OnChange vs PageCrawl
PageCrawl is a capable all-purpose change-monitoring platform with protected-site crawling, automatic discovery, AI reports, broad integrations, and WACZ archiving. OnChange focuses on fast operational monitoring and specialized SEO, API, accessibility, and deploy-attribution workflows.
Both products are fully cloud-based and cover the core text, visual, AI-summary, and alerting jobs well. The deciding question is where your complexity lives: choose PageCrawl when collection and stakeholder reporting are the hard parts; choose OnChange when engineering-grade diagnosis, structured drift, and response speed matter more.

- You need dedicated JSON response monitoring alongside web pages
- WCAG scans and attested accessibility baselines belong in the same workflow
- Engineering needs Git commit correlation to investigate unexpected changes

Page-based allowances versus monitor-based pricing
Both products publish free plans. OnChange Free includes 5 monitors at 30-minute intervals; Pro is $12/month for 50 monitors at 60 seconds, and Business is $39/month for 300 monitors at 30 seconds. PageCrawl's July 2026 annual pricing publishes Free for 6 pages at 60 minutes, Standard at $160/year for up to 200 pages at 15 minutes, Enterprise at $300/year for up to 500 pages at 5 minutes, and Ultimate at $999/year for up to 1,000 pages at 2 minutes. PageCrawl also meters monthly checks and AI credits, so compare expected check volume—not page count alone.
A low-risk PageCrawl migration plan
Move a representative set first rather than recreating every monitor at once. Copy source URLs, selectors, and alert destinations into OnChange; then run both services through several expected changes to compare noise and rendering. Keep PageCrawl monitors that depend on login flows, automatic page discovery, WACZ, or scheduled stakeholder briefs until you have a deliberate replacement for those capabilities.
PageCrawl evaluation FAQ
Questions to resolve before moving from PageCrawl
- Is OnChange a good PageCrawl alternative?
- OnChange is the stronger fit when you need sub-minute monitoring, field-level SEO drift, JSON API diffs, WCAG scanning, or Git commit correlation. PageCrawl is stronger for protected-site workflows, automatic page discovery, scheduled stakeholder reports, WACZ archiving, and its broad integration catalog.
- Which is cheaper, OnChange or PageCrawl?
- Both have free plans. OnChange Pro is $12 per month for 50 monitors with 60-second checks. PageCrawl's July 2026 pricing publishes Standard at $160 annually for up to 200 pages with 15-minute checks; plan models and quotas differ, so compare required pages, monthly checks, users, and history together.
- Does PageCrawl monitor protected pages?
- Yes. PageCrawl publishes password-protected page monitoring, browser actions, proxy support, and optional CAPTCHA bypass. Teams that rely on complex gated workflows may prefer it over OnChange.
- Can OnChange replace PageCrawl's WACZ archive?
- No. OnChange provides a 90-day operational change history and shareable evidence views, but it does not currently export WACZ archives. Keep PageCrawl or another archival system if WACZ is a requirement.
