[Athena-Public](https://winstonkoh87.com/athena/) reports 584 GitHub stars, 77 forks, and 0 open issues, last pushed Aug 23, 2026. [lean-ctx](https://leanctx.com) has 3.5k stars, 312 forks, and 5 open issues, last pushed Aug 4, 2026. Figures are from public GitHub metadata via [Athena-Public's repository](https://github.com/winstonkoh87/Athena-Public) and [lean-ctx's repository](https://github.com/yvgude/lean-ctx). | | [Athena-Public](/tools/winstonkoh87-athena-public.md) | [lean-ctx](/tools/yvgude-lean-ctx.md) | | --- | --- | --- | | Tagline | The Linux OS for AI Agents | Control what your AI can see by serving context with a local Rust binary. | | Stars | 584 | 3,486 | | Forks | 77 | 312 | | Open issues | 0 | 5 | | Language | Python | Rust | | Adopt for | Persistent memory & governed autonomy for AI Agents, built in Python. | LeanCTX serves as a context intelligence layer for AI agents, providing localized control over read access and memory management while optimizing token usage for numerous MCP tools, all powered by a local Rust binary. | | Persona | - | - | | Runtime | - | - | | License | MIT | Apache-2.0 | | Categories | AI Agents, Developer Tools | AI Agents, Developer Tools | ## Trust and health _Sourced signals - not a safety guarantee.

In such cases, using LeanCTX would incur overhead without providing significant benefits. ## Common questions ### What is the difference between Athena-Public and lean-ctx? Athena-Public: The Linux OS for AI Agents. lean-ctx: Control what your AI can see by serving context with a local Rust binary.. See the comparison table for live GitHub stats and shared categories. ### When should I choose Athena-Public over lean-ctx? Choose Athena-Public over lean-ctx when Athena-Public is primarily Python; lean-ctx is Rust; License: Athena-Public is MIT, lean-ctx is Apache-2.0; Tags unique to Athena-Public: chatgpt, framework, google-antigravity, knowledge-management; When you need persistent memory and structured reasoning capabilities that enhance any LLM used as an AI agent or assistant. ### When should I choose lean-ctx over Athena-Public?
