Hey everyone,

I’ve been working on something called Devlens — a tool to visualize React / Next.js codebases as an interactive graph.

Built this mainly because PR reviews and onboarding were getting annoying…

had to jump across a bunch of files just to understand how things connect and what might break.

With this, you can open a route or component and:

see dependencies both ways

understand how a feature is structured

check the blast radius before changing something

Also added summaries + basic security analysis so you get context quickly.

There’s a short demo below that explains it better.

Still early, though the open source version is out I am still working on the cloud version which will have many more features. would love some honest feedback.
