"Project memory" for coding agents can mean very different things. I compared Keep the Why, Claude Code Auto Memory, MemoryCustodian and AgentsRoom using three questions: Where does the memory live? Who can read it? What does it actually remember? The interesting result: most of these tools are not direct competitors. Session memory remembers what happened. Project state remembers where the project is. The rationale layer remembers why the project became what it is. Different layers, different tools, different trade-offs. https://blog.technopathy.club/keep-the-why-vs-claude-code-auto-memory-vs-memorycustodian-vs-agentsroom #AI #AIAgents #CodingAgents #ClaudeCode #DeveloperTools #OpenSource #ProjectMemory #RepoNative #KeepTheWhy
