Celestio Tools
Our diagnostic toolbox is going public.
Built by our engineers for our own diagnostics, now being prepared for everyone. Each tool publishes here when it can run real checks against any WordPress site. No simulations, no fake numbers.
The toolbox
Six tools on the bench.
What each tool will do when it ships. Every card stays honest: nothing here goes live until it measures the real thing.
Speed test
Time to first byte measured with real probes against your actual site: the number your visitors feel, not a lab score.
Performance · coming soonCache checker
See whether your host is actually serving cached pages, what the hit headers say, and where the misses come from.
Performance · coming soonData residency inspector
Trace where a site is really hosted (origin, DNS, email) and flag every non-EU hop. Useful ammunition for your DPO.
Compliance · coming soonWP health check
Detect the WordPress version, PHP version and exposed endpoints visible from the outside, before someone else does.
WordPress · coming soonMigration estimator
Answer a few questions about your site and get a realistic migration plan: duration, DNS strategy, and what could go wrong.
Planning · coming soonUptime pinger
Regular checks against one site from Sweden, with a plain log of the results you can share.
Monitoring · coming soonMeanwhile
The tools find problems. We already fix them.
Want the numbers before the tools publish? Ask us. An engineer will run the checks on your site by hand and send you what we find.
