Echolot
The native Mac API client for HTTP, GraphQL, gRPC, WebSocket, Socket.IO, MQTT and MCP.
Echolot sends and inspects requests over HTTP/1.1, HTTP/2 and HTTP/3, GraphQL, gRPC, WebSocket, Server-Sent Events, Socket.IO, MQTT and MCP. It keeps your work in plain files you can put in Git, tests and automates APIs, designs and mocks them, and lets AI agents use your workspace with your approval.
These pages are being written. Start with the demo API: it works with nothing installed but Echolot.
