When to stay with Mem0
Documented strengths from our Mem0 review — switching isn't always the right call:
- Genuine free tier with 10,000 monthly add requests and no credit card gate, enough to prototype a real agent
- Apache-2.0 open-source core means you can self-host and avoid vendor lock-in entirely
- API-first design with the same core methods in the self-hosted and managed versions, so migration is mostly a client swap
