What RequestBin is
RequestBin is a cloud service for capturing HTTP requests and testing DNS behavior. Each bin gets a unique URL that records incoming requests for inspection, including method, path, headers, body, source IP, and timestamp. New requests appear in real time without a page refresh. Users can build public HTTPS mock endpoints by defining rules for method, path, headers, and body, then setting the response status, headers, and body. Captured requests can be sent again to a destination URL with editable headers or body; this replay feature is for PRO users, blocks private and internal IP ranges, and limits replay bodies to 1 MB. The browser-based App Hub includes an HTTP requester, cURL and code converters, sample webhooks, and JSON, URL, and Base64 tools. The MCP server documentation names Claude Code, Cursor, and Windsurf as compatible agents. The free plan costs nothing and includes 3 bins, 500 requests per bin per day, 100 stored requests per bin, and 1 Mock API. PRO costs $12 a month and includes 20 bins, unlimited requests and history, 5 forwarding rules, and 20 Mock APIs.
