Product comparison
OnChange vs Versionista
Versionista is an established enterprise web archival and change tracking tool built for compliance and regulatory teams. OnChange combines self-serve monitoring with coverage-qualified site scoping and accessibility evidence.
Versionista is built for regulated-enterprise buying patterns, indefinite archival, and account-managed programs. OnChange is built for teams that want to start quickly, define a complete public-site audit scope, compare retained site snapshots, and integrate operational alerts through Slack, webhooks, and a REST API. Teams with legal-grade retention requirements may still use an archival system alongside OnChange.

| Feature | OnChange | Versionista |
|---|---|---|
Self-serve signup and pricing Versionista is sales-led; pricing is custom and gated behind a demo. | ||
Free plan available | ||
Annual contract required Versionista typically requires annual commitments; OnChange is month-to-month. | ||

Text / content diff detection | ||
Long-term immutable change history OnChange provides retention-governed operational evidence and complete-site snapshots; Versionista is the stronger fit when indefinite archival is required. | ||
Coverage-qualified website scoping report OnChange freezes a complete public-site inventory with HTML, CSS, desktop and mobile captures, template groups, redirects, and automated WCAG evidence. Versionista provides broad archival and change tracking but not this same accessibility-audit scoping flow. | ||
CSS selector + XPath targeting | ||
API / JSON endpoint monitoring Versionista is a page-archival product; API monitoring is not a first-class feature. | ||

Choose the product that fits the work
Pick OnChange if
- You need a complete public-site inventory and preserved evidence set before estimating an accessibility audit
- You want enterprise-grade change tracking without annual contracts or procurement cycles
- Your team needs both page change detection and API/JSON monitoring in one tool
- You want sub-minute checks priced into a self-serve plan, not gated behind a sales call
- You need WCAG accessibility scans alongside content tracking for regulated industries
- You want a clean REST API for compliance automations and CI integration
- You'd rather pay monthly and scale as you grow than commit to a multi-year deal
Pick Versionista if
- You're a regulated enterprise with a procurement team that requires a master agreement
- You need legal-grade indefinite archival of every page version (not just 90 days)
- You already have a Versionista contract and dedicated CSM you're happy with
- You strictly require a vendor with white-glove onboarding and account management
Pricing
Versionista is sales-led with custom pricing typically starting in the thousands per year for enterprise tiers. OnChange is self-serve and transparent: Free for 5 monitors, $12/month for 50 monitors at 60s on Pro, $39/month for 300 monitors at 30s on Business, with Enterprise pricing available for 10s checks, dedicated support, and SLAs. Google and GitHub OAuth login is available on every plan.
Migration plan
If you're moving day-to-day monitoring out of Versionista, export the monitored URL list and recreate the watches in OnChange. Generate a fresh scoping report to establish the complete current public inventory rather than assuming the old watch list is exhaustive. For indefinite or legal-grade archival, keep Versionista or another records system in parallel with OnChange's retention-governed operational evidence.
