Argos
By Argos. Category: MCP servers for testing. Homepage
Argos's documentation describes it as a visual regression testing service that compares screenshots, ARIA snapshots and text files using deterministic pixel diffing, which the docs state is not AI-based comparison. Screenshots come from existing Playwright, Vitest, Storybook, Cypress, WebdriverIO or Puppeteer tests and are uploaded from CI. GitHub and GitLab are native integrations. It runs as a hosted service. Its documented AI-facing feature is an official remote MCP server, with agent skills and a CLI, that lets AI agents inspect builds and review visual changes. The repository is MIT licensed.
