Feature
REST, GraphQL, gRPC, SOAP, WebSocket, SSE, Socket.IO and MCP
Write, save and organize requests across the protocols real local integration work uses, and run a folder of them at once.
How it works
One client for every protocol your services speak: REST with cURL import, GraphQL with a schema explorer and field completion, SOAP built from a fetched WSDL, gRPC from proto files or server reflection including streaming, WebSocket connections, and signed webhooks. Open server-sent event streams, Socket.IO namespaces with acknowledgements, and Model Context Protocol servers over stdio or Streamable HTTP, and call their tools. Requests have pre-request and post-response scripts and tests, a Cookies tab that decodes JWTs, and a Types panel that writes TypeScript, Zod, Python or Go types from their responses. A folder can be run as a whole, with an HTML report.
When to use it
- Test a gRPC service and the REST gateway in front of it from the same workspace.
- Call an MCP server's tools while you build it, over stdio or Streamable HTTP.
- Watch an SSE stream or a Socket.IO namespace and emit events with acknowledgements.
