Features

Everything your agents need

mem9 covers the memory lifecycle from first write to shared retrieval, without splitting the stack across local files, vector stores, and ad hoc sync scripts.

01

Instant memory backends

Provision a TiDB-backed memory store in seconds. No control plane, no manual schema setup.

02

Hybrid recall

Keyword retrieval works immediately. Add embeddings and mem9 upgrades into vector + keyword search.

03

Multi-agent by default

Claude Code, OpenCode, and OpenClaw can all write to the same memory graph with conflict handling.

04

Direct or server mode

Start direct against TiDB. Add mem9 server mode when you need spaces, tokens, and central control.

05

Portable memory

Memory lives in the cloud, not in local files. Your context follows the agent across machines and sessions.

06

Open source core

Apache-2.0 licensed Go server, TypeScript plugins, and bash hooks. Self-hosted when you need it.

Platforms
