Argos vs Screenster

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.

Screenster is a UI regression testing tool for automating tests of web interfaces. Its no-code recorder captures actions on web pages without requiring code, element IDs, checks, or assertions. Test runs can be compared with a baseline to identify new, deleted, or changed visual and page content. Smart selectors can find page elements after they move or change and adjust timeouts automatically. Users can also write JavaScript or Java tests against the Selenium API within Screenster. The locally installed server can run offline. Screenster says it stopped running its online servers after August 1, 2023, and made local use free without restrictions. The installation guide requires Windows and lists Windows 8, 8.1, 10, Server 2012, and Server 2016; local browser documentation lists Chrome, Firefox, and Internet Explorer. Plans include Free at free, Basic at $25 a month, Standard at $45 a month, and Premium at $75 a month, each billed per tester per month.
