What RequestBin is
RequestBin is a cloud service for developers and cybersecurity professionals who inspect HTTP requests and test DNS behavior. Each bin has a unique URL that captures incoming requests, showing method, path, headers, body, source IP, and timestamp. New requests appear without refreshing the page. Users can create public HTTPS mock APIs with matching rules for method, path, headers, and body, then define response status, headers, and body. Captured requests can be replayed to another URL with editable headers or body; replay is a PRO feature, blocks private and internal IP ranges, and limits bodies to 1 MB. The browser App Hub includes an HTTP requester, cURL and code converters, sample webhooks, plus JSON, URL, and Base64 tools. MCP documentation lists Claude Code, Cursor, and Windsurf integrations. The free plan includes three bins, daily request limits, stored-request limits, and one Mock API. PRO costs $12 a month.
