Make0 vs Letta
Updated October 30, 2026
TL;DR · Make0
Not an agent framework. One memory the agents and apps you already use can share through MCP.
TL;DR · Letta
A platform for building your own stateful agents that manage and improve their own memory.
The short answer
Letta, from the team behind MemGPT, is a platform for building stateful agents that manage their own memory, and it is Apache-2.0. Make0 is not an agent framework: it is one memory you own that the agents and apps you already use, such as ChatGPT, Claude, and Cursor, can share through MCP.

Questions
Is Letta the same as MemGPT?
Letta was founded by the researchers who created MemGPT at UC Berkeley, and it grew out of that work.
Can I use Make0 with agents I build on Letta?
Make0 exposes your Brain over MCP, so any agent that can call MCP tools can read from and write to it with the permissions you grant.
