The short version

  • Only Hevo Data has a free tier, so it costs nothing to try first.
  • Each has a real cost: Hevo Data billed on events ingested rather than on connectors or seats, so the bill tracks how chatty the sources are; Letta the Developer API plan charges $0.10 per active agent per month plus $0.00015 per second of tool execution on top of a $20 per month base and pay-as-you-go LLM usage, as of August 2026.
