Introduction

reqable is a browser extension for frontend developers that combines request monitoring with API mocking to make development, testing, and integration work faster. It focuses on the following problems.

🚀 Frontend development is blocked while backend APIs are unfinished

• Create mock data immediately without waiting for the backend API.
• Use dynamic response functions to simulate different business scenarios and data states.

🔍 API integration issues are difficult to diagnose

• Capture all XHR and Fetch requests from the current page in real time.
• Inspect methods, status codes, durations, request parameters, and response content in one place.
• Search, highlight, and inspect request details to locate failures quickly.

🎬 Real traffic is difficult to reproduce

• Export the current monitor list or a recorded interaction as mock rules.
• Organize rules into groups, import or export them, and reuse them across environments.
• Recover from temporary API failures with locally cached successful responses.

🤖 Mock data is expensive to create and maintain

• Import OpenAPI, Postman, HAR, cURL, and YApi data.
• Connect OpenAI-, Anthropic-, or Gemini-compatible services to generate and refine responses.
• Use normal mocks for fixed data and advanced function mocks for dynamic behavior.
