Interactive
geometry for the
agentic era.
Turn expertise into shipped tools through conversation. You drive the loop; the agent closes it.
Agent-native
The loop closes inside the app.
Prompt the agent — it runs experiments, composes the working sequence, and a new tool appears beside the built-in ones. No code. No deploy. No wait.
Lunar is an interpreter of its own language — the interface, the logic, every workflow is written in it. The agent speaks that language natively: it writes typed programs, checked before they run — not buttons pressed on the outside. And because the app is the language, the agent can reshape the app itself: what works becomes a tool in the UI, beside the built-in ones.
Watch agents do real work in Lunar.

This is where the loop closes — Lunar, in a browser tab, on your own geometry. Open it and drive it yourself.
Performance
Fastest, on the record.
Every operation, measured against the strongest library in each ecosystem — same corpus, every language, open harnesses.
The speed isn't in the algorithms — it's in the architecture around them, and how that architecture meets the hardware. What's correct on paper is rarely fast in practice. And we have years of practice.
Open any benchmark.
trueform — geometry engine
The STL for geometry. Fast and exact mesh booleans, spatial queries, arrangements, and remeshing. Easy to use, robust on real-world data.
Open source
We don't adopt the frontier. We shape it.
Running computation this heavy in a browser outruns the tools the industry is built on. So when the compiler, the threading runtime, or the bindings break under us, we fix them at the source — upstream, in public.
