Homepage lists free SEO tools without registration; pricing lists Basic free and a 14-day Premium trial: https://www.seobility.net/en/ and https://www.seobility.net/en/pricing/
Sitechecker

Market proof
Estimated customer or user scale based on public claims, with source claims stored separately for auditability.

The vendor reports substantial user reach, but this is a self-reported user count rather than independently verified paying-customer data.
Homepage states “700,000+ users”: https://www.seobility.net/en/
Sitechecker
The official site makes a numeric first-party claim of 1,000+ teams/businesses, but no independently verified customer total is provided in the permitted sources.
The homepage says ‘Join 1000+ teams monitoring websites with Sitechecker.’ https://sitechecker.pro/

Seobility
Very early agent readiness: an MCP connector is announced as coming soon and the existing API is narrow and Agency-only.
Pricing marks Seobility MCP coming soon; API page says Agency Ranking Monitoring API only and deprecated dedicated API: https://www.seobility.net/en/pricing/ and https://www.seobility.net/en/seo-api/
Sitechecker
Public REST API, API keys, documented endpoints, and webhook-triggered audits create a strong automation surface.
The official docs describe a Public REST API for projects, GSC/GA4 performance, rankings, and AI visibility; pricing lists audit-via-webhook automation. https://docs.sitechecker.pro/guides/getting-started/ https://sitechecker.pro/account/plans/
Ease of use and autonomous level
Automation
How easy it is for a team to reach useful outcomes, and how much work the product can perform autonomously after setup.
Seobility
Automated scheduled crawling, alerts, and recommendations reduce manual work, but autonomous multi-step SEO execution is not documented.
Website Audit supports scheduled recurring crawls and prioritized issue roadmaps, while the product overview does not claim autonomous execution: https://www.seobility.net/en/website-audit/ and https://www.seobility.net/en/
