The official specification repository for the Language Server Protocol (LSP), a JSON-RPC-based protocol standardizing communication between editors/IDEs and language servers that provide features like autocomplete, go-to-definition, and hover documentation. It also covers the Language Server Index Format (LSIF) for rich code navigation without local source code.
Use cases
- standardize how editors talk to language servers
- implement a language server for my programming language
- add autocomplete and go-to-definition to my IDE without per-tool rework
- reuse one language server across multiple editors
- understand the LSP 3.18 specification
- enable code navigation in a web UI without local source via LSIF
When to choose
- you are building a language server or editor language integration and need the canonical protocol spec
- you want to avoid reimplementing language features for every editor or IDE
When to avoid
- you need an actual language server implementation or client SDK rather than the protocol specification
- you need a ready-to-run tool rather than a standards document
