[ECC](https://ecc.tools) reports 228k GitHub stars, 35k forks, and 93 open issues, last pushed Jul 9, 2026. [eval-view](https://evalview.com) has 122 stars, 21 forks, and 6 open issues, last pushed Jul 3, 2026. Figures are from public GitHub metadata via [ECC's repository](https://github.com/affaan-m/ECC) and [eval-view's repository](https://github.com/hidai25/eval-view). | | [ECC](/tools/affaan-m-ecc.md) | [eval-view](/tools/hidai25-eval-view.md) | | --- | --- | --- | | Tagline | The agent harness performance optimization system for AI agents | Regression testing for AI agents.

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… - ECC is primarily JavaScript; eval-view is Python. - License: ECC is MIT, eval-view is Apache-2.0. - 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: claude, claude-code, llm, productivity. - 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 eval-view if… - eval-view is primarily Python; ECC is JavaScript. - License: eval-view is Apache-2.0, ECC is MIT. - Tags unique to eval-view: agent-benchmark, agent-evaluation, agentic-ai, autogen. - Also covers LLM Frameworks. - eval-view ships Docker support for self-hosted deployment. ## 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 eval-view - AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. - LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ## Common questions ### What is the difference between ECC and eval-view? ECC: The agent harness performance optimization system for AI agents. eval-view: Regression testing for AI agents. Snapshot behavior,diff tool calls,catch regressions in CI. Works with LangGraph, CrewAI, OpenAI, Anthropic.. See the comparison table for live GitHub stats and shared categories. ### When should I choose ECC over eval-view? Choose ECC over eval-view when ECC is primarily JavaScript; eval-view is Python; License: ECC is MIT, eval-view is Apache-2.0; 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: claude, claude-code, llm, productivity; 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 eval-view over ECC? Choose eval-view over ECC when eval-view is primarily Python; ECC is JavaScript; License: eval-view is Apache-2.0, ECC is MIT; Tags unique to eval-view: agent-benchmark, agent-evaluation, agentic-ai, autogen; Also covers LLM Frameworks; eval-view ships Docker support for self-hosted deployment. ### 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 eval-view? AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. Developer Tools: A gateway is overkill when you're pinned to a single provider and model. LLM Frameworks: Avoid a framework for a single prompt-and-retrieve call; the abstraction can cost more than it saves. ### Is ECC or eval-view more popular on GitHub? ECC has more GitHub stars (228,395 vs 122). Stars measure visibility, not whether either tool fits your constraints. ### Are ECC and eval-view open source? Yes - both are open-source projects on GitHub (ECC: MIT, eval-view: Apache-2.0). ### Where can I find alternatives to ECC or eval-view? GraphCanon lists graph-backed alternatives at [ECC alternatives](/tools/affaan-m-ecc/alternatives) and [eval-view alternatives](/tools/hidai25-eval-view/alternatives) ([ECC markdown twin](/tools/affaan-m-ecc/alternatives.md), [eval-view markdown twin](/tools/hidai25-eval-view/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-hidai25-eval-view.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, ECC or eval-view? ECC: Very active. eval-view: 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 eval-view? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [ECC trust report](/tools/affaan-m-ecc/trust); [eval-view trust report](/tools/hidai25-eval-view/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/_
