Haskell Editor

A fast, modern editor for Haskell—precise syntax, smart tooling, and clarity-focused.

Precise Syntax Highlighting

Type signatures, monadic do-blocks, and infix operators are highlighted clearly, helping you stay focused in Haskell.

Semantic Understanding

Tree-sitter parses your code into a syntax tree, enabling features like code folding, selection expansion, and precise highlighting.

Instant Updates

Syntax highlighting updates in real-time as you type, with no lag or delay even in large files.

Error Recovery

Even with syntax errors, Tree-sitter maintains accurate highlighting for the rest of your code.
