Runner-up · #6 on this shelf
Knowledge graph memory in which each fact records when it became true and when it was replaced
Listed as the open-source engine behind Zep Cloud, so the same memory can run on your own machines.

The pick · #10 on this shelf
Stateful agents that edit their own long-term memory
Most rows above it are memory stores or graph builders outside the agent; in Letta the agent itself decides what to keep.

Runner-up · #16 on this shelf
Memory library for stateful agents, kept per user and per session
Listed because it reasons in the background to keep a picture of each person an agent deals with, not only a record of what was said.

Score colour shows how many signals stand behind it, never how good it is: amber, three or more; dimmer amber, two; grey, one. The Evidence column names them.
Stars, forks and last commit are as GitHub reported them when Armory last read each repository: for most, or later. A repository may have changed since.
Leaderboard ranks all 36 scored rows. Formula shows the calculation.
