Pricing Comparison

The biggest difference between UptimeSignal and UptimeRobot is pricing structure. UptimeRobot uses per-monitor pricing on paid plans, which means your bill grows with your infrastructure.

UptimeRobot Pricing Tiers

UptimeSignal Pricing

$15/month for unlimited monitors. Always.

Monitor 10 endpoints or 1,000 — same price. Your monitoring costs don't scale with your infrastructure.

Example: A Growing SaaS

Imagine you're running a SaaS with an API, main app, marketing site, staging environments, and third-party integrations. You might need 75-100 monitors.

UptimeRobot $30/month
UptimeSignal $15/month

That's $180/year in savings — enough to pay for another year of monitoring.

Free Tier Commercial Use

In October 2024, UptimeRobot updated their terms of service to explicitly prohibit commercial use on their free tier. From their FAQ:

"The free plan is only for personal, non-commercial use. If you're using monitoring for a business, commercial project, or any application that generates revenue, you need a paid plan."

This affects a lot of developers:

UptimeSignal allows commercial use on all plans

Including the free tier. Run a business, have a side hustle, monetize your project — we don't restrict how you use your monitors.

What UptimeRobot Does Well

We're not here to trash the competition. UptimeRobot has been around since 2010 and has earned its reputation. Here's where they shine:

14+ years of reliability

They've been doing this longer than most. That's a proven track record.

More alert channels

UptimeRobot supports SMS, phone calls, and more integrations than UptimeSignal currently offers.

Longer history retention

UptimeRobot keeps 2 years of history on paid plans. UptimeSignal keeps 90 days.

More monitors on free tier

50 monitors vs our 25. Though theirs can't be used commercially.

Where UptimeSignal Wins

Flat pricing, not per-monitor

$15/month gets you unlimited monitors. Monitor 10 endpoints or 1,000 — same price. Your bill doesn't scale with your infrastructure. This is the pricing model developers actually want.

Commercial use on free tier

Use it for your side project, your startup, your client work. We don't care how you make money. The free tier is for trying us out and for small projects, regardless of whether they're commercial.

Modern, focused interface

UptimeRobot has been around since 2010, and the interface shows its age. UptimeSignal is built with modern tech (React, Tailwind) and focuses on what matters: your monitors and their status.

Magic link authentication

No passwords to remember or manage. Click a link in your email and you're in. Simple and secure.

Unlimited status pages included

Create as many public status pages as you need on any plan. Share your uptime with customers without extra cost.

Switching is straightforward. There's no complex import process — just add your URLs and you're monitoring within minutes.

Sign up for UptimeSignal

Create an account at app.uptimesignal.io. No credit card required. We'll send you a magic link to log in.

2

Add your monitors

Add the same URLs you're monitoring in UptimeRobot. You can copy them from your UptimeRobot dashboard. Each monitor takes about 10 seconds to set up.

3

Run both services in parallel (optional)

Keep UptimeRobot running while you test UptimeSignal. Once you're confident everything is working, you can cancel UptimeRobot.

4

Set up status pages (optional)

If you're using UptimeRobot's status pages, create equivalent ones in UptimeSignal. Then update your DNS or links to point to your new status page URL.

Tip: You don't need to migrate all at once. Start with your most critical monitors, verify they're working, then add the rest. There's no rush.
