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
