    Outstanding README with clear dual-product positioning, feature highlights, and strong social signals (14k+ stars, active partnerships).

    Reasoning available in the full report.
  • Getting Running

    68

    Clear high-level setup steps but demanding prerequisites and scattered build/run commands across multiple contexts create friction.

    Reasoning available in the full report.
  • Finding Your Way

    75

    Strong architecture artifacts and clear monorepo structure, but navigating the 10,700+ file tree and multi-framework variants is cognitively heavy without a newcomer guide.

    Reasoning available in the full report.
  • Path to Contribute

    80

    Explicit contribution workflow with CONTRIBUTING.md, issue templates, and build/test scripts, but no beginner-labeled issues or starter task guidance.
