Short on time? Here's the quick answer
We've tested both tools. Here's who should pick what:
PMB
Local-first AI memory for coding agents. Recall context instantly
Best for you if:
- • You need something completely free
- • Open-source, local-first memory for AI coding agents that automatically records and recalls context without cloud dependencies
- • Injects relevant lessons, decisions, and project overview before the agent reasons, using sub-millisecond hybrid recall (BM25 + dense vectors + entity graph)
pumaDB
AI agent memory, simplified. No database admin needed
Best for you if:
- • Provides a memory API for AI agents to store and retrieve JSON data.
- • Offers both hosted MCP for agents and a REST API for server-side applications.

In-Depth Analysis
PMB
Local-first AI memory for coding agents. Recall context instantly
Strengths
- +Fully local and open-source (Apache-2.0) — no data leaves your machine, no API keys needed
- +Works across multiple AI coding agents (advanced models, Cursor, Zed) without losing context
- +Fast hybrid recall (minimal latency) with no LLM call on the read path, keeping latency minimal
Weaknesses
- -Requires initial setup and configuration for each agent (though simplified with pmb connect commands)
- -Focused on AI coding agents; may not be designed for general AI assistant memory (e.g., chat bots outside coding)
Key features
pumaDB
AI agent memory, simplified. No database admin needed
Strengths
- +Eliminates the need for manual database setup and management for agent memory.
- +Simplifies integration with AI agents via hosted MCP.
- +Provides built-in safety and reviewability for agent memory with versioning and limits.
- +Supports various types of structured memory relevant to agent operations.
- +Offers both agent-facing and server-side API access for flexibility.
Weaknesses
- -Memory storage is deliberately small and explicit, which might not suit very large data storage needs.
- -Rate limits could be restrictive for applications requiring very high-frequency writes or reads per key.
- -Focuses specifically on JSON records, limiting other data types.
