# Language Support
Serena's semantic code analysis capabilities build on **language servers** using the widely implemented
language server protocol (LSP). The LSP provides a set of versatile code querying
and editing functionalities based on symbolic understanding of the code.
Serena's semantic code analysis and editing capabilities are powered by two
main technologies:
* **Language servers** implementing the language server Protocol (LSP).
* **The Serena JetBrains Plugin**, which leverages the powerful code analysis and editing
capabilities of your JetBrains IDE.
Both backends provide a set of versatile code querying and editing functionalities
based on symbolic understanding of the code.
Equipped with these capabilities, Serena discovers and edits code just like a seasoned developer
making use of an IDE's capabilities would.
Serena can efficiently find the right context and do the right thing even in very large and
complex projects! So not only is it free and open-source, it frequently achieves better results
than existing solutions that charge a premium.

Language servers provide support for a wide range of programming languages.

## Language Servers
Serena incorporates a powerful abstraction layer for the integration of language servers
that implement the language server protocol (LSP).
It even supports multiple language servers in parallel to support polyglot projects.
The language servers themselves are typically open-source projects (like Serena)
or at least freely available for use.
We currently provide direct, out-of-the-box support for the programming languages listed below.
Some languages require additional installations or setup steps, as noted.

* **Bash**

Support for further languages can easily be added by providing a shallow adapter for a new language server implementation,
see Serena's [memory on that](https://github.com/oraios/serena/blob/main/.serena/memories/adding_new_language_support_guide.md).
## The Serena JetBrains Plugin
As an alternative to language servers, the [Serena JetBrains Plugin](https://plugins.jetbrains.com/plugin/28946-serena/)
leverages the powerful code analysis capabilities of JetBrains IDEs.
The plugin naturally supports all programming languages and frameworks that are supported by JetBrains IDEs,
including IntelliJ IDEA, PyCharm, Android Studio, AppCode, WebStorm, PhpStorm, RubyMine, GoLand, AppCode, CLion, Rider, and others.
When using the plugin, Serena connects to an instance of your JetBrains IDE via the plugin. For users who already
work in a JetBrains IDE, this means Serena seamlessly integrates with the IDE instance you typically have open anyway,
requiring no additional setup or configuration beyond the plugin itself. This approach offers several key advantages:
* **External library indexing**: Dependencies and libraries are fully indexed and accessible to Serena
* **No additional setup**: No need to download or configure separate language servers
* **Enhanced performance**: Faster tool execution thanks to optimized IDE integration
* **Multi-language excellence**: First-class support for polyglot projects with multiple languages and frameworks
Even if you prefer to work in a different code editor, you can still benefit from the JetBrains plugin by running
a JetBrains IDE instance (most have free community editions) alongside your preferred editor with your project
opened and indexed. Serena will connect to the IDE for code analysis while you continue working in your editor
of choice.
