Argos vs SmartUI

Argos is a visual testing platform that stores screenshots uploaded by a team's test suite, compares them across builds, and supports review of visual changes. Argos does not connect to applications to capture screenshots. It can also diff Markdown, JSON, HTML, CSS, JavaScript, XML, YAML, and plain text. Integrations include Playwright, Cypress, Storybook, WebdriverIO, its CLI, or any framework, alongside GitHub Actions and deployment providers such as Vercel, Netlify, and Cloudflare. Teams can connect GitHub, GitLab, Slack, Discord, and Microsoft Teams. For agent workflows, Argos offers a remote MCP server, CLI workflows, and a REST API for inspecting diffs, reviewing builds, collaborating, and deploying previews. The Hobby Plan is free, billed forever, and includes up to 5,000 screenshots with 30-day retention. Pro costs $100 a month, billed monthly based on usage, and includes 35,000 screenshots and one-year retention. Argos says its SDKs and platform are open source and MIT-licensed, and that it is SOC 2 Type II and GDPR compliant.

SmartUI captures application UI screenshots and compares them with baselines to identify visual regressions across browsers, devices, apps, and PDFs. Its Visual AI filters rendering noise and explains meaningful differences, while Smart Ignore can mask dynamic regions and distinguish layout shifts from other changes. Root Cause Analysis compares screenshot differences with code changes and suggests fixes. The listed frameworks include Selenium, Playwright, Puppeteer, Cypress, Appium, Espresso, XCUITest, and Jest. SmartUI describes coverage across 3,000+ browser combinations and 10,000+ real devices, and supports Figma-to-live-UI comparison and PDF checks for text, layout, font, and graphic differences. Git branch-aware baselines work across branches and CI/CD pipelines; diffs and suggestions can be exported to Jira or Slack, with GitHub and GitLab integrations listed. The free plan includes 2,000 screenshots for lifetime use and one month of build history. SmartUI Visual Regression costs $199 a month, billed annually, and includes one year of build history; screenshot volume is selected with the plan.
