The ErrorDetector column is the product as shipped today: every number comes from the same constants the app enforces. A UptimeRobot cell appears only with a source and the date we checked it; we do not restate UptimeRobot's plans from memory. Their plans change — the link in each unverified cell goes to their current page.
For HTTP, keyword, ping, port and heartbeat monitors, yes: the concepts match and bulk import takes a CSV of URLs. What differs is what an incident tells you: ErrorDetector names the failure (DNS, TLS, refused, 5xx, keyword missing) and keeps reachability failures and failed checks apart in the uptime figure.
Because we have not verified them against their pricing page on a date we can print here. Every cell on this page carries a source and a date or says so; the link above goes to their current pricing.
