Real-world workflows
We test how each tool behaves in the workflows it's marketed for, not just its demo flow, so the verdict reflects sustained use.
Integrations
We check official integrations, API surface, and the ecosystem around each tool — gaps here often decide which one ships into a team's stack.
Ease of use
Time-to-first-result and learning curve matter more than feature count. We score both and call out which audience each tool is actually built for.
