hostnag vs Uptime.com
Uptime.com is a mid-market monitor with an unusually wide check list: HTTP, ping, TCP, UDP, DNS, SSL, WHOIS and RDAP domain expiry, domain blacklist, mail protocols, heartbeats, transactions, RUM, page speed and a Cloud Status check that reads 1,200 vendors' status pages. The mail records beside the blocklists, a link check confirmed from inside, and a free tier for five hosts.
Free for five hosts. No card, nothing to install.

UNKNOWN means their documentation did not say either way on the day we read it. PARTLY is covered with a limit noted in the cell.
What Uptime.com has that we don't
- Cloud Status checks covering 1,200+ vendors and their components, beside hostnag's five status page products.
- Transaction checks in a headless browser, real user monitoring and page speed audits.
- Malware and virus checks against the Google and Yandex Safe Browsing lists, and SSH, FTP, SFTP, NTP and UDP checks.
Switching
- 01List your checks from the Uptime.com API; each is one row.
- 02Put them in a CSV with at least the columns type and target (name, interval, port, keyword, expected_status and record_type are optional; the import dialog links a template) and upload it in the import dialog.
- 03HTTP(S) checks become http, TCP checks tcp, DNS checks dns with their record_type, SSL checks tls_cert, WHOIS and RDAP checks domain_registration; heartbeat checks become heartbeats with a new hostnag ping URL to point the job at.
- 04Ping (ICMP) monitors carry over as Ping monitors, run from hostnag's own probes.
- 05Domain Blacklist checks become a mail monitor on the domain, and Cloud Status checks become vendor status monitors if the vendor's page is Statuspage, Instatus, Better Stack, incident.io or status.io; add those from the wizard rather than the CSV.
- 06Transaction, RUM, page speed, malware, UDP, SSH, FTP and NTP checks have no counterpart in hostnag.
- 07Check intervals snap up to the nearest hostnag preset (1, 5, 15, 60, 360 or 1440 minutes).
- 08Monitors are created up to your plan's limit; the rest stay listed in the preview so nothing is lost silently.
