Analyzer LSP is a rule engine that provides code analysis through pluggable providers using the Language Server Protocol.

The tool addresses the need for consistent, language-aware code analysis across multiple programming languages. It works by implementing a rule engine that executes configurable analysis rules against source code, with language-specific providers built on the Language Server Protocol. This approach allows the engine to leverage existing language servers for accurate syntax and semantic understanding rather than implementing language parsing from scratch. Rules are defined in YAML format and can be filtered using label selectors, with analysis results output in a structured format.

Teams should consider this tool when they need to perform custom code analysis across multiple languages within a single framework. It suits projects that require extensible analysis capabilities, particularly those working with Java, Go, Python, Node.js, or YAML codebases. The tool provides both containerized demo environments and source-based execution, making it accessible for quick evaluation or integration into existing workflows. The README does not compare this project to alternative analysis frameworks.

The project maintains automated test coverage across all language providers and the core analyzer engine, with dedicated testing instructions for individual providers. Documentation is comprehensive, covering user-facing configuration of providers and rules alongside developer-focused guides for architecture, setup, and provider development. The codebase builds on established foundations, drawing from the Go language server protocol implementation and Google's JSONRPC2 library while stripping away unnecessary serving and proxy components.
