Letta
Stateful agent runtime with self-editing memory, from the MemGPT research.
Why it's indexed
Agents are persistent server-side objects that manage their own memory, rather than a context window you rebuild each call.
Editorial judgement, not a measurement — see our methodology. Listing is never paid for.
