Quick answer
UptimeRobot - UptimeRobot wins for most builders because its free tier is broader and stays free for real multi-monitor use, while DigitalOcean Uptime is better only if you want a very simple one-monitor setup inside the DigitalOcean stack.
How the free tiers compare
These products solve the same basic job, but the free tiers are aimed at different kinds of builders. DigitalOcean Uptime is the smaller, simpler offer: one free uptime monitor, four monitoring regions, 1-minute checks, Slack/email alerts, and then $1 per added monitor. It is easy to understand, but the free tier is tightly capped and the paid path is purely per monitor. UptimeRobot gives you much more room to grow before paying: up to 50 monitors, 5-minute checks, multi-location monitoring, basic status pages, API access, and limited integrations, with no credit card required on free. If you want to monitor several endpoints before committing, UptimeRobot is the better free-tier starting point. If you only need a single extra-simple check and may already be in DigitalOcean, DigitalOcean Uptime is the leaner fit.

|---|---|---|
| Free monitorsA is tightly capped; B allows broad free usage. | 1 uptime monitor per month | Up to 50 monitors |
| Monitoring intervalB's faster 60-second checks are on paid plans. | 1-minute interval performance checks | 5-minute monitoring intervals |
| Monitoring regions / locationsB does not specify a free-tier region count in the input. | 4 monitoring regions | Multi-location monitoring |
| Alerts / integrationsA describes alerts per check; B limits integrations on free. | Up to 5 configured alerts per check | Up to 5 integrations |
| Data retentionB includes a stated retention window on free. | Not specified | 3 months of data retention |

After you outgrow the free tier
DigitalOcean Uptime uses simple per-unit pricing after the free tier: $1 per additional monitor per month. That makes costs scale linearly with the number of checks, and it stays cheap for tiny setups. UptimeRobot uses flat paid tiers for most customers: Solo at $8/month, Team at $34/month, and Enterprise starting at $64/month. That means B costs more once you leave the free tier, but you get far more included monitors and collaboration features. Based on the provided rates, DigitalOcean is cheaper for very small paid usage, while UptimeRobot is better value when you need many monitors and seats.
Cost at real usage
| Usage | DigitalOcean Uptime | UptimeRobot |
|---|---|---|
| 1 additional monitor beyond the free allowanceB remains free as long as total monitors stay within the free cap. | $1/mo | Free (within 50-monitor free tier) |
| 5 monitors totalA is estimated from $1 per added monitor; B still fits free tier. | ~$5/mo | Free (within 50-monitor free tier) |
| 10 monitors totalB's free tier still covers this; A scales per monitor. | ~$10/mo | Free (within 50-monitor free tier) |
| 60 monitors totalB would need a paid plan, but the input does not provide a direct overage formula between tiers. | ~$60/mo | $8/mo at minimum paid tier |

- You already use DigitalOcean and want monitoring close to your hosting workflow.
- You expect to add monitors one at a time and are fine paying $1 per additional monitor.
- Your main need is basic email or Slack alerts on a small number of endpoints.
Pick UptimeRobot when…
- You want to monitor several websites, APIs, or endpoints before paying anything.
- You need API checks, DNS checks, SSL checks, or domain expiration monitoring on the free tier.
- You want basic status pages and API access without moving to a paid plan.
- You prefer a no-credit-card-required free tier for trialing monitoring across a larger set of services.
- You expect to outgrow a tiny cap quickly and want room to scale into paid plans later.
Bottom line
For the most common builder case, UptimeRobot is the better free-tier pick because it lets you monitor a real set of services before you pay, and it includes useful extras like API access and basic status pages. DigitalOcean Uptime is only the better choice if your monitoring needs are tiny, you want a very simple per-monitor price, or you specifically want to keep monitoring inside DigitalOcean. Once you need more than a couple of checks, UptimeRobot gives you more room to grow.
