One command center to diagnose and monitor your sites, APIs, DNS, and certificates. Find the root cause across DNS, TCP, TLS, and the app, not just that something is down.
Run any check on demand, then promote it to a monitor that watches around the clock.
Records, propagation, and resolver drift across regions.
Chain validation, expiry, and trust on the live cert.
Status, redirects, and phase timing down to TTFB.
Any check becomes a 24/7 monitor with routed alerts.
Four diagnostics, live. Run one, then let Synapse monitor it around the clock.
Issuer, chain, and days to expiry.
A, AAAA, CNAME, MX, TXT, NS.
Status, redirects, phase timing.
Resolver agreement worldwide.
