[memU](https://memu.pro) reports 14k GitHub stars, 1.1k forks, and 116 open issues, last pushed Aug 21, 2026. [Athena-Public](https://winstonkoh87.com/athena/) has 584 stars, 77 forks, and 0 open issues, last pushed Aug 23, 2026. Figures are from public GitHub metadata via [memU's repository](https://github.com/NevaMind-AI/memU) and [Athena-Public's repository](https://github.com/winstonkoh87/Athena-Public). | | [memU](/tools/nevamind-ai-memu.md) | [Athena-Public](/tools/winstonkoh87-athena-public.md) | | --- | --- | --- | | Tagline | Personal memory for agents with fast retrieval and self-evolving skills | The Linux OS for AI Agents | | Stars | 14,347 | 584 | | Forks | 1,062 | 77 | | Open issues | 116 | 0 | | Language | Python | Python | | Adopt for | memU offers fast memory retrieval and self-evolving skills for AI agents at lower operational costs. | Persistent memory & governed autonomy for AI Agents, built in Python. | | Persona | - | - | | Runtime | - | - | | License | Other | MIT | | Categories | AI Agents | AI Agents, Developer Tools | ## Trust and health _Sourced signals - not a safety guarantee.

Athena-Public: The Linux OS for AI Agents. See the comparison table for live GitHub stats and shared categories. ### When should I choose memU over Athena-Public? Choose memU over Athena-Public when License: memU is Other, Athena-Public is MIT; Tags unique to memU: agent-memory, claude-skills, harness, loop-engineering; Use memU when your project requires fast access to stored agent actions and memories which can adapt over time without needing human intervention. ### When should I choose Athena-Public over memU? Choose Athena-Public over memU when License: Athena-Public is MIT, memU is Other; Tags unique to Athena-Public: ai-agents, chatgpt, framework, google-antigravity; Also covers Developer Tools; When you need persistent memory and structured reasoning capabilities that enhance any LLM used as an AI agent or assistant. ### When should I avoid memU? Avoid using memU if your application mandates proprietary memory systems that are tightly integrated with specific agent architectures not supported by memU. memU is unsuitable for projects where the customizability and control over skill evolution are limited or require extensive manual adjustments, as this tool emphasizes self-evolving features. ### When should I avoid Athena-Public? If your project requires a platform with extensive pre-built integrations beyond mere memory management for LLMs, Athena-Public may not offer sufficient out-of-the-box integration support. ### Is memU or Athena-Public more popular on GitHub? memU has more GitHub stars (14,347 vs 584). Stars measure visibility, not whether either tool fits your constraints. ### Are memU and Athena-Public open source? Yes - both are open-source projects on GitHub (memU: Other, Athena-Public: MIT). ### Where can I find alternatives to memU or Athena-Public? GraphCanon lists graph-backed alternatives at [memU alternatives](/tools/nevamind-ai-memu/alternatives) and [Athena-Public alternatives](/tools/winstonkoh87-athena-public/alternatives) ([memU markdown twin](/tools/nevamind-ai-memu/alternatives.md), [Athena-Public markdown twin](/tools/winstonkoh87-athena-public/alternatives.md)), ranked by typed relationship edges rather than popularity votes. ### Is there a machine-readable version of this comparison? Yes. The markdown twin at [this comparison](/compare/nevamind-ai-memu-vs-winstonkoh87-athena-public.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, memU or Athena-Public? memU: Very active. Athena-Public: Very active. Compare maintenance labels, days since push, and release cadence in the trust section below - stars alone do not measure maintenance. ### Where are the full trust reports for memU and Athena-Public? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [memU trust report](/tools/nevamind-ai-memu/trust); [Athena-Public trust report](/tools/winstonkoh87-athena-public/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=nevamind-ai-memu`](/api/graphcanon/graph?tool=nevamind-ai-memu) - LLM index: [/llms.txt](/llms.txt) - Full corpus: [/llms-full.txt](/llms-full.txt) _GraphCanon - The knowledge graph for AI development. https://www.graphcanon.com/_
