The short version

  • Only Letta has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cyclr entry pricing of 1,595 US dollars a month for one connector and 100,000 API calls means small vendors will find building two or three integrations in-house genuinely cheaper, and Cyclr only pays off past a certain integration count.; Letta free tier limited to 3 stateful agents

Where each one falls short

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

Cyclr

  • Entry pricing of 1,595 US dollars a month for one connector and 100,000 API calls means small vendors will find building two or three integrations in-house genuinely cheaper, and Cyclr only pays off past a certain integration count.
  • Connectors and API calls are metered separately, so a successful integration marketplace pushes you up tiers as your customers adopt it, meaning the cost rises with usage rather than with the revenue that usage generates.
  • Custom connectors to APIs outside the library are your work to build and maintain, so the promise of not building integrations only holds for applications Cyclr already covers.
  • Debugging is harder when the integration runs in a third-party runtime, because your support team sees a failed workflow rather than an HTTP response and has to escalate to Cyclr for anything non-obvious.
  • Deep embedding creates real switching cost: your customers' live integrations run on Cyclr, so migrating later means recreating every customer workflow, which in practice means you rarely leave.

Letta

  • Free tier limited to 3 stateful agents
  • Pro tier capped at 20 stateful agents
  • API Plan usage charges apply beyond base tier
