Every European uptime monitoring software tool reviewed
Berlaar, Belgium
Founded 2018
Starts at $17 a month for 2 sites or servers and reaches $439 a month at 200; custom Enterprise quotes; annual billing saves two months
Demo on request
Best for: Web agencies and lean teams looking after customer sites who prefer a single monitor for availability, certificates and dead links
Oh Dear grew out of the client work of two Belgian developers from the Spatie team, Freek Van der Herten and Mattias Geniar, and one monitor reflects that: it tests availability from several places, watches when a certificate lapses, crawls for dead links and mixed content, tracks DNS and domain expiry, and follows scheduled tasks. An agency avoids stitching three small services together.
The legal entity is Immutable VOF in Berlaar, active since 2018. Combell, a host with ISO 27001 certification, holds the primary data, and ClickHouse Cloud is a second sub-processor for performance metrics. Pricing begins at $17 monthly for two sites or servers and tops out at $439 for 200; the trial lasts 10 days without a card. The scope is narrow: there is no tracing, infrastructure metric or self-hosted version.
What Oh Dear does well
- One monitor covers availability, certificate expiry, dead links and DNS
- Monitors can be defined in plain English and are checked by AI
- Main data stays with a Belgian host holding ISO 27001
- Built API-first, which suits monitoring defined as code
- Belgian legal entity under EU law
Where Oh Dear falls short
- Cannot be self-hosted
- Scope stops short of a complete APM or infrastructure suite
- The bill follows the count of sites or servers
- Performance metrics pass through a second subprocessor
Standout feature. With Oh Dear, the monitor that watches availability also warns about a certificate nearing expiry or a link that has died.
Paris, France
A free tier covers 20 monitors at 5-minute checks; yearly billing lists Essentials at $24, Pro at $74 and Business at $249 a month; Enterprise is quoted individually
Demo on request
Best for: Product and support teams who would rather run checks, paging and customer-facing incident updates from one account
Hyperping SAS names itself in its terms as a French-law company with a Paris address, and the product runs from finding an outage to telling customers about it. Uptime, server, cron and SSL monitoring, logs and Playwright browser checks sit in the same account as alerting, on-call, incident management and the status page.
The free plan allows 20 monitors with 5-minute checks and one basic status page. Paid plans are quoted in US dollars: Essentials $24, Pro $74 and Business $249 a month with yearly billing, with 3, 10 and 20 seats included. Subscriber caps, extra seats and logs per GB all change the bill, and our review found no stated storage region, so ask for the processing terms.
What Hyperping does well
- The free tier includes 20 monitors plus a simple status page
- Monitoring, paging rotations and status pages share an account
- Playwright checks can walk through login and purchase flows
- Higher plans add private pages, SSO and your own domain
- The terms name a French company
Where Hyperping falls short
- Plans are priced in US dollars
- Lower plans cap the subscriber count
- Seats and logs billed per GB can inflate the invoice
- The reviewed pages give no storage region
Standout feature. Hyperping is the one product here that keeps escalation and on-call rotas next to the checks and the public status page.
St-Jean-de-Gonville, France
Founded 2012
Prepaid credit packs begin at €5; the vendor example of 10 websites checked every 2 minutes works out near €1.83 a month; 100,000 credits are free to test
Demo on request
Best for: Side projects and small agencies after inexpensive, high-frequency checks with a basic hosted status page
According to its about page, updown.io is the work of a single developer, and its legal name is the sole proprietorship of Adrien Rey-Jarthon, based in the French department of Ain. It dates from 2012 and has no subscription. Each credit buys one check, the smallest pack costs €5, and the pricing example is ten sites tested every two minutes for about €1.83 a month.
Checks can be set anywhere from 15 seconds to one hour, over web, TCP and ping protocols, and a heartbeat mode listens for cron jobs. Before an alert fires, two locations must agree the site is down. Sub-processors include OVH in France and Hetzner in Germany, with DigitalOcean in the US also listed. The status pages are reports without subscribers, and a one-person business has no support structure.
What updown.io does well
- Pay for checks as you use them, with no subscription
- Intervals can drop to 15 seconds
- A hosted status page comes with every account
- Every account is covered by a data processing agreement automatically
- The monitoring nodes are listed publicly
Where updown.io falls short
- A single person runs the business
- The status pages report figures but lack incident handling
- A few sub-processors are American
- Credit packs must be topped up from time to time
Standout feature. updown.io bills like a meter per check, offers 100,000 credits to try, and has no tier you can outgrow.
Tallinn, Estonia
Founded 2022
The Hobby tier costs nothing; Scale opens at €5 a month with usage on top, metered per monitoring event, SMS or voice alert and AI summary
Demo on request
Best for: Compact teams and agencies seeking checks, incident handling and a public status page at a low price
Lightkeeper OÜ of Tallinn develops Phare, which according to its website went online in September 2022 without outside funding. The checks reach websites, APIs, TCP ports, ping and SSL certificates from several regions. Incidents get a timeline, shared handling and a postmortem that AI summaries can pre-write, and a status page can be published on your domain, open or private.
Billing counts monitoring events, one per check run, with overage, SMS and voice alerts charged by the unit and a 10 percent allowance before monitoring pauses, according to the vendor's FAQ. Hobby costs nothing, and the Scale tier opens at €5 monthly. The site lists its suppliers by country: Germany for hosting, Slovenia for the CDN, the Netherlands for phone and France for email. Whoever writes in reaches the founder.
What Phare does well
- A free Hobby tier with no limit on members or projects
- Public or private status pages on your own domain
- Incidents get timelines and postmortems drafted by AI
- Hosting, CDN and email suppliers are in Europe
- Income and expenses are shown in public
Where Phare falls short
- Support comes from the founder, with no formal round-the-clock option on standard plans
- Billing per event makes the monthly total harder to predict
- Relatively young, online only since September 2022
- Single sign-on needs the Scale plan
Standout feature. No other vendor in this comparison shows its revenue and expenses on a public page the way Phare does.
Berlin, Germany
Founded 2018
Free tier / From €30/month
Demo on request
Best for: Engineering teams that watch APIs and websites and want checks kept in code
Checkly is a synthetic monitoring platform in Berlin, started in 2018 by Hannes Lenke and Tim Nolet, and its pitch is that a monitor is a piece of code. Browser checks are Playwright tests, API checks can chain requests with assertions and setup scripts, and a CLI keeps all of it in the repository so that the same checks can run in GitHub Actions, GitLab CI or Jenkins before a deploy.
The tool page reports a $20 million Series B in 2024 led by Balderton Capital, with Accel and CRV participating, plus a free entry level and paid plans beginning at €30 monthly. Checks run from 20+ data center locations, with Slack, PagerDuty, OpsGenie, email, SMS and webhook alerts and branded status pages. It does not cover infrastructure or APM, and teams without Playwright experience face a learning step.
What Checkly does well
- Playwright tests double as browser checks, so end-to-end work gets reused
- A CLI keeps monitors in the repository as code
- Running checks in CI/CD finds problems ahead of production
- API checks can chain several requests with assertions
- Berlin-based company with a free entry level
Where Checkly falls short
- Limited to synthetic checks, without infrastructure or APM
- Cost rises with how often and how many checks run
- Browser checks assume you know Playwright
- No open-source or self-hosted edition
Standout feature. With Checkly, one Playwright script can serve as both the CI test and the live production monitor.
Grays, England, United Kingdom
Founded 2012
Ten monitors come free; Superior costs €16.66 a month on annual billing (€19.99 paid monthly), Business €58.33 annually (€69.99 monthly), and Enterprise is by quotation
Demo on request
Best for: Small websites wanting Pingdom-like uptime, speed and certificate checks, starting on a free tier
StatusCake is run by TrafficCake Limited, registered in Grays, England, and has operated since 2012. The free plan includes ten uptime monitors tested every five minutes along with page speed, domain and SSL monitors. Superior from €16.66 a month billed annually gives 1-minute checks on 100 monitors, and Business from €58.33 gives 30-second checks on 300 monitors with server monitoring.
Jurisdiction is the catch. Britain relies on an adequacy decision and is not part of the EEA, and the processing agreement lets personal data be handled outside both areas, with AWS, Google Cloud and DigitalOcean named as infrastructure. It publishes no security certifications, cannot be installed on your own servers and stops at uptime and website checks. Paid plans come with a seven-day trial.
What StatusCake does well
- The free plan includes 10 working monitors
- Paid plans test as often as every 30 seconds
- Speed, domain and certificate monitors come bundled
- British company covered by an adequacy decision
- Paid plans start with a seven-day trial
Where StatusCake falls short
- Personal data can be processed beyond the UK and EEA
- Cannot be installed on your own infrastructure
- Covers less ground than a full observability platform
- Lists no security certifications
Standout feature. StatusCake gives ten monitors for free and prices its paid tiers in euro.
Romania
Founded 2010
The free level covers 1 page at 10-minute checks; Pro begins at $7 monthly for 5 monitors (the pricing page also shows $60 per year), with a 15-day trial
Demo on request
Best for: Small teams from the EU wanting alerts that escalate and a status page under their own brand
Per its terms, Monitive Com SRL is a Romanian private company from 2010 and operates the service. The design centres on escalation: first an email, then a text message at the three-minute mark and a call at ten minutes while the site is still down. Quiet hours, acknowledgement links and rules per monitor refine it, and Slack, Telegram, Pushover and PagerDuty receive alerts.
Checks cover HTTP/HTTPS with SSL verification, APIs, ping and TCP from 20+ locations on the home page and 23 in the FAQ. Branded status pages, SLA tracking and exportable reports require Pro, listed from $7 monthly for five monitors on one page and as $60 yearly on another. The free tier watches a single page every ten minutes. Neither a city nor a hosting location appears in what we reviewed.
What Monitive does well
- Alerts escalate from email through text to a phone call
- Quiet hours and rules set per monitor
- Status pages can group services together
- SLA tracking with reports in PDF or HTML
- Running since 2010
Where Monitive falls short
- Status pages require the Pro plan
- The free tier is tightly restricted
- Prices are in dollars
- The number of locations and the city differ between pages
Standout feature. On a fixed timer, Monitive pushes an unresolved outage from an email to a text message and then a call.
Slovakia
Yearly euro tiers: a €0 Free plan, then Solo from €108, Team at €360 and Scale from €660
Demo on request
Best for: Small sites and teams after a free or cheap monitor and an uncomplicated status page
The company behind UptimeRobot is UptimeRobot s.r.o.; its terms apply Slovak law and send disputes to a Bratislava court. A 2017 changelog line about Malta is outdated. The Free plan gives 5-minute checks and basic status pages, and paid plans reach 60, 30 and 15-second intervals.
Monitor types range from keyword and ping to UDP, cron and DNS, and a second data center in the region rechecks any failure before notifying you. Yearly euro prices run from €108 for Solo through €360 for Team to €660 for Scale. Certificate monitoring requires a paid plan, text and voice credits cost extra, and no hosting location is named in the pages we reviewed.
What UptimeRobot does well
- The free plan comes with simple status pages
- Check types include cron, UDP, keyword and DNS
- Yearly prices are shown in euro
- Paid plans allow subscribers and a custom domain
- A second regional data center confirms failures before an alert goes out
Where UptimeRobot falls short
- Certificate monitoring is a paid feature
- Status pages on the free plan are basic
- Text and voice credits are charged on top
- The hosting location is not named
Standout feature. UptimeRobot puts cron, UDP and DNS checks on the same yearly euro price list as ordinary website checks.
London (offices in Alphen aan den Rijn, Erkrath and Saint-Cyprien), United Kingdom
A 30-day trial unlocks Enterprise; the pricing page lists Core at $42 and Pro at $60 per month, 10% cheaper when paid yearly; Enterprise is custom
Demo on request
Best for: Operations and SRE staff who need scripted web and API checks run from many regions
Uptrends is a synthetic monitoring service that runs uptime, browser, transaction and API checks, and it now sits under ITRS Group Limited in London. Its contact page still lists offices in Alphen aan den Rijn, Erkrath and Saint-Cyprien. Browser checks run in Chrome and Edge, transactions cover logins and checkouts, and API calls can be chained with assertions.
Core starts from $42 a month and Pro from $60, with a 10 percent discount for annual billing, and a 30-day trial carries Enterprise access. Pro adds 1-minute checks and more than 230 multi-select checkpoints from US and EU regions, while Enterprise adds 30-second checks, monitoring inside your firewall, Terraform, OpenTelemetry, SSO and SCIM. The supplier named in the terms can be a group affiliate, and the storage location of results is not stated.
What Uptrends does well
- Browser, transaction and API checks sit next to ordinary uptime
- Checkpoints in US and EU regions, over 230 on Pro
- Pro has unlimited public status pages
- Enterprise brings Terraform and OpenTelemetry
- The 30-day trial grants full Enterprise access
Where Uptrends falls short
- Prices are in dollars and the billing basis is unclear
- A group company holds the contract and affiliates may be involved
- The pages read give no storage location
- Several key features need Pro or Enterprise
Standout feature. Uptrends pairs scripted browser checks with checkpoints in the US and EU and offers a real user monitoring add-on.
Riga, Latvia
Founded 2005
No licence cost as open source; support and services are sold separately
Demo on request
Best for: Teams that run their own servers and networks and want to watch it all without paying per host
Zabbix SIA in Riga has developed Zabbix since 2005 as GPL software. Data arrives via agents, SNMP, IPMI or checks without an agent, and proxies spread the load across sites. No licence fee applies at any size, so the cost is hardware, administration time and optional support.
In an uptime comparison it plays a different role from the hosted checkers: it explains the machine behind the page, not only whether the page answers. Its database is yours to run, the interface favours function over looks, and tracing and APM are weak spots. In return, telemetry about your estate stays on your network, which is a data-location answer no hosted vendor can give.
What Zabbix does well
- Open source and free, with no cap on hosts or metrics
- Has a track record at very large installations
- Gathers data via agents, without agents, SNMP and IPMI
- Proxies serve remote or segmented sites
- Latvian company in the EU with paid support on offer
Where Zabbix falls short
- Installing and tuning takes genuine effort
- The interface is practical rather than attractive
- Tracing and APM are weak areas
- The database underneath is yours to maintain
Standout feature. Nothing in Zabbix is metered, whether checks, hosts or metrics, which sets it apart on this list.
Nuremberg, Germany
Annual billing by sensor tier: $200 monthly for 500 sensors, $358 for 1000, $742 for 2500, $1,300 for 5000 and $1,642 for 10000; delivered as PRTG Hosted Monitor, or as on-prem Enterprise Monitor for bigger setups
Demo on request
Best for: IT and network teams that want a single sensor-driven console covering servers, networks, cloud and OT
Paessler GmbH of Nuremberg sells PRTG, a console where sensors watch servers, networks, cloud services and operational technology. Licensing counts sensors: PRTG 500 from $200 a month, PRTG 1000 from $358, PRTG 2500 from $742, PRTG 5000 from $1,300 and PRTG 10000 from $1,642, billed annually. Larger estates move to the on-prem Enterprise Monitor.
You can install it yourself or take the managed PRTG Hosted Monitor, and the trial runs 30 days with every feature and no card. The tool is not open source, sensor pricing can grow with a large estate, and its discovery is more manual than Checkmk's. It is an infrastructure monitor rather than an outside-in website checker, so it complements a service such as Oh Dear or Uptrends.
What Paessler PRTG does well
- A single console spans servers, networks, cloud and OT
- The full product can be tried for 30 days without a card
- Choose a local install or PRTG Hosted Monitor
- A long-established sensor library handles typical infrastructure
- German vendor under EU jurisdiction
Where Paessler PRTG falls short
- Closed source
- Sensor-based licensing gets costly in large estates
- A German product that is priced in US dollars
- Discovery is less automatic than in Checkmk
Standout feature. Paessler PRTG lets a network team try the whole product with real sensors for 30 days before buying a licence.
