Currently Working on https://devlens.io which is an Open source Intelligent Codebase Visualizer for javascript, Reactjs, nextjs and nodejs for easy onboarding and easy PR review. The open source version is live at https://github.com/devlensio/devlensOSS

You can star the repo if you like the project. I am still working on cloud version which will have lots of features.

Also the main MOAT of Devlens is not the visualizer but the blast radius feature. Which essentially tells you if I change this file/function where it will affect my Codebase which is specially useful for PR review.
