About Echolot
Echolot is a native Mac API client for HTTP, GraphQL, gRPC, WebSocket, Socket.IO, MQTT and MCP. It brings requests, live sessions, schema-aware completion, environments, authentication, response checks and test flows into one workspace for developers and API teams.
Workspaces are plain files that can be kept in Git, while secrets stay in the Keychain. Echolot shows wire-level details, redirects and timing, streams large response bodies to disk, and includes a command-line runner for CI, reports and Postman collections. It requires macOS 15 or later and Apple silicon.
