CodeSee, once a beloved open-source tool for visualizing and understanding complex codebases, recently made the decision to go closed-source. For those who haven’t used it, CodeSee provided developers with an intuitive way to map out code flows, helping teams make sense of sprawling codebases. Their product saw solid growth by catering to teams struggling with legacy systems, but the recent acquisition and move to closed-source left a gap for open-source enthusiasts and developers looking for similar functionality.

Enter NanoAPI—we’re stepping in to fill the void and push the envelope further. NanoAPI aims to bring back what developers loved about CodeSee but with a twist: code splitting via the UI. By focusing on breaking down monolithic codebases into manageable, microservice-friendly components, NanoAPI will empower developers to modernize their stacks without losing sight of the big picture.

Initially, our focus will be on API codebases. APIs are the backbone of modern software, yet they often suffer from technical debt and tangled logic. NanoAPI will provide deep insights, automated refactoring suggestions, and actionable visualizations to help teams tackle these challenges head-on.

This is just the beginning, and we want the HN community to join us on this journey. Whether you’re a dev looking for a powerful tool, or someone passionate about improving developer experience, we need your help.

Star the project on GitHub and consider contributing to steer the ship! Together, we can build something that benefits the entire developer community.
