The ErrorDetector column is the product as shipped today: every number comes from the same constants the app enforces. A HetrixTools cell appears only with a source and the date we checked it; we do not restate HetrixTools's plans from memory. Their plans change — the link in each unverified cell goes to their current page.
Yes, on paid plans: a blacklist monitor queries the DNS-based blocklists we are allowed to query commercially, names each list in the result, and records "unknown" rather than "clean" when a query is refused. It is checked twice a day by design, because listings change over hours, not minutes.
No, and it will not: that is infrastructure monitoring for sysadmins. ErrorDetector monitors what a client of yours would notice: the site, its certificate and domain, its API, its scheduled jobs, its mail reputation.
100% EU-hosted infrastructure. No transatlantic data transfers, no surprises for your B2B clients' compliance teams.
Privacy isn't an afterthought. ErrorDetector is built to meet European data protection expectations out of the box.
Native Telegram, email, Slack & webhook alerts — so you know the moment a client site goes down.
Set up your first EU-based monitor in under a minute. No credit card, no sales call.
