## What it is
clice is a next-generation C++ language server built from scratch on LLVM/Clang, designed for high performance and deep code intelligence. It introduces compilation contexts, template pseudo-instantiation for dependent type resolution, and first-class C++20 named module support.

## Use cases
- get code completion inside C++ template bodies
- work with C++20 named modules in my editor
- switch compilation contexts for multi-config projects
- handle non-self-contained headers in a language server
- replace clangd with a faster C++ language server
- go-to-definition for dependent types in generic code

## When to choose
- you work with heavy template-based C++ code where clangd struggles with dependent types
- your project uses C++20 named modules
- you need compilation context switching for headers or multiple build configurations

## When to avoid
- you need a battle-tested, maximally stable language server today
- you rely on clangd plugins or integrations not yet ported to clice
- your toolchain or platform is not among the supported release targets

## Facets
- artifact type: application
- maturity: active
- function: editor, parser, developer-tools
- domain: developer-tools, programming-languages, parsers
- platform: windows, cpp, editor-plugin
- tags: language-server, lsp, clangd, llvm, code-intelligence, cpp20-modules, code-completion, linux, macos
