oraios/serena
Serena is a powerful open-source coding agent toolkit designed to transform large language models (LLMs) into fully-featured coding agents that operate directly on your codebase. It provides semantic code retrieval and editing capabilities similar to those found in integrated development environments (IDEs), enabling precise extraction and manipulation of code entities at the symbol level while leveraging the relational structure of the code. Serena supports a wide range of programming languages through language servers using the Language Server Protocol (LSP), including Python, Java, TypeScript, and indirectly others like Ruby, Go, C#, Rust, Kotlin, Dart, and C/C++. This makes it highly versatile for various coding tasks such as analysis, planning, designing new components, refactoring, and even executing code and reading logs. The toolkit integrates with LLMs via multiple methods: the Model Context Protocol (MCP) server, which supports integration with tools like Claude Desktop, VSCode, Cursor, IntelliJ, and others; Agno, a model-agnostic agent framework that allows the use of virtually any LLM including those from Google, OpenAI, Anthropic, or free models; and by embedding Serena's tools into other agent frameworks. Serena's design decouples tool implementation from framework-specific code, facilitating easy adaptation. Serena aims to provide a free alternative to subscription-based and API-costly coding agents, enabling developers to use powerful coding agents without incurring high costs. It supports autonomous coding workflows from initial analysis to implementation, testing, and version control commits. The project also offers a variety of tools and configurations to optimize coding workflows and improve productivity. Serena is actively used by its creators and contributes to the developer community by offering a robust, cost-effective solution for coding assistance powered by LLMs.
