The short version

  • Only Zapier has a free tier, so it costs nothing to try first.
  • Each has a real cost: 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.; Zapier the free plan allows 100 tasks per month and only two-step Zaps, one trigger and one action

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

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.

Zapier

  • The free plan allows 100 tasks per month and only two-step Zaps, one trigger and one action
  • Multi-step Zaps, filters, paths, webhooks and the formatter all require a paid plan
  • Premium app connectors are withheld from the free plan
  • Free Zaps poll for new data every 15 minutes against 2 minutes on Professional and 1 minute on Team
  • Paying monthly rather than annually costs 50 percent more, so the 2,000-task Professional plan is $73.50 a month instead of $49
