## What it is
clangd is a language server that provides C/C++ IDE features such as code completion, diagnostics, go-to-definition, and refactoring to any editor via the Language Server Protocol. It is built on the Clang compiler and is part of the LLVM project.

## Use cases
- get code completion for C++ in my editor
- show compile errors as I type in C++
- jump to definition and find references in a C++ codebase
- run clang-tidy checks inside my editor
- rename symbols across a C++ project
- add IDE features to vim or neovim for C++
- automatically insert missing includes and namespaces
- format and refactor C++ code from the editor

## When to choose
- you write C or C++ and want rich IDE features in any LSP-capable editor
- you want compiler-accurate diagnostics and clang-tidy integration while editing
- you need fast, indexed cross-references and navigation in large C++ codebases

## When to avoid
- you work primarily in languages other than C/C++
- your editor has no LSP client support
- you need a full standalone IDE rather than editor integration

## Facets
- artifact type: service
- maturity: stable
- function: editor, developer-tools, parser, linter, formatter
- domain: developer-tools, programming-languages, text-editors
- platform: windows, cross-platform, editor-plugin
- tags: language-server, lsp, c-plus-plus, clang, llvm, code-completion, ide-features, static-analysis, clang-tidy, linux, macos
