The Verdict
Evidence is built for data analysts and data engineers, with a focus on sql-reporting and markdown-pages. Windmill targets developers and devops teams and leads with workflow-editor and script-to-ui.
On pricing, Windmill is the clear winner for budget-conscious users — starting at $10/mo compared to $49/mo for Evidence. That $39/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Windmill offers broader built-in capabilities (7 features vs 6), while Evidence takes a more focused approach — which can mean a simpler, faster onboarding experience.
