Argos vs VisWiz.io

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.
