Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.
What each says it does
agent-memory
Save 60-90% on LLM token costs with intelligent memory compression. agent-memory automatically compresses tool output into structured observations, shares context across agents via a memory bus, and injects only relevant memory into each prompt — keeping your token budget under control. Features: auto-compression hooks (PostToolUse), token-budgeted context injection (SessionStart), semantic search via FTS5, cross-session persistence, and a token economics dashboard showing compression ratios and savings.
Echo Memory
Shared memory for AI agents, as a graph in your own Postgres. Writes never call an LLM.

Commands built only from what the marketplaces declare; the full set for every client is on each card.

Tools each declares
Neither one's marketplaces publish a list of tools, so there is nothing to compare.
Settings each asks for
Only agent-memory asks for
AGENT_MEMORY_DATAPYTHONPATH
Only Echo Memory asks for
ECHO_MEMORY_AGENT_IDECHO_MEMORY_DATABASE_URL (secret)ECHO_MEMORY_USER_ID
Settings as each marketplace publishes them. Asking for fewer is not better in itself.
