LSP Client for JetBrains IDEs

I provide a client implementation of the LSP standard for JetBrains IDEs. It allows to quickly integrate features provided by LSP and DAP servers into a plugin for JetBrains’ IDEs.

Implementing and maintaining a new language for JetBrains IDEs is complex and time-consuming. Many languages already provide an LSP server implementation to simplify the integration into editors and IDEs.

Please note that the LSP implementation is still experimental.
A DAP (Debug Adapter Protocol) client implementation will be available soon.

Integration with JetBrains IDEs

The client implementation is provided as a library. Extensive documentation is provided to help you integrate your LSP server into your plugin for JetBrains IDEs.

JetBrains IDEs 2024.2 and later are supported.
There’s a separate build of the library for each supported major version of a JetBrains IDE.

License and Pricing

The library is available for free for non-commercial plugins.

Non-Commercial Use

The LSP and DAP implementations are freely available for non-commercial plugins. A plugin is “non-commercial”, if it’s available for free and if it’s maintained and offered by an individual and not by a company or organization.

Commercial Use

Commercial plugins need to obtain a license.

Note: Commercial licensing is not yet available.
Please contact me if you’re interested to obtain a license.

Development Documentation

LSP Client Documentation provides extensive documentation how to integrate and customize the LSP client for your needs.

Source Code

The source code of the client implementation is not fully available.

The sources of the open API, which is to be used by plugins, is available on Maven Central alongside the library JAR files.
