The Verdict
Photopea is built for designers and students, with a focus on photo-editing and psd-support. Windmill targets developers and devops teams and leads with workflow-editor and script-to-ui.
On pricing, Photopea is the clear winner for budget-conscious users — starting at $5/mo compared to $10/mo for Windmill. That $5/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 Photopea 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.
