A lab shipping native, local-first apps
Apps for the way you actually build.
Cortex Labs builds native, local-first apps for developers — an AI agent, a code editor, a database client, a Kubernetes browser, and persistent memory for Claude Code. Your machine, your data, no token tax. And we're just getting started.

We ship a new app whenever a tool we need doesn't exist yet — native, local-first, no compromises.
Built on one idea: your machine first.
Every app we ship runs locally by default. No data leaves your machine unless you ask it to, nothing burns API tokens behind your back, and everything stays fast because there's no round trip to a server you don't control.
Local-first
Your data lives on your machine, period.
Zero token tax
Uses your local CLIs and models by default.
Native & fast
Real apps, not Electron wrappers.
One family
Shared design and philosophy across every app.
