OSPREY API TESTER

Smart NestJS API testing from controllers & DTOs in VS Code

What it does

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.

    Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
