About

Building the future of software creation.

XR was founded on a simple belief: software should be a collaboration between human intent and machine capability. We’re building the runtime that makes that real.

Today’s tools for building software still assume the human does all the typing, all the searching, all the coordination. That’s changing. XR is the runtime that lets agents plan, execute, and iterate alongside humans — safely, reproducibly, and at the speed of thought.

We’re a team of engineers and designers from Apple, Vercel, Anthropic, and Stripe. We care deeply about craft, performance, and the small details that make a tool feel inevitable.

Our principles

Local-first. Your data lives on your machine. The cloud is optional.
Composable. Small, typed primitives combine into powerful workflows.
Secure. Capabilities are explicit. Nothing runs without your say-so.
Open. The runtime is open. Ecosystems thrive on standards.
