Stackbrace vs UptimeRobot
UptimeRobot is the standard uptime monitor: many monitors, fast checks, low price. Stackbrace checks less often and watches fewer sites, and spends the difference on what happens after the alert: which layer failed, who can fix it, and the record that outlives the person who set it up.
UptimeRobot’s side as read on uptimerobot.com/pricing, 26 October 2026; Stackbrace’s from its plan settings
| UptimeRobot | Stackbrace | |
|---|---|---|
| Checks from outside | Every 5 minutes free, down to 15 seconds on paid plans | Every 5 minutes on paid plans, daily on Free |
| How many sites | 50 free, up to 500 on Scale | 1 on Free, 5 on Business, 25 or more on Agency |
| Price | Free; Solo $9 to $10, Team $30 to $35, Scale $55 to $65 a month | free for 1 site and 2 people, checked daily; $19 a month for 5 sites and 3 people |
| What the down alert says | That the monitor failed, with the response | Which of the five layers failed, who holds its login, and the first steps you wrote for it |
| Certificate and domain expiry | Alerts at 30, 14 and 7 days, on paid plans | Domain at 30, 14, 7 and 1 days; certificate at 14, 7 and 1; on every plan, naming who pays |
| Who controls each layer | Not recorded | The registry: registrar, DNS, hosting, backups and application, with who holds each login, dated and re-asked |
| Security | Not checked | A daily scan: known holes in WordPress, plugins, themes and script libraries; email anyone could fake; nameserver and registrar changes; Google's blocklist |
| Status pages | Yes, white-label on Team and above | No. A health card per site for clients, on Agency |
| Alert channels | Email, SMS and voice, Slack and Teams on paid plans, webhook and PagerDuty from Team | Email on every plan; Slack and a signed webhook on Business |
| Incident record | Comments and post-mortems on paid plans | A page per outage: the diagnosis, who to call, the runbook, a log, and lessons saved into the registry |
Choose UptimeRobot if
- You need to watch many endpoints, or check every 30 seconds.
- You want a public status page for customers.
- You need SMS or voice alerts out of the box.
- Uptime is the whole question, and someone already knows who holds every login.
Choose Stackbrace if
- You look after sites built by other people, and the first question in an outage is who to call.
- You want the renewal, the login and the backup recorded somewhere that checks itself.
- You want security holes, faked email and hijack signs watched daily, not only uptime.
- An agency handing a client a record of their site, not only a green light.
Using both
Plenty of agencies run both: UptimeRobot for the 30-second checks and the status page, Stackbrace for the record and the alert that names a person. Stackbrace’s webhook can post into the same channel.
