Developer tools that respect your time and your data.
Dev Nexus is a growing collection of fast, private utilities that run entirely in your browser — no installs, no accounts, and nothing ever leaves your machine.
Small tools, done exceptionally well.
Most everyday developer tasks — formatting some JSON, testing a regex, compressing a PDF, converting an image — shouldn't require an account, an upload, or an ad-riddled page that watches everything you paste.
Dev Nexustakes the opposite approach. Every tool runs on your own machine, in your own browser. Your data never touches a server, there's nothing to sign up for, and results are instant — even offline. It's the toolbox we wanted for ourselves: quick to reach for, honest about what it does, and built to get out of your way.
The platform is deliberately simple to grow — adding a new tool is a single change, so the collection keeps expanding without the bloat that usually comes with it.
The principles behind every tool.
No dark patterns, no data harvesting, no bloat — just tools that do one job well.

The toolbox is only the start. Here's what we're building around it.
