The comparison
Your website can stop working while you're helping a customer, finishing a project, or asleep. Most owners find out the worst way possible: a customer emails to say "your site is down." An uptime monitoring tool fixes that. It visits your site on a schedule, from servers around the world, and alerts you the moment something breaks.
Think of it as a lookout posted on the castle wall. It can't stop the dragon, but it can make sure you hear about it before the villagers do.
This guide compares seven services, from free starter plans to tools that can test a full checkout or login.
How we compared: This is a research-based guide, not a hands-on test. We reviewed each company's published pricing and feature pages. Prices and plan details were checked on November 6, 2026, and they change often, so confirm on the vendor's site before you buy. Prices are in US dollars unless noted.
The tools are listed alphabetically, not ranked.

"Fastest checks" is the shortest interval any plan offers, not what the cheapest plan includes. Details and sources follow below.
1. Better Stack
Good fit: Teams that need the right person to actually respond
Detecting an outage is half the job. Better Stack focuses on the other half: getting a human out of bed. It bundles uptime checks with on-call scheduling, phone and SMS alerts, and incident timelines.
What you get:
- Free: 10 monitors and heartbeats, one status page, Slack and email alerts, with checks every 3 minutes
- Paid: checks as often as every 30 seconds, error screenshots, multi-location checks, and multi-step incident verification before alerting
- Unlimited phone-call and SMS alerts for each paid "responder"
- Optional browser-based transaction checks that click through your site like a real visitor
Pricing snapshot: A responder license is $29/mo billed yearly ($34 monthly). Extra monitors are sold in blocks of 50 for $21/mo yearly. Extra status pages and branding options cost more. Team members who don't need to respond to alerts are free. Better Stack offers a 60-day money-back guarantee.
Pros: Strong incident features for the price. Error screenshots and confirmation from multiple locations help you understand an outage fast.
Keep in mind: The pricing is built from parts (responders, monitor blocks, status-page add-ons), so add up your real setup before comparing. Its free plan is labeled for personal projects. For a one-person shop with two websites, this may be more platform than you need.
2. HetrixTools
Good fit: Free one-minute monitoring, especially if you run your own server
HetrixTools offers the fastest free checks on this list: 15 monitors checked every minute. It only declares an outage when most of your selected locations agree, which helps cut false alarms.
What you get:
- Free: 15 uptime monitors and 15 server monitors, 1-minute checks from 4 of its 12 locations, public status pages, SSL and domain-expiry alerts, nameserver change alerts, and maintenance windows
- Alerts to email, Slack, Microsoft Teams, Discord, Telegram, webhooks and more on every plan (SMS and phone calls use paid credits)
- A free server agent for Linux, Windows, macOS and shared hosting that tracks CPU, memory, disk and drive health
Pricing snapshot: Professional is $9.95/mo for 30 monitors and 6 locations. Business is $19.95/mo for 60 monitors, 9 locations and full white-label reports. Enterprise is $49.95/mo for 200 monitors and all 12 locations. Yearly billing gets roughly two months free.
Pros: Excellent value. Features that others reserve for paid tiers, like SSL checks and status pages, are free here.
Keep in mind: Free accounts must log in at least once every 90 days to stay active. One minute is the fastest interval on any plan. The free plan has no team sub-accounts, and free-tier support is slower than paid. Server metrics require installing the agent; website checks don't.
3. Mage Watcher (our product)
Good fit: Agencies and teams that want fewer false alarms and no per-user fees
Mage Watcher checks websites, servers and APIs from several geographic regions. Before it calls something an outage, a second region has to confirm the failure. That's designed to filter out the "it's only broken from one data center" blips that can wake you up for nothing.
What you get:
- Multi-region confirmation: at least two regions must agree before an incident opens
- Email incident alerts, incident history and response-time reporting
- Image Capture: a screenshot of the failing page, so you can see what visitors saw
- Unlimited users on every plan, with no per-seat pricing
Pricing snapshot:
- Starter: $19/mo, or $190/year, for 10 monitors. Screenshots are a $10/mo add-on.
- Professional: $49/mo, or $490/year, for 50 monitors, with screenshots on every incident and 5 GB of screenshot storage.
- Agency: $99/mo, or $990/year, for 200 monitors and 25 GB of storage.
- Extra monitors and extra monitoring regions can be added as monthly "pods."
Pros: Unlimited users is genuinely useful for agencies sharing access with staff or clients. Screenshot evidence helps when you need to show a client (or a host) what went wrong.
Keep in mind: There's no free plan. The product page lists email as the alert channel and doesn't publish a check interval, SMS or chat-app alerts, or status pages, so ask before you buy if you need any of those. At $19 for 10 monitors, the entry price is higher than several competitors' free tiers.
4. Pingdom
Good fit: Online stores and booking sites where the checkout has to work
A website can be "up" while its checkout, login or booking form is broken. Pingdom, owned by SolarWinds, is known for transaction monitoring: it can walk through steps like adding to cart or signing in, and alert you when the path fails.
What you get:
- Uptime checks every minute, page-speed monitoring and email/SMS alerts
- Transaction (multi-step) checks, which Pingdom calls advanced checks
- Optional Real User Monitoring (RUM), which measures how fast pages load for actual visitors
Pricing snapshot: Pingdom doesn't use named plans. You pick a quantity on a pricing calculator. Recent third-party readings of that calculator put the entry Synthetic Monitoring tier at about $18/mo, or about $16.50/mo billed yearly, for 10 uptime checks, 1 advanced check and 50 SMS credits. Real User Monitoring is priced separately by page views. There's a free trial but no ongoing free plan.
Pros: A long track record and solid transaction monitoring for sites where one broken step costs real money.
Keep in mind: The entry tier includes only one advanced check, so monitoring several customer journeys pushes you up the price ladder quickly. Synthetic monitoring (robots testing your site) and RUM (data from real visitors) are separate products with separate bills, so be sure which one you need.
5. StatusCake
Good fit: Keeping an eye on more than whether the homepage loads
StatusCake bundles several types of checks into one account: uptime, page speed, SSL certificates, domain expiry, and (on paid plans) server health. That's handy when your real fear isn't the site going down, but the certificate quietly expiring on a Saturday.
What you get:
- Free: 10 uptime monitors at 5-minute intervals, plus 1 page-speed, 1 domain and 1 SSL monitor
- Superior: 100 uptime monitors at 1-minute intervals, 15 page-speed monitors, 50 domain and 50 SSL monitors, 3 server monitors, 75 SMS credits a month, reporting
- Business: 300 uptime monitors at 30-second intervals and 9 team members
Pricing snapshot: Superior is $20.41/mo billed yearly ($24.49 monthly). Business is $66.66/mo billed yearly ($79.99 monthly). Paid plans offer a 7-day free trial.
Pros: A lot of monitors for the money on Superior. SSL and domain checks are built in, not bolted on.
Keep in mind: The free plan's extra checks are slow: SSL and page speed run once a day, domain checks once a week. Superior includes just one team member, so shared access means stepping up to Business.
6. Uptime.com
Good fit: Businesses that rely on several connected services and need reports to prove it
Uptime.com covers a wide range of checks: websites, APIs, email servers, DNS, transactions and page speed. It also offers SLA reporting, which is useful if you owe clients proof of uptime.
What you get:
- 1-minute checks from a network of more than 100 probe servers
- Uptime, transaction, API and page-speed monitoring under one Website Monitoring plan
- Email and SMS alerts with more than 20 integrations
- Unlimited users and 24 months of check history
- Real User Monitoring and status pages as add-ons
Pricing snapshot: Website Monitoring starts at $9/mo billed yearly ($108/year). A calculator raises the price as you add checks. There's no free plan, but new customers get a 30-day money-back guarantee. Discounts are available for nonprofits and schools.
Pros: Broad check types and strong reporting. Unlimited users on every plan.
Keep in mind: The $9 starting point covers a small bundle of checks, and costs climb as you add more. A simple brochure website may use only a sliver of what you're paying for.
7. UptimeRobot
Good fit: Owners who want a lot of monitors for free
UptimeRobot is one of the best-known names in uptime monitoring, and its free plan is the most generous on this list for sheer quantity: 50 monitors checked every five minutes.
What you get:
- Free: 50 monitors (website, port, ping and keyword checks) every 5 minutes, one basic status page, and 3 months of history
- Solo: 10 or 50 monitors with 60-second checks, plus SSL and domain-expiry alerts, multi-location checks, Slack alerts and 3 status pages
- Team: 100 monitors, 30-second checks, 3 login seats
- Scale: 200 or 500 monitors with 15-second checks
Pricing snapshot: UptimeRobot's pricing page varies by region. Recent US price checks put Solo at about $12/mo billed yearly ($13 monthly) and Team at about $39/mo billed yearly. Paid plans come with a 14-day money-back guarantee.
Pros: Hard to beat at $0. Quick to set up. A good "is it on?" safety net for a handful of small sites.
Keep in mind: Five-minute checks mean an outage can run a few minutes before you hear about it. The free plan leaves out SSL certificate and domain expiry alerts, maintenance windows and multi-location checks. Oddly, the entry Solo plan includes fewer monitors (10) than Free (50); you're paying for speed and features, not quantity. UptimeRobot positions Free for personal projects, so read the current terms if you're monitoring a business site.
What should you look for?
Five questions do most of the work:
- How often does it check? A 5-minute interval means up to 5 minutes of downtime before you know. For a store or booking site, 1 minute or faster is worth paying for.
- Does it confirm failures? Tools that re-check from other locations before alerting send fewer false alarms. Every false alarm makes you a little more likely to ignore the next real one. Ask the boy who cried "500 error."
- How will alerts reach you? Email is fine for a hobby site. If downtime costs you sales, pick a tool that can text, call or post to the chat app you actually watch.
- What counts as one "monitor"? Your homepage, checkout page, API and SSL certificate may each use a separate monitor. Count before you compare.
- What will the full setup cost? Add up extra users, SMS credits, status pages, screenshots and add-ons, not just the headline price.
Questions people ask
My web host already monitors my server. Do I still need this?
Probably. Your host watches its equipment. An outside monitor watches what your visitors see, including problems your host may not count as "down," like an expired certificate or a broken plugin showing an error page.
Will monitoring slow my website down?
No. A check is a single lightweight visit, like one extra visitor every minute or so. Your site won't notice.
Is a free plan good enough?
For a personal site or a small brochure site, often yes. If an hour of downtime costs you real money, the faster checks and better alerts on a paid plan usually pay for themselves.
What's the difference between uptime monitoring and transaction monitoring?
Uptime monitoring asks "does the page load?" Transaction monitoring asks "can a customer actually finish buying something?" The second is more useful for stores, and more expensive.
What's a status page?
A public page showing whether your services are working. It saves you from answering the same "is it down?" email 40 times during an outage.
Which should you choose?
- Free, fast checks: Start with HetrixTools (15 monitors at 1 minute).
- The most free monitors: UptimeRobot (50 monitors at 5 minutes).
- Fewer false alarms and unlimited users for an agency team: Consider Mage Watcher, keeping in mind it's our product and confirming its alert options fit your needs.
- Getting the right person to respond: Better Stack.
- Uptime plus SSL, domain and speed checks in one bill: StatusCake.
- Making sure the checkout works: Pingdom or Uptime.com.
Whichever you pick, start with two monitors: your homepage and your most important customer action, like a contact form or checkout. Then make sure the alerts go to someone who can do something about them. A monitor that emails an inbox nobody reads is just a very polite smoke detector with the battery removed.
