Free uptime monitoring: what you get and what it costs you

"Free uptime monitoring" is one of the most searched phrases in this entire category, and for good reason. If checking your site costs nothing, why would anyone pay at all. The honest answer is that free plans are real and useful, but they are built to get you in the door, and their limits are chosen carefully. This article walks through what you actually get for free, what it quietly costs you, and when a free plan really is enough.

What a typical free plan gives you

The best-known free plan is from UptimeRobot, so it makes a fair benchmark. As of 2026 it offers:

• 50 monitors with a check interval of 5 minutes
• HTTP/HTTPS and a few other basic check types
• email alerts
• a basic public status page
• personal, non-commercial use only (this restriction was added in late 2024)

That is a lot of monitoring for zero euros, and for a hobby project or a personal blog it is often plenty. Other tools, like Better Stack, also offer free plans (around 10 monitors), and open-source solutions like Uptime Kuma are free forever if you run them yourself.

What it actually costs you

Free plans are free because they limit exactly the things that matter most when something is really on fire. Four common limits:

1. Check interval

Most free plans check every 5 minutes. That sounds fine until you do the math: a 5-minute interval means an outage can run for up to 5 minutes before the first check even notices it, plus the time to retry. Fine for a personal site. For anything where minutes of downtime cost money or trust, a 1-minute interval is a different product.

2. History and data retention

Free plans keep only a short, often vague window of history. You usually cannot pull a clean uptime percentage for the last 90 days or hand a report to a client. When you need a number for an SLA or a timeline after an incident, the data simply is not there.

3. No SSL, SLA or advanced checks

The features that prevent the most embarrassing outages are exactly the ones behind paid plans: alerts for SSL certificate expiry (one of the leading causes of "the site is down" panic), DNS checks, keyword or content checks, and SLA reports.

4. Alerting that wakes you up

Free plans alert by email. Email is easy to miss. Higher delivery confidence comes from instant channels like Telegram, Slack, Discord or Microsoft Teams - an alert that actually reaches a person at three in the morning. (SMS and phone calls are offered by some other tools for an extra fee.)

A quick reality check

Where ePulz.io stands - honestly

We will say it straight: ePulz.io does not have a forever-free plan. We chose not to offer one, because a credible free plan usually means a crippled interval, no real alerting and a product that quietly pushes you toward an upgrade. We would rather not run monitoring we would not trust ourselves.

Instead, we offer a 7-day free trial with no payment card. For a week you get the whole product: 12 monitor types, checks from three independent EU probes with 2-of-3 consensus, so a flicker in connectivity does not wake you, intervals down to 1 minute, SSL expiry alerts and SLA-grade history. After the trial, paid plans start at 4 EUR/month (Standard), Profi at 9 EUR and Business at 27 EUR.

We are also EU-hosted and GDPR-compliant, which matters if the residency of your data is not optional.

So, should you use free monitoring

Yes, if:

• it is a personal or hobby project
• 5-minute detection and email alerts are acceptable
• you do not need SSL alerts, SLA reports or long history

Move on from the free plan when downtime starts to cost you money, reputation or a client relationship. At that point those few euros a month are not a cost, they are insurance.
