Tana alternatives
2 open-source projects that already do this job. Free to use - not free to run, which is what the numbers on the right are for.

What you give up either way
- Native in-call agent automation that acts during the video call
- Deep, supported integrations (MCP/API-first ecosystem) and turnkey connectors
- Enterprise security, compliance, and dedicated support (SOC2/HIPAA claims)
- Multi-agent orchestration, skills, and the full knowledge-graph UX
An open-source project doing the core job proves a replacement is possible. It does not prove it matches Tana, and it does not prove anyone has run it for a month. How we decide.
