Language + Components
Compose UI primitives with predictable syntax that maps cleanly to compiled web components.
Features
Built for language-driven frontend engineering.
From grammar authoring to runtime compilation, Mate keeps the entire pipeline visible and controllable so your team can reason about UI behavior, not just templates.
Syntax Highlighting
Powered by Mate highlighter and grammar captures, aligned with tree-sitter parse output.
AST Inspection
Inspect parsed nodes and ranges while editing to understand exactly what the compiler sees.
Runtime Safety
Compile in WASM and render in sandboxed preview for fast, isolated iteration.
Monorepo Friendly
Packages for parser, grammar, playground, and addons can evolve independently.
Workflow-Oriented
Built around quick write-parse-compile cycles to boost frontend architecture experiments.
