If you search for uptime monitoring tools, you get a sea of affiliate posts that rank everything 9.5/10 and recommend whatever pays the highest commission. This is not that.
Below is a detailed breakdown of the six tools I looked at closely: Uptiqr, UptimeRobot, BetterUptime, StatusCake, Pingdom, and Oh Dear. I tested each one, checked the actual pricing pages (not the marketing copy), and noted where the free plans have quiet limits that bite you later.
Quick comparison
| Tool | Free monitors | Free check interval | Status pages | On-call / escalation | Starting paid price |
|---|---|---|---|---|---|
| Uptiqr | 10 | 3 min | Yes (included) | No | $9/mo |
| UptimeRobot | 50 | 5 min | Yes (branded) | No | $7/mo |
| BetterUptime | 10 | 3 min | Yes (included) | Yes | $20/mo |
| StatusCake | 10 | 5 min | Yes (branded) | No | $24.99/mo |
| Pingdom | 0 | N/A | No | Yes | $15/mo |
| Oh Dear | 0 | N/A | Yes (included) | No | $17/mo |
A few things this table does not capture: how good the alerts actually are, how much setup friction there is, and where each tool's edge cases break down. That is what the rest of this article covers.
Uptiqr
Uptiqr is the newest tool on this list, launched in mid-2026 after Freshping shut down. The free plan gives you 10 monitors at 3-minute intervals, email alerts, and public status pages -- no branding on the free tier, which is rare.
What it does well: The status page setup is fast and the UI is clean. Heartbeat monitoring (for cron jobs and background workers) is included on all plans, which most tools charge extra for. SSL certificate monitoring is also built in.
Where it falls short: No on-call scheduling or escalation policies. If you need PagerDuty-style rotation across a team, you will need a separate tool. Multi-location checks are on paid plans only. It is also new, so there is less community documentation compared to UptimeRobot.
Pricing: Free tier is genuinely usable. Starter is $9/mo for 25 monitors at 1-minute intervals. Pro is $19/mo for 50 monitors with team seats.
Best for: Solo developers and small SaaS teams who want solid monitoring without paying $20+/month.
UptimeRobot
UptimeRobot has been around since 2010 and is the default recommendation for "free uptime monitoring" -- 50 monitors on the free plan is hard to beat. The catch is the 5-minute check interval.
What it does well: The free plan is genuinely the most generous by monitor count. The API is well-documented and there are integrations for everything (Slack, PagerDuty, Telegram, webhooks). It is reliable -- I have not seen reports of the monitoring service itself going down.
Where it falls short: 5-minute checks mean a 4-minute outage might go completely undetected. Their status pages on the free tier show "Powered by UptimeRobot" branding. The UI feels dated in 2026. Paid plans jump to $7/mo for 1-minute intervals across 50 monitors, which is reasonable, but you still get UptimeRobot branding on status pages unless you pay more.
Pricing: Free forever for 50 monitors at 5-min intervals. Solo plan at $7/mo removes branding and adds 1-minute checks.
Best for: Anyone who needs to monitor a lot of URLs and does not have strict latency requirements on detection time.
BetterUptime
BetterUptime is the most polished tool in this comparison and the most expensive. Their differentiator is the on-call calendar: you can set up rotation schedules so alerts go to whoever is on duty, with escalation if they do not respond.
What it does well: The on-call scheduling is genuinely well-built -- comparable to PagerDuty at a fraction of the cost. Status pages are clean and include incident timelines. The free plan is competitive: 10 monitors, 3-minute intervals, and on-call scheduling included.
Where it falls short: Pricing scales quickly if you have a larger team. The $20/mo starting price is fine for a small team but gets expensive fast. Some features that competitors include by default (like heartbeat monitoring) are locked to higher plans.
Pricing: Free plan has 10 monitors. Hobby plan is $20/mo, which includes 1-minute checks and unlimited team members on the on-call rotation.
Best for: Teams that need proper incident escalation and on-call rotation. If you are solo or a 2-person team, the on-call features are overkill.
StatusCake
StatusCake has been around since 2012 and covers the basics well. Their free plan gives you 10 monitors at 5-minute intervals, and paid plans add page speed monitoring and domain/SSL expiry alerts as distinct features.
What it does well: Page speed monitoring is a nice addition -- it tracks Core Web Vitals alongside uptime, which the other tools on this list do not. SSL and domain expiry monitoring are explicit, well-organized features rather than afterthoughts.
Where it falls short: The 5-minute interval on the free plan is the same problem as UptimeRobot. The paid plans start at $24.99/mo, which is hard to justify over BetterUptime unless you specifically need the page speed features. The UI is serviceable but not great.
Pricing: Free for 10 monitors at 5-min. Core plan at $24.99/mo for 100 monitors with 1-minute intervals.
Best for: Teams that care about page speed data alongside uptime, or who are already in the StatusCake ecosystem.
Pingdom
Pingdom is the enterprise option on this list. There is no free plan. You start at $15/mo and get real user monitoring (RUM) alongside synthetic uptime checks -- which is genuinely useful for understanding how real users experience your site, not just whether it responds to a ping.
What it does well: Real user monitoring is the standout. Pingdom injects a small script into your pages and collects actual load times, geographic distribution, and browser breakdowns from real visitors. No other tool on this list does this. The uptime monitoring itself is also multi-region by default.
Where it falls short: It is expensive relative to what you get if you only need basic uptime monitoring. The UI has improved but still feels like it was built for an enterprise procurement process. No free plan makes it hard to evaluate without a credit card.
Pricing: Starts at $15/mo for 10 uptime checks + RUM on up to 100k monthly page views.
Best for: Established products where you want to understand real user performance, not just whether the server is up.
Oh Dear
Oh Dear is the most opinionated tool on this list, in a good way. It focuses on a specific set of features -- uptime, broken link crawling, certificate monitoring, and scheduled task monitoring -- and does all of them well.
What it does well: The broken link crawler is unique. Oh Dear will crawl your site and alert you when internal or external links break, which is genuinely useful for content-heavy sites. The UI is clean and the documentation is thorough. Certificate and domain monitoring are first-class features, not checkboxes.
Where it falls short: No free plan. $17/mo for 5 sites, which is fine if you have multiple properties to monitor. If you only have one site, the pricing is harder to justify. No on-call scheduling.
Pricing: Starts at $17/mo for 5 sites. Pricing is per site, not per check.
Best for: Agencies or founders managing multiple sites who want broken link monitoring alongside uptime.
How to choose
The honest answer is that it depends on one question: do you need on-call scheduling?
If yes, use BetterUptime. Nothing else on this list does it as well at a comparable price.
If no, the decision comes down to monitor count vs. check frequency:
- Need to monitor 50+ URLs on a budget: UptimeRobot free plan
- Need 1-minute checks with clean status pages and no branding: Uptiqr or BetterUptime
- Need page speed data alongside uptime: StatusCake
- Need real user monitoring: Pingdom
- Need broken link crawling across multiple sites: Oh Dear
Tip
If you are just starting out, UptimeRobot and Uptiqr both have usable free plans. Start with one of those. Upgrade when your monitoring requirements outgrow the free tier -- not before.
Setting up heartbeat monitoring
Most developers monitor their HTTP endpoints but forget about background jobs. A cron that silently fails is just as bad as a site that goes down. Heartbeat monitoring catches this.
The pattern is simple: your cron job sends a GET request to a unique URL after it finishes. If the monitoring tool does not receive that ping within your expected interval, it fires an alert.
# Example: ping your heartbeat URL after a successful cron run
0 * * * * /path/to/script.sh && curl -s https://your-monitor-url/heartbeat/abc123
Most tools on this list support this -- UptimeRobot calls them "keyword monitors", BetterUptime calls them "heartbeat monitors", Uptiqr has a dedicated heartbeat tab in the monitor creation form.
Frequently asked questions
What is a good uptime percentage?
99.9% uptime ("three nines") allows about 8.7 hours of downtime per year. 99.99% allows about 52 minutes. For most SaaS products, 99.9% is the realistic target. Major cloud providers typically guarantee 99.95% to 99.99% at the infrastructure level, but your application can still go down even when the underlying infrastructure is up.
How often should I check my site?
1-minute intervals are the standard for production services. 5-minute intervals will miss short outages. If your site processes payments or runs real-time features, 1 minute is the right cadence.
Do I need monitoring on my staging environment?
Usually not. Staging environments go down intentionally during deploys and tests. Monitoring them creates alert noise. Monitor production and any environment that real users touch.
What is the difference between uptime monitoring and real user monitoring?
Uptime monitoring (synthetic monitoring) checks your site from an external server on a schedule. It catches infrastructure-level failures. Real user monitoring (RUM) collects data from actual user browsers -- load times, errors, geographic performance. They are complementary: uptime monitoring tells you if the site is up, RUM tells you how fast it is for real users.
Should I use a paid tool or a free one?
Start free. UptimeRobot and Uptiqr both have genuinely useful free plans. Move to paid when you need 1-minute intervals, custom status pages without branding, or on-call scheduling. Do not pay for features you will not use.
