Ruby LSP is an opinionated implementation of the Language Server Protocol for Ruby, maintained by Shopify to provide rich editor features like completion, go-to-definition, diagnostics, formatting, and test integration. It ships as a gem usable with any LSP-compatible editor and as a VS Code extension with extra features.

Use cases

• add autocomplete and go-to-definition for Ruby in my editor
• set up a language server for Ruby in Neovim or Emacs
• format and lint Ruby code on save
• run and debug Ruby tests from the editor
• get inline hints and semantic highlighting for Ruby
• rename symbols and find references across a Ruby project
• get ERB and Rails support in VS Code

When to choose

• you write Ruby and want a modern, actively maintained LSP with batteries-included features
• you use VS Code, Neovim, Emacs, Sublime, or Zed and want consistent Ruby tooling
• you want test integration, indexing, and Rails-aware features out of the box

When to avoid

• you need a highly configurable, non-opinionated language server with pluggable backends
• your project depends on a legacy Ruby version unsupported by the tool
• you prefer Solargraph or another LSP you already have configured
