[ECC](https://ecc.tools) reports 228k GitHub stars, 35k forks, and 93 open issues, last pushed Jul 9, 2026. [stealth-browser-mcp](https://github.com/vibheksoni/stealth-browser-mcp) has 1.5k stars, 227 forks, and 1 open issues, last pushed May 24, 2026.

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; stealth-browser-mcp is Python. - 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, claude, claude-code, llm. - 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 stealth-browser-mcp if… - stealth-browser-mcp is primarily Python; ECC is JavaScript. - Tags unique to stealth-browser-mcp: ai-agent-tools, ai-tools, anti-bot-bypass, automation-tools. - Also covers Data & Retrieval. ## 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 stealth-browser-mcp - AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. - Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. - Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ## Common questions ### What is the difference between ECC and stealth-browser-mcp? ECC: The agent harness performance optimization system for AI agents. stealth-browser-mcp: The only browser automation that bypasses anti-bot systems. AI writes network hooks, clones UIs pixel-perfect via simple chat.. See the comparison table for live GitHub stats and shared categories. ### When should I choose ECC over stealth-browser-mcp? Choose ECC over stealth-browser-mcp when ECC is primarily JavaScript; stealth-browser-mcp is Python; 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, claude, claude-code, llm; 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 stealth-browser-mcp over 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 stealth-browser-mcp? AI Agents: Don't use an agent loop when a deterministic workflow would do; agents add latency, cost, and non-determinism. Data & Retrieval: Skip a heavy ingestion framework when your corpus is small and static; a script plus the embedding API is enough. Developer Tools: A gateway is overkill when you're pinned to a single provider and model. ### Is ECC or stealth-browser-mcp more popular on GitHub? ECC has more GitHub stars (228,395 vs 1,501). Stars measure visibility, not whether either tool fits your constraints. ### Are ECC and stealth-browser-mcp open source? Yes - both are open-source projects on GitHub (ECC: MIT, stealth-browser-mcp: MIT). ### Where can I find alternatives to ECC or stealth-browser-mcp? GraphCanon lists graph-backed alternatives at [ECC alternatives](/tools/affaan-m-ecc/alternatives) and [stealth-browser-mcp alternatives](/tools/vibheksoni-stealth-browser-mcp/alternatives) ([ECC markdown twin](/tools/affaan-m-ecc/alternatives.md), [stealth-browser-mcp markdown twin](/tools/vibheksoni-stealth-browser-mcp/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-vibheksoni-stealth-browser-mcp.md) mirrors this page for agents and LLM crawlers, with the same stats table and FAQ answers. ### Which is better maintained, ECC or stealth-browser-mcp? ECC: Very active. stealth-browser-mcp: Steady. 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 stealth-browser-mcp? GraphCanon publishes per-repo trust reports with dated maintenance, provenance, and scan summaries: [ECC trust report](/tools/affaan-m-ecc/trust); [stealth-browser-mcp trust report](/tools/vibheksoni-stealth-browser-mcp/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/_
