Use cases

• Search codebases locally without sending data to the cloud
• Query technical documentation using natural language
• Integrate RAG capabilities into MCP-compatible development tools

Pros

• Fully private, no data leaves the machine
• Zero setup, works out of the box
• Supports both MCP and CLI interfaces

Cons

• Limited to local resources, may not handle very large datasets efficiently
• Small community with 290 stars, fewer integrations and extensions
• Relies on local compute, can be slower than cloud alternatives for complex queries
