Choose agentfield if…
- Tags unique to agentfield: agent-auth, agent-authentication, agent-scaling, agentic-ai.
- When you seek to manage and scale your AI agents with robust identity awareness and auditability features from inception.
When NOT to use agentfield
- If your project requires heavy customization in languages other than Go as Agentfield is primarily built using Go which may limit its adaptability in polyglot environments.
Choose letta if…
- Tags unique to letta: advanced memory, agents development framework, self-improving ai, stateful ai.
- When you require an AI agent with robust memory features that enable continuous learning and adaptation over time.
- More GitHub stars (24k vs 2.5k) - visibility, not fit.
When NOT to use letta
- If you are looking for a simple stateless AI solution without advanced memory capabilities, as letta is geared towards more complex stateful agent development.
- When your project's requirements involve strict limitations around data retention and privacy where even anonymized interaction logs might be considered sensitive.
