OSPREY API TESTER

Smart NestJS API testing from controllers & DTOs in VS Code

Most API clients treat your API as a "black box"—manual URLs, methods, and JSON. Osprey API Tester is code-aware: it reads your NestJS controllers, DTOs, and decorators to auto-generate requests. Features include zero-config discovery, auto payloads, CodeLens buttons, smart param extraction, and a fully native VS Code workflow, removing context switching.

Building NestJS APIs often meant switching between IDE and Postman. Osprey API Tester brings testing directly into VS Code, auto-generating requests from controllers and DTOs. We built it to save developers time and reduce context switching. Give it a try and let us know what you think!
