Product updates
New features, improvements, and fixes. We ship updates regularly to make OnChange better for everyone.
Accessibility regression scans
OnChange now runs full axe-core WCAG scans on demand inside the same Chromium-based worker that captures visual diffs. Violations are diffed against a previous scan (or an attested baseline) and classified as new, persistent, or resolved. A new /audit/:id page renders a print-ready delta report for client hand-off, and detected Changes get a WCAG-aware impact badge alongside the existing AI summary.
- --On-demand WCAG 2.2 A/AA/AAA scans powered by bundled axe-core 4.10.2
- --Accessibility tree snapshot captures what screen readers see
- --Dynamic-content probes test modal focus traps and tab-order focus rings
- --Attest any scan as a VPAT baseline; future scans diff against it automatically
- --AI-written regression summaries in agency voice (not CI log text)
- --Per-monitor /monitors/:id/a11y history plus a global /a11y dashboard
- --WCAG impact classification pinned to every detected Change
AI-powered change summaries
Every detected change now includes an AI-generated summary explaining what changed and why it might matter. Summaries appear in your dashboard, email notifications, and Slack alerts. Powered by large language models with context-aware analysis of the page content.
- --AI summary generation for all detected changes
- --Natural language explanations in alert notifications
- --Context-aware analysis considers page type and content
- --Toggle on/off per monitor in notification settings
10-second check intervals
Business plan customers can now monitor pages as frequently as every 10 seconds. Ideal for tracking time-sensitive pricing changes, flash sales, or API endpoints where every second counts. Available for up to 50 monitors per account.
- --10s, 15s, and 30s check intervals for Business plans
- --Optimized infrastructure for high-frequency monitoring
- --Per-monitor interval configuration
- --Rate limiting to prevent target site overload
Discord integration and webhook improvements
Full Discord integration with rich embed messages. Webhook payloads now include structured diff data, making it easier to parse changes in custom automation workflows. Added retry logic with exponential backoff for failed deliveries.
- --Native Discord webhook integration
- --Rich embed formatting with before/after diffs
- --Structured JSON diff data in webhook payloads
- --Automatic retries with exponential backoff
- --Webhook delivery logs and debugging tools
Team collaboration and role-based access
Invite team members to your OnChange workspace. Assign roles (admin, editor, viewer) to control who can create monitors, modify settings, and access change history. Activity logs track all team actions for audit purposes.
- --Team workspaces with member invitations
- --Role-based access control (admin, editor, viewer)
- --Activity log for all team actions
- --Shared monitor ownership and transfer
Performance and reliability improvements
Fixed an issue where visual diff comparisons would occasionally produce false positives due to dynamic ad content. Improved screenshot rendering consistency and reduced P95 latency for change detection processing by 40%.
- --Fixed false positive visual diffs from dynamic ads
- --40% reduction in P95 change detection latency
- --Improved screenshot rendering consistency
- --Fixed email notification delivery delays
- --Resolved CSS selector targeting for shadow DOM elements
Visual diff detection launch
Introducing screenshot-based visual diff detection. OnChange now captures full-page screenshots on every check and highlights pixel-level differences between snapshots. Catch layout shifts, image changes, and visual regressions that text-based monitoring misses.
- --Full-page screenshot capture on every check
- --Pixel-level visual diff highlighting
- --Side-by-side before/after comparison view
- --Configurable sensitivity threshold
- --Visual diff history with timeline navigation
