<p>Note</p>
<ul>
<li>Scores are directional to aid selection; they will evolve as modules mature.</li>
<li>more ⭐️ indicates better integrated.</li>
<li>“Overall” is subjective and each project have its own benefits.</li>
<li>Extensibility and Orchestration are lacking for React FLow / Mini kanban doesn't mean it's bad. It means it is not opinionated about that part.</li>
