Visual change detection
Capture screenshots and compare them against a baseline so PRs surface only the visual changes that matter.
Argos
Argos is a developer tool for visual and snapshot testing, collaborative reviews, and deployment previews. It helps teams and AI agents review screenshots, structured files, and UI changes before merge.
What Argos does
Argos is a developer tool for visual and snapshot testing, review, and deployment previews. It is positioned around product quality for teams and AI agents that ship changes quickly, especially when those changes show up as screenshots, structured text, or rendered UI output.
The product covers change detection in CI, collaborative review of diffs, flaky test handling, and debugging context for failed tests. The site also shows workflows for Storybook, Playwright, deployment previews, and AI-generated code, with support for GitHub and GitLab integrations plus Slack and Microsoft Teams notifications on paid plans.
Core capabilities
Snapshot testing for any file
Review Markdown, JSON, HTML, CSS, XML, YAML, and plain text alongside screenshots, so non-visual output can be checked in the same workflow.
Fast diff review tools
Group related diffs, use synchronized zoom, highlighters, keyboard shortcuts, and side-by-side or overlay views to inspect changes quickly.
Collaborative reviews
Pin comments to a specific pixel or text line, mention teammates, and resolve threads in the review itself.
Flaky test management
Track flaky behavior, instability over time, and build-level stability metrics, then ignore flaky changes when needed.
Test debugging context
Attach traces, replay information, and failure screenshots to help explain why an end-to-end test failed.
Common ways teams use Argos
Review UI changes in pull requests
Use Argos to compare screenshots and rendered output on pull requests so design or layout regressions are caught before merge.
Test component variations in Storybook
Run Storybook stories in CI and capture screenshots for different states, themes, viewports, or locales without duplicating stories.
Collaborate on review decisions
Let reviewers comment on a specific pixel or line, then bring in designers, engineers, or AI agents to resolve the thread together.
Manage flaky visual tests
Track instability across builds, identify flaky snapshots, and ignore noisy changes when a test is not reliable.
Debug failing tests
Attach traces and failure screenshots to failed runs so engineers can inspect what happened and debug end-to-end issues faster.

FAQ
What kinds of changes can Argos review?
Argos is aimed at teams that want to review visual and snapshot changes in CI, including screenshots, Markdown, JSON, HTML, CSS, and other text-based artifacts. The site also describes workflows for Storybook, Playwright, deployment previews, and AI-generated code changes.
Does Argos have a free plan?
The pricing page says Argos is free to start with no credit card required, and it offers a Hobby plan and paid Pro and Enterprise options. The Hobby plan is listed at $0 forever, while Pro starts at $100 per month billed monthly based on usage.
Can AI agents use Argos?
Yes. The site explicitly describes Argos for AI agents and says agents can see diffs as structured data, fix what they broke, and show their work before a human reviews what remains.
Can teams review changes together?
Argos supports collaborative reviews where multiple people can comment on the exact pixel or line that changed, mention teammates, react, and resolve threads together.
What is Argos best suited for?
The site highlights visual and snapshot testing for Playwright and Storybook, and it also shows deployment previews for Storybook, Vite, Next.js exports, or plain HTML. That suggests Argos is focused on front-end and app output review rather than general-purpose test management.
