The fair-code workflow automation tool
Overview
What Letta does
Stateful AI agent platform where agents keep persistent memory and evolve through experience.
The honest half

- 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.

Softwr does not host reviews and shows no star rating for Letta, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it. Tell us if any of it is wrong.
