Argos features
- Pixel-perfect diffs. Deterministic capture and diff of screenshots to highlight real visual changes.
- File diffs. Diffs for Markdown, JSON, YAML, HTML, CSS and JavaScript alongside screenshots.
- ARIA snapshots. Captures accessibility tree and diffs it like code to catch hidden regressions.
- Flaky test detection. Tracks unstable tests across builds and auto-silences noise.
- Live preview deployments. Generates immutable preview URLs for Storybook or static builds per PR.
- Team review workflow. Side-by-side review, pin comments to pixels, and enforce approvals via PR status.
- Agent-ready CLI & API. CLI and REST API let AI agents run visual checks and submit only needed changes.
- Budget controls. Per-screenshot pricing, spend limits and notifications keep costs predictable.
Velocity features
- AI prompt testing. Run AI-simulated user tests on interactive Figma prototypes before involving real users.
- Heat-map & click reports. Generate visual heat-maps and click data to see where users focus and miss-click.
- UX metric reports. Get success rate, time-on-task, drop-off and miss-click metrics for each simulation.
- WCAG accessibility review. Automated checks for accessibility compliance against WCAG standards.
- Human feedback integration. After AI simulations, request and collect human feedback within the plugin.
- Conversational insights. Chat with the AI to learn why simulations behaved a certain way.
