jtaak
A local-first API request engine and command-line client. It sends and times HTTP, GraphQL, Server-Sent Events, gRPC (unary and streaming), SOAP, WebSocket and MCP (Model Context Protocol) requests, connects to MQTT, Kafka, Socket.IO, AMQP and NATS, runs pre-request and test scripts in a sandbox, imports Postman, OpenAPI and cURL, and stores its data in SQLite. No account, no cloud, no telemetry: it only talks to the APIs you send requests to.
