Auto-generate an OpenAPI spec by listening to localhost▲178
Hey HN! We've developed OpenAPI AutoSpec, a tool for automatically generating OpenAPI specifications from localhost network traffic. It’s designed to simplify the creation of API documentation by just using your website or service, especially useful when you're pressed for time. Documenting endpoints one by one sucks. This project originated from us needing it at our past jobs when building 3rd-party integrations. It acts as a local server proxy that listens to your application’s HTTP traffic and automatically translates this into OpenAPI 3.0 specs, documenting endpoints, requests, and…

DeepDocs▲132
In my 15+ years as a developer, one of the most frustrating problems I've seen across teams is outdated documentation. I’ll be honest, I skip it myself. You ship a feature and move on. Then a month later, someone is onboarding or debugging and runs into stale docs that no longer reflect the code. I tried fixing this with tools like Swagger and Sphinx-autodoc, but they only work for narrow use cases like OpenAPI or annotations. They don’t help with the high-level stuff like onboarding tutorials, SDK guides, or user-facing examples. You still have to keep things like docstrings in sync, and…

Open-Sourced AI CLI Tool▲9
I’ve been working on Code2Docs, an open-source CLI tool that helps developers automatically generate inline documentation (docstrings + comments) for Python code using AI. It’s built to solve a common problem I’ve faced (and seen often in teams): We code by "vibe" — fast iterations, minimal docs, and then forget what the logic was months later. Code2Docs helps bridge that gap by documenting as you go — without breaking your flow. Right now it supports function-level documentation. Planned features include: - README.md generation for projects - API endpoint docs - Database schema…

Generate docs from your public repos▲27
Hello HN, I’m Andrew from docs.dev (https://docs.dev/), an AI powered docs assistant. With docs.dev you can generate your docs directly from your codebase, existing docs and other context sources. We don’t believe AI will replace technical writers—our goal is to make it easier for teams to get a solid first draft that they can review, edit, and improve. Think of it as a head start, not a finished product. More info on what we’ve built below but we wanted to release a quick, 1 minute, generate docs from your codebase tool. Try it out here:…
