Where Percy wins. Percy renders your snapshots across multiple browsers in its own cloud, so you get cross-browser visual coverage without running those browsers yourself. It's the more mature tool, with a full review-and-approval workflow.
Where Argos wins. Argos is open source, surfaces visual diffs directly in your pull requests, and costs less per screenshot (free 5,000 screenshots/month for one user, Pro from $100/month billed monthly for 35,000, $0.004/shot overage). Percy's Desktop plan is $199/month billed annually for 10,000 with $0.036/shot overage. In exchange, you rely on the browsers you already run in CI rather than a cloud rendering service.
Common questions
Percy vs Argos: common questions
Is Argos a good Percy alternative?
Yes, for teams that want a PR-native visual tester with a lower per-screenshot price. Argos is open source, integrates tightly with GitHub, and surfaces diffs directly in pull requests. Percy is more mature and offers cloud cross-browser rendering, but costs more per screenshot ($0.036 per extra screenshot against Argos's $0.004). If a lower bill and a GitHub-native workflow matter most, Argos is a strong fit.
How does Argos pricing compare to Percy?
Both publish their prices. Argos has a free Hobby plan with 5,000 screenshots/month for one user, then Pro from $100/month billed monthly on usage with 35,000 screenshots and overage at $0.004 per standard screenshot ($0.0015 for Storybook). Percy has a free plan with 5,000 screenshots/month and unlimited users, then Desktop at $199/month billed annually ($249 billed monthly) for 10,000 screenshots, with extra screenshots at $0.036 each.
Does Argos do cross-browser rendering like Percy?
Not to the same degree. Percy renders uploaded snapshots across multiple browsers in its cloud. Argos focuses on diffing the screenshots your own test run produces, so cross-browser coverage depends on the browsers you run in CI rather than a rendering service.
