Show HN: OctAPI – Visualize API Routes Directly in VS Code https://ift.tt/Robtnmr

Show HN: OctAPI – Visualize API Routes Directly in VS Code Started noticing issues while working with friends that I thought only I was encountering: spending too long manually adding routes to postman, getting lost looking for a single route in the sea of files and thought Hey, I can fix that (I think?) So OctAPI is a VSCode extension that automatically detects and displays API routes from a local project (currently supports Express.js, NestJS, Next.js, Koa, Flask, and FastAPI), it filters and groups them, generates a Postman export JSON file, and adds to favs. It doesn't run your code and it all stays in your machine A friend literally screamed when they were live testing it for me lol It's open source ( https://ift.tt/lkKzhOe ) and here's its landing page ( https://ift.tt/y719IZq ) I'm hoping to add custom tags, more frameworks support and even AI features. https://ift.tt/zr3lkG1 April 13, 2025 at 01:48AM
