Q.U.A.N.T.U.M
Studio
Quantum Unified Applications, Networks & Technology Utility Matrix
The code studio from the people who write Defendrix and AxiomCAD. Fast enough that you stop thinking about it. Your code stays on your machine. The editor is free forever — you pay only if you want the team-and-remote stuff.
An editor that respects the machine it runs on.
We write a lot of code — an antivirus, a CAD engine, this website. Quantum is the tool we built to do that work, shipped the way we wish someone had shipped it for us.
Fast is a feature
Native code, no browser runtime pretending to be an app. Cold start in well under a second, instant search across six-figure-line projects, and typing latency you can't perceive. The machine you paid for does the work.
Everything in the box
Syntax + smart completion for 40+ languages, integrated terminal, Git built in, project-wide refactors, a debugger that attaches without ceremony, and a plugin system for the rest. No extension safari before you can write a line.
Local-first, like everything we make
Your code never leaves your machine unless you explicitly turn on sync or share a workspace. No telemetry we didn't document. Same data policy as Defendrix and AxiomCAD — it's a company rule, not a product setting.
The editor is free. The team layer is the product.
The split is simple: everything one person needs to write serious software is in the free tier, permanently. Pro is for the moment your work involves other people or other machines.
