UptimeRobot vs Uptrends

UptimeRobot The default cheap HTTP monitor: many checks, a status page, and a free tier people actually use. Uptrends Browser-level synthetics and API checks, including multi-step payments and OpenTelemetry export. UptimeRobot is uptime checker. Uptrends is synthetics / mid-market. The shared word is “monitoring.” The products are not substitutes. If you only needed a public status page and a health check, neither may be the smallest tool — GreenCrew is built for that job.

Side by side

Topic	UptimeRobot	Uptrends
Best for	Teams that want a lot of URL checks, keyword monitors, and a familiar status page without a sales call.	Teams that need to prove a user journey — not just a URL — from many regions, and maybe stream that into OTel.
Not for	Anyone who needs browser transactions, APM, or a status page that can be overwritten when HTTP is lying.	A first monitor on a side project, or anyone who only wanted a public status URL.
Hosting	Hosted	Hosted
What it checks	HTTP(S), ping, port, keyword, and heartbeat checks. Free tier is 5-minute intervals.	Transaction monitoring in real browsers, API steps, extra confirmations that a payment actually landed.
Status page	Hosted public status pages, custom domains on paid plans.	Reporting and public dashboards; the product is the probe, not the customer page.
Alerts	Email, SMS, Slack, Telegram, Discord, webhooks, and more.	Detailed synthetic failures, including which step broke.
Complexity	Simple	Moderate
Pricing shape	Free tier, then inexpensive paid plans as monitor count grows.	Priced as synthetics, not as a free ping. Transactions cost more than availability.
