The Verdict
Grafana is built for devops teams and sre teams, with a focus on dashboards and data-sources. 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 $29/mo for Grafana. That $19/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, Grafana offers broader built-in capabilities (8 features vs 7), while Windmill takes a more focused approach — which can mean a simpler, faster onboarding experience.
Both tools are a solid fit for devops teams — in those cases, the decision often comes down to workflow style and how your team prefers to organize work.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
