Vezlo

Vezlo is an open-source SDK for turning software codebases into searchable knowledge bases that AI assistants can understand. Its source-to-KB tooling analyzes code structure, dependencies, and relationships rather than treating files as plain text. It supports languages including JavaScript, TypeScript, Python, Go, and Rust, then creates embeddings and semantic relationships that can be queried through natural language. Developers can access the resulting knowledge base through a CLI, REST API, or MCP server. This can help SaaS teams build assistants that answer questions about application architecture, routing, authentication, APIs, or other implementation details. Vezlo is particularly useful for teams that want their AI assistant to understand an existing codebase instead of relying only on generic model knowledge.
