A proprietary engine

Vel — the language, framework, registry and the Lume GPU renderer — is closed-source. There is no public download, package or source tree.

Built for serious work

Vel powers production apps where token-efficiency, native performance and beautiful-by-default UI matter. Access is granted to partners and clients.

Try the syntax now

The live playground runs the real engine in your browser via WebGPU + WebAssembly — write Vel and see it render, no install required.

This is what Vel looks like

Short widget names, theme tokens, and reactive state — a whole UI in a handful of lines. The playground compiles this to native WebGPU live in your browser.
