## What it is
ZLS is a non-official Language Server Protocol implementation for Zig, written in Zig. It provides IDE features such as autocomplete, goto definition, diagnostics, formatting, and semantic highlighting in any LSP-compatible editor.

## Use cases
- add zig autocomplete to my editor
- goto definition for zig code
- zig language server for neovim
- format zig code on save
- find references and rename zig symbols
- zig inlay hints and semantic highlighting

## When to choose
- you write Zig and want IDE features in any LSP-capable editor
- you want diagnostics, formatting, and code navigation for Zig
- you need a language server that tracks Zig releases closely

## When to avoid
- you don't write Zig
- you need full comptime or semantic analysis support, which is still work-in-progress
- you require a stable API independent of Zig version churn - ZLS must stay in sync with your Zig version

## Facets
- artifact type: library
- maturity: active
- function: editor, developer-tools, documentation
- domain: developer-tools, programming-languages, text-editors
