How the free plans compare
Free tiers as published mid-2026 — each has a different strength; verify current terms with each vendor.
| Free tier | Monitors | Interval | Regions per check | Commercial use | First paid tier |
|---|---|---|---|---|---|
| FourSight | 10 | 5 min | 4 (quorum consensus) | Allowed | $16/mo (Starter) |
| UptimeRobot | 50 | 5 min | single location | Positioned non-commercial (2025 policy) | ~$8/mo (Solo) |
| Better Stack | 10 | up to 30 sec | not published as consensus | Aimed at personal projects | ~$25/mo |
The honest read: UptimeRobot's free tier has the most monitors, Better Stack's checks the fastest, and FourSight's is the one that allows commercial use and validates every check from four regions before alerting. Details in the pricing comparisons.
