Choose Living Brain if
Developers and AI-heavy teams who use several models and agents and want one portable memory layer behind them.
- Model-independent memory that follows you across AI tools
- Pay-as-you-go API with a $5 minimum and no subscription
- Many access routes: API, SDKs, CLI and MCP
Look elsewhere if: Teams that just need a note-taking app or a proven enterprise knowledge platform (Notion, Obsidian, Context Engine).
Choose OpenLLM if
Individual developers who pay for several AI plans and want every coding agent to use them through one endpoint with automatic fallback.
- Free tier is generous at 50M non-cached tokens a month
- Existing config such as ~/.claude is left unmodified
- Keeps agents running through rate limits with fallback chains
Look elsewhere if: Teams that need a self-hosted, governed gateway or pay-per-token access to many models without accounts (LiteLLM, OpenRouter).
