's network traffic without needing complex proxy setups or external desktop applications.
Key Features:
- Intercept & Modify: Seamlessly intercept outgoing API requests and modify headers, query parameters, or payloads on the fly.
- Dynamic Mocking: Create robust mock responses for your APIs. Temporarily override server responses to test edge cases, error states, or features still under development.
- API Tester & History: Replay past requests, tweak parameters, and test endpoints directly from the integrated, persistent sidebar.
