Languages & developer tools, built from scratch

Languages and developer tools, built by StretchGroup.

Owned, open, and yours to ship. We build our own foundations - a general-purpose language, a design-system compiler, and a typed authoring language for the web - and we hand them to you with documentation and direct downloads.

Languages & tools

Three foundations we built, and you can use.

Each language is a real, from-scratch StretchGroup project with its own purpose - a general-purpose language, a design-system compiler, and a typed web authoring language. Read the docs, then download.

Previewv0.4.0

General-purpose language

Vela

One language for data, systems, and everything between.

A from-scratch, versatile language that fuses Python's readability, Rust's safety and performance, and R's data and statistics power.

Python-grade readabilityRust-grade safety + speedR-grade data & statisticsNative, WASM & embeddableTiered ARC memory modelFirst-class dataframes

fn summarise(xs: [f64]) -> Stats {  let mean = xs.sum() / xs.len()  let sd   = xs.std()  Stats { mean, sd, n: xs.len() }} let report = summarise(sales.revenue)print("mean ${report.mean}, sd ${report.sd}")

Design-system compiler

Facet

Your design system is a compiler.

A zero-runtime, framework-agnostic design-system compiler over a typed token graph - a leap past Tailwind, StyleX, Panda and Radix.

Zero-runtime atomic CSSTyped token graphModes: theme x brand x densityFramework-agnosticReact Native / Swift / KotlinSwitch-safe contracts

Web authoring language

Quire

Author the web in a language that can't break.

A typed, safe, compiled authoring language for the web - the successor to Liquid and Handlebars, where code and a visual builder are two views of one model.
