OnChange vs Visualping
Visualping is one of the oldest website change monitoring tools, with a strong consumer and Chrome-extension presence. OnChange targets developer and agency teams who need faster checks, API monitoring, and deploy-aware debugging.
Both products detect changes on web pages and alert you. The choice comes down to speed, breadth (API monitoring and WCAG), and whether your team writes code. If any of those matter, OnChange will be the stronger fit; if you just need clean screenshot-based monitoring for a handful of pages, Visualping is well-built for that.

Pick OnChange if…
- You need sub-minute check intervals to catch flash sales, price drops, or API regressions
- You want JSON / REST API monitoring alongside page change detection
- Your team ships code and wants to know which commit caused which regression
- You're an agency or in-house team with WCAG compliance obligations
- You want every feature on every plan, with tier limits only on monitor count and frequency
- You want a REST API you can script against from CI or custom dashboards
Pick Visualping if…
- You only need visual screenshot-based monitoring, no API tracking
- You prefer Visualping's specific UI, Chrome extension workflow, or existing integrations
- Your use case is primarily personal or non-technical (they have a polished consumer UX)
- You want daily or weekly checks and don't care about sub-minute intervals
Pricing
Visualping's entry-level paid plan starts around $14/month for a handful of monitors with hourly checks. OnChange Pro is $12/month for 50 monitors with 60-second checks and every feature, and the free plan includes 5 monitors with 30-minute intervals - the same feature set as paid plans, just fewer slots.
Migrating from Visualping
Export your Visualping monitor list (CSV or screenshot the dashboard), then recreate the monitors in OnChange - our visual selector builder gives you the same element-picking experience. Notification channels (email / Slack / Discord / webhooks) translate directly; CSS selectors carry over unchanged. Most teams finish migration in under an hour.
