Watchdroid Comparison
Free uptime monitoring compared — UptimeRobot, Better Stack, Healthchecks.io, StatusCake and Uptime Kuma vs our Watchdroid monitors: monitor counts, check intervals, heartbeat/cron support, alerts and status pages.
All six services can be used for free — the differences are in how much monitoring that actually buys. Watchdroid swaps the usual monitor cap for none at all, and checks every minute instead of every five.

Which one should you pick?
- Watchdroid: The only free tier here with 1-minute checks and no monitor cap — plus the rare combo of HTTP checks, cron heartbeats with run-time tracking, SSL expiry alerts and a public status page in one account. Best when you want full monitoring without a bill.
- UptimeRobot: The biggest hosted free plan by raw count: 50 monitors at 5-minute intervals and five alert integrations. Brief sub-5-minute outages can slip through, and heartbeat monitors are paid-only.
- Better Stack: The most polished option — error screenshots and incident timelines even on free — but only 10 monitors, 3-minute checks, and the free tier is labeled for personal projects.
- Healthchecks: The cron-monitoring specialist: period + grace or cron expressions, start/finish pings, and it is open source. No website checks and no status pages — pair it with an uptime monitor.
- StatusCake: The broadest free monitor-type mix — you get one SSL, domain and page-speed test alongside 10 uptime checks. 5-minute intervals and no free status page.
- Uptime Kuma: Unlimited monitors, 20-second checks and 90+ notifiers for $0 — if you run it yourself. You pay with a server and your own maintenance; when the host dies, so do your alerts.
