Architecture assessment
- +Open-source (Apache 2.0) specialized for RAG and semantic search
- +Modular architecture with 100+ pre-built integrations
- +Excellent documentation and active community (25k+ stars)
- +Supports multiple LLM providers and local models
- +Production-ready with REST API and container deployment
- +Strong document retrieval and processing capabilities
- !Requires ML/NLP expertise for optimal pipeline configuration
- !Limited built-in monitoring and observability features
- !Setup complexity higher than managed services
- !Performance tuning requires deep understanding
- !Agent components arrived later in the 2.x line; agent tooling younger than dedicated agent frameworks
- !Document store choice affects performance and cost significantly
