UptimeRobot is the default answer to "how do I know when my site goes down?" — and deservedly so. The free tier (50 monitors at 5-minute intervals) is one of the most generous in SaaS, setup takes ninety seconds, and it checks your sites from multiple locations around the world.
The squeeze starts when you outgrow free: 1-minute intervals, more monitor types, proper status pages and longer log retention all live behind the paid tiers at roughly $8/month and up — $96+/year, forever, with monitor counts still capped. If you run client sites and own even one $5 VPS, there is a pay-once path: Upwatch, $39, unlimited monitors, your own branded status page.
What UptimeRobot does well
UptimeRobot has earned its two million users:
- A genuinely useful free tier — 50 monitors free is unmatched.
- Multi-location checking, so one flaky network route does not page you at 3 a.m.
- Broad monitor types: HTTP, ping, port, keyword, SSL expiry, cron/heartbeat.
- Mature integrations — Slack, PagerDuty, Telegram, SMS and voice calls on paid tiers.
If you monitor three personal projects and the free tier covers you, honestly: keep it. Free wins.
Where the subscription model hurts
The paid math is where agencies feel it. The Solo tier runs about $8/month — $96/year, $480 over five years — and still caps monitors at 50. Monitoring 80 client sites means a higher tier and a forever-growing bill that scales with your success. The polished status pages, longer retention and faster checks are all rungs on the same ladder, and every rung renews annually.
Your monitoring data also lives in their cloud, attached to their account limits. Want a fully branded status page on your own domain with your own retention policy? That is exactly the feature set the pricing ladder is built to sell you, one tier at a time.
Upwatch: the pay-once alternative
Upwatch is a $39, one-time purchase. Self-hosted uptime monitoring + a beautiful public status page. Upwatch was built for the agency case: unlimited HTTP(S) monitors with status-code and keyword assertions, per-monitor uptime stats and incident logs, Slack/Discord-compatible webhooks plus SMTP email on down and recovery, and a classic 90-day-bar public status page at /status.
The source code is MIT-licensed at github.com/bensblueprints/uptime-monitor — free to build and run yourself, forever. Buying the packaged version on Whop gets you the signed installer, 1-click setup and updates. Either way, there is no account, no telemetry and no renewal date.

Who should stay with UptimeRobot
Stay with UptimeRobot if the free tier covers you — do not pay $39 to replace $0. Stay if you need multi-region checking (Upwatch checks from the one box you run it on), ping/port/DNS monitor types, or SMS/voice alerting managed for you.
Switch if you are an agency or indie host paying monthly to watch client sites. One $5 VPS runs Upwatch with unlimited HTTP monitors, 30-second intervals, keyword checks and a clean branded status page for every client — for a flat $39, once.
Making the switch
Step 1 — Buy once on Whop. One-time $39 for the packaged, zero-config version with updates and priority support.
Step 2 — Run it anywhere. Desktop app for personal use, or docker compose up on a $5 VPS for a public status page.
Step 3 — Add monitors, get alerts. HTTP checks every 30s, webhook/email pings the second something breaks — and again when it recovers.
Common questions
Is it really free on GitHub?
Yes — MIT source at github.com/bensblueprints/uptime-monitor, always. The paid version is pure convenience: packaged installer, updates, priority support.
Do I need a server?
Not necessarily. Desktop mode runs the whole app in an Electron window. For a public status page or 24/7 monitoring you'll want a $5 VPS — which is still cheaper per year than one month of most competitors' higher tiers.
What check types are supported?
HTTP(S) with status-code and keyword assertions. No ping/port/DNS checks yet — if you need those today, UptimeRobot still has the broader check menu.
The bottom line
Subscriptions make sense when a service does ongoing work for you — hosting, syncing, multi-region infrastructure, human labor. They make much less sense when the work happens on your own hardware and the monthly bill is just a toll booth. Upwatch is our bet that for this job, most people are better served owning the tool: $39 once, pays for itself vs UptimeRobot in under 5 months — then it's free forever.
Upwatch is part of OneTimeSuite — 56 desktop and self-hosted apps built on the same principle: your hardware does the work, so you should not pay rent on it. Every app is a one-time purchase with MIT-licensed source on GitHub, no accounts and no telemetry. Want everything at once? OneTimeSuite Complete bundles the whole suite for a single flat $997.
