Kiln is a free tool for building production-ready AI systems. It supports RAG pipelines, evaluations, agents, MCP tool-calling, synthetic data generation, and fine-tuning.
- Seamlessly connect agents and tools through MCP servers/interfaces
- Build, fine-tune, and run models locally or remotely
- Generate synthetic data, orchestrate evaluations, and manage datasets
- Collaborate across technical and non-technical stakeholders via Git-based workflows
- Use a free, open source Python library to embed Kiln into your own systems
- Maintain data privacy: Kiln runs locally; external APIs are called only via your own keys
