ApiArk

Provides a unified interface for sending REST, GraphQL, gRPC, WebSocket, SSE, and MQTT requests, with features like TypeScript scripting, AI-powered request generation, and plugin support.

A local-first API development platform that supports REST, GraphQL, gRPC, WebSocket, SSE, and MQTT from a single interface, solving the problem of resource-heavy, cloud-dependent API clients.
