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 internally, and a free tier for 20 hosts.
14 days of Pro to start, then free for 20 hosts. No card, nothing to install.

| An ISP link dropsthe public address from several locations, by ping or a TCP port, confirmed by a ping from an internal device | Unknown | Yes |

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.
