The Verdict
Portainer is built for devops engineers and system admins, with a focus on container-management and stack-deployment. Windmill targets developers and devops teams and leads with workflow-editor and script-to-ui.
Pricing is close: Windmill starts at $10/mo versus $12/mo for Portainer — not a deciding factor on its own.
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 Portainer takes a more focused approach — which can mean a simpler, faster onboarding experience.
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.
