[ECC](https://ecc.tools) reports 228k GitHub stars, 35k forks, and 93 open issues, last pushed Jul 9, 2026. [evolver](https://evomap.ai) has 8.9k stars, 819 forks, and 3 open issues, last pushed Jul 9, 2026. Figures are from public GitHub metadata via [ECC's repository](https://github.com/affaan-m/ECC) and [evolver's repository](https://github.com/EvoMap/evolver). | | [ECC](/tools/affaan-m-ecc.md) | [evolver](/tools/evomap-evolver.md) | | --- | --- | --- | | Tagline | The agent harness performance optimization system for AI agents | GEP-powered self-evolving engine for AI agents | | Stars | 228,395 | 8,884 | | Forks | 35,037 | 819 | | Open issues | 93 | 3 | | Language | JavaScript | JavaScript | | Adopt for | ECC is a performance optimization system for AI agents built to enhance skills, instincts, memory, security, and development processes. | - | | Persona | - | - | | Runtime | - | - | | License | MIT | GPL-3.0 | | Categories | AI Agents, Developer Tools | AI Agents, Evaluation & Observability | ## Trust and health _Sourced signals - not a safety guarantee.

Specific setup details are not provided within repository data. - **Pricing:** freemium - Being open source with an MIT license, ECC itself is free to use, but additional features or support might incur costs outside of the core project. - **Adopt for:** ECC is a performance optimization system for AI agents built to enhance skills, instincts, memory, security, and development processes. ## Choose when ### Choose ECC if… - License: ECC is MIT, evolver is GPL-3.0. - ECC requires JavaScript environment and is open-source, licensed under MIT. Specific setup details are not provided within repository data. - Pricing: Being open source with an MIT license, ECC itself is free to use, but additional features or support might incur costs outside of the core project.. - Tags unique to ECC: ai-agents, anthropic, claude, claude-code. - Also covers Developer Tools. - When you are specifically working with AI agents like Claude Code and Codex that require advanced performance tuning across multiple dimensions such as skills and memory management. ### Choose evolver if… - License: evolver is GPL-3.0, ECC is MIT. - Tags unique to evolver: a2a, agent-evolution, auditable-ai, autonomous-agent. - Also covers Evaluation & Observability. ## When NOT to use ECC - For projects focusing solely on traditional software development workflows without AI components, ECC's specialized tools are not necessary. - In scenarios where you're working with closed-source or proprietary AI systems that do not allow for the same levels of customization as open platforms like those optimized by ECC. ## When NOT to use evolver - AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. - Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. ## Common questions ### What is the difference between ECC and evolver? ECC: The agent harness performance optimization system for AI agents. evolver: GEP-powered self-evolving engine for AI agents. See the comparison table for live GitHub stats and shared categories. ### When should I choose ECC over evolver? Choose ECC over evolver when License: ECC is MIT, evolver is GPL-3.0; ECC requires JavaScript environment and is open-source, licensed under MIT. Specific setup details are not provided within repository data; Pricing: Being open source with an MIT license, ECC itself is free to use, but additional features or support might incur costs outside of the core project.; Tags unique to ECC: ai-agents, anthropic, claude, claude-code; Also covers Developer Tools; When you are specifically working with AI agents like Claude Code and Codex that require advanced performance tuning across multiple dimensions such as skills and memory management. ### When should I choose evolver over ECC? Choose evolver over ECC when License: evolver is GPL-3.0, ECC is MIT; Tags unique to evolver: a2a, agent-evolution, auditable-ai, autonomous-agent; Also covers Evaluation & Observability. ### When should I avoid ECC? For projects focusing solely on traditional software development workflows without AI components, ECC's specialized tools are not necessary. In scenarios where you're working with closed-source or proprietary AI systems that do not allow for the same levels of customization as open platforms like those optimized by ECC. ### When should I avoid evolver? AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. Evaluation & Observability: Defer heavyweight eval infra only until you have real traffic - never skip it once users depend on answers. ### Is ECC or evolver more popular on GitHub? ECC has more GitHub stars (228,395 vs 8,884). Stars measure visibility, not whether either tool fits your constraints. ### Are ECC and evolver open source? Yes - both are open-source projects on GitHub (ECC: MIT, evolver: GPL-3.0). ### Where can I find alternatives to ECC or evolver? GraphCanon lists graph-backed alternatives at [ECC alternatives](/tools/affaan-m-ecc/alternatives) and [evolver alternatives](/tools/evomap-evolver/alternatives) ([ECC markdown twin](/tools/affaan-m-ecc/alternatives.md), [evolver markdown twin](/tools/evomap-evolver/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/affaan-m-ecc-vs-evomap-evolver.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, ECC or evolver? ECC: Very active. evolver: 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 ECC and evolver? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [ECC trust report](/tools/affaan-m-ecc/trust); [evolver trust report](/tools/evomap-evolver/trust). --- **Machine-readable endpoints** - JSON: [`/api/graphcanon/graph?tool=affaan-m-ecc`](/api/graphcanon/graph?tool=affaan-m-ecc) - 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/_
