👋 Hey Product Hunters! We’re Joel, Justus & Florian. The team behind NanoAPI. NanoAPI started as an open-source tool to help developers untangle messy systems and visualize their internal architecture. It’s been amazing to see so many teams adopt it and tell us it gave them clarity they didn’t know they were missing. But we kept hearing the same thing: “We love what it does… but we don’t have time to set it up or maintain it.” So today, we’re launching NanoAPI Cloud: A fully hosted version of NanoAPI that gives teams the same instant clarity without any setup or infrastructure overhead. 🚀 Just connect your repo, and within minutes, you get: - A live map of your service dependencies - A shared view across engineering and architecture teams - Auto-syncing with your code, always up to date - Discover places where to refactor We built this for busy teams dealing with legacy complexity, fast growth, or painful onboarding. We’d love for you to try it and tell us what you think 🙌 Ask us anything, we're here all day! — Joel, Justus & Florian

@justusvmil @joel_milligan @florianbgt I’m curious—how does the platform ensure real-time synchronization with the codebase?

Congrats on the launch! How does this compare to something like CodeScene?

Hi @tim_sourcery, Our focus is to provide more context on the architectural details of software systems.

We already have an application library functionality, and in the coming weeks we will be launching linking: a process that auto-documents and generates views showing how services call each other (APIs, AMQP, etc).

Beyond even this we will be adding AI chat functionality soon which will enable talking with your entire architecture to better handle change management and planning for new features. This will come along with an MCP server to plug into tools like Cursor to provide better multi-repo context to the AI as it makes changes.

A valuable visualized tool for CTOs, technical leaders, architects, and developers to manage code effectively. Good job @NanoAPI Cloud!

Super excited to see the launch today! Pretty sure NanoAPI will come in handy for us to deal with some of our legacy codebases that have been waiting to get refactored for a long time now but nobody dares to touch them cause of all the unknowns.

Big kudos to the team and the open source community! Will make sure to drop our in-depth technical feedback later on the NanoAPI Discord. Until then, wish you the best with the launch ❤️

Nice work! This looks like it’ll be really helpful for troubleshooting.

Will there be frontend projects supported? Will private GitLab be supported?

Amazing team, and neighbours!
