OPEN CORE STUDIO

We build what your
industry can't buy yet.

No vendor lock-in. No license that expires. The code is yours to run, fork, and build on — or have us build with you.

THE MODEL

Use the tools. Or build with us.

The tools are yours

Everything we build ships under Apache 2.0. Fork it, run it in your own infrastructure, contribute upstream. No account. No usage limits. No license clause that bites you later.

We go all in with partners

We work with a small number of teams on the problems we can't stop thinking about. Engineers inside the domain, building on our tools, sharing in the outcome. Not advisors. Builders.

OPEN SOURCE

The platform.

Apache 2.0. No usage caps, no lock-in, no license clause that bites you at scale. Run it yourself or build with us on top of it.

Kota0

The hard part of building vibe-coded apps, solved

An AI workspace where teams describe what they need and ship it. Structured plan, live preview, running software — no full engineering cycle for every internal tool.

FOUNDATIONS

Flight

One codebase instead of two

Write server logic next to the frontend components that need it. Flight picks it up, mounts it, handles the rest. One codebase, not two.

Scribe

Data modeling that holds its shape as you grow

Define your domain once; Scribe handles validation, versioning, and relationships as the product changes around it. Built for Postgres.

PARTNERSHIPS

When we go further.

For a small number of teams, we go past the tools. Engineers inside the domain, building the full system on our stack, sharing in the outcome. No handoff. No brief at arm's length.

WORK WITH US

Build it once.
Own it forever.

Tell us what you're building. We don't take everything on, but when the fit is right we go all in.
