Comparing paid plans as well? See the best website monitoring tools compared.
Updated 15 October 2026. Competitor free plans in this guide were last checked against each vendor's own pricing page on 30 September 2026.
Why Free Monitoring Matters
Not every website needs a $50/month monitoring plan. Personal blogs, side projects, small business sites, and early-stage startups all need monitoring, but their budgets don't always have room for paid tools.
Several genuinely free monitoring tools exist in 2026, but every free plan has limits, and the wrong one means missed issues or a quick upgrade.
This guide compares the best free options available right now, with honest assessments of what each does well and where they fall short.
The Tools
1. UptimeRobot (50 Free Monitors)
What you get for free:
- 50 monitors
- 5-minute check intervals
- Website (HTTP), keyword, ping and port monitoring
- Email alerts, the mobile app, and 5 integrations (Google Chat, Discord, Pushover, Pushbullet and Splunk)
- 1 status page on an UptimeRobot address
- 3 months of data retention
- No credit card required
Strengths: UptimeRobot's 50-monitor free plan is hard to beat for quantity. If you need basic uptime checks for many sites, it's an obvious choice. Setup is fast, and the service has been around for years.
Keyword monitoring on the free plan is a nice touch: you can check that a specific word appears on the page, which catches some content errors that a basic uptime check misses. UptimeRobot's terms also allow commercial use on every plan, including Free.
Limitations:
- No SSL certificate or domain expiry monitoring on the free plan
- No DNS monitoring
- No multi-location checks or slow-response alerts
- No visual monitoring
- Slack, Telegram and Microsoft Teams alerts need a paid plan, and SMS or voice calls need purchased credits
- Monthly email reports stop after the first 3 months
Best for: Monitoring many sites with basic uptime checks. See our detailed UptimeRobot comparison for more.
2. StatusCake (free plan under an A/B test)
What you get for free: StatusCake's free plan is under an A/B test. The US pricing page currently shows 3 uptime monitors checked every 15 minutes, and leaves the free page-speed, SSL and domain cells blank. Its free-plan page still says 10 monitors at 5 minutes, with 1 page speed, 1 SSL and 1 domain monitor. Check statuscake.com/pricing before you rely on a number.
Strengths: The free-plan page still describes uptime, page speed, SSL and domain checks, and it still says the free plan will stay free for life. The US pricing page does not currently show those page-speed, SSL and domain cells, so confirm which page you are seeing.
Limitations:
- The published free monitor count and interval disagree between the US pricing page and the free-plan page
- No visual monitoring
- Status pages are a separate paid product (StatusCake Pages)
Best for: A site you can re-check against the current pricing page before you depend on a free limit.
3. HetrixTools (15 Free Monitors)
What you get for free:
- 15 uptime monitors (plus 15 server monitors)
- 1-minute check intervals
- Website, ping, port and SMTP (mail server) monitoring
- Checks from 4 locations you choose, out of 12
- Email, Slack, Discord, Telegram, Microsoft Teams, webhooks and more
- SSL validity and expiry monitoring, domain expiry monitoring and nameserver change alerts
- Public status pages and unlimited uptime report history
- A separate free Blacklist Monitor with 32 monitors
Strengths: HetrixTools is remarkably feature-rich for a free tool. The 1-minute check interval is the fastest on this list, and the notification options are generous: Slack, Discord, Telegram and Teams are all on the free plan.
The separate Blacklist Monitor checks whether your IP addresses or domains appear on email blacklists, which is valuable if your site sends transactional email.
Limitations:
- You must log in at least once every 90 days to keep the free account active. This is the biggest catch. If you set it up and forget about it, you risk losing your monitoring.
- SMS and phone call alerts are pay-per-use on the free plan (no credits included)
- No visual monitoring or page speed testing
- Free includes Normal support; paid plans include Premium support.
Best for: Power users who want fast checks and many notification channels, as long as they remember to log in every quarter.
4. Better Stack (Uptime) (10 Free Monitors)
What you get for free:
- 10 monitors, plus 10 heartbeats (checks for scheduled jobs)
- 3-minute check intervals
- Email and Slack alerts
- 1 status page
Strengths: Better Stack offers a polished experience with clean dashboards and well-designed status pages. The free status page is useful: if your site goes down, visitors can check it for updates.
The 3-minute check interval is faster than the 5-minute interval on the UptimeRobot free plan. Better Stack's log and incident management tools are there if you upgrade later.
Limitations:
- Only 10 monitors
- SSL certificate expiry alerts need a paid plan
- Phone call and SMS alerts are on paid plans
- No visual monitoring
- The free tier is labelled "Free for personal projects"
Best for: Teams that value good design and want a free status page alongside their monitoring.
Where Visual Sentinel fits (no free plan)
What new users get:
- A first check of your site with no card
- Then a 7-day trial (card required) or a subscription, from $15/month
- No ongoing free monitors, and nothing that stays free forever
Solo, the entry paid plan ($15/month, or $153/year):
- 10 monitors
- Uptime checks every 5 minutes
- Visual monitoring on 1 site, every 30 minutes
- SSL certificate checks, with reminders 13, 3, and 1 days before expiry (20 and 6 days are optional)
- Checks from Europe and the US
- A single expected-text setting on every plan. Keyword rules (must contain or must not contain) start on Starter
- Email, Slack, Discord, Microsoft Teams, Telegram, PagerDuty, Opsgenie, webhooks, WhatsApp, Prometheus, and push notifications in the mobile app
- No SMS and no phone-call alerts
Strengths: The first check needs no card, so you can see the site's result before you subscribe. Solo then covers uptime and SSL from Europe and the US, plus visual monitoring on 1 site.
Limitations:
- The 7-day trial requires a card, and the card is charged on day 8 unless you cancel before the trial ends
- Checks every minute start on Business ($80/month), not on Solo
- Visual pages on Solo are 1 site, every 30 minutes. Starter covers 5, every 15 minutes
What that means in practice: A 5-minute interval means a short outage can start and end between two checks, which is the same trade-off as on the free UptimeRobot plan. For a forever-free ping, UptimeRobot (50 monitors) or HetrixTools (1-minute checks) are better fits. If you want uptime, SSL, DNS and a screenshot check in one place, Solo covers them for $15 a month.
Best for: A few important sites, once you are ready to subscribe or start the 7-day trial.

Which Tool Should You Choose?
If you need to monitor many sites with basic checks:
UptimeRobot. 50 monitors is the most generous free tier by far. If you just need to know when a site goes down, this covers it.
If you want uptime and SSL covered on a few key sites:
Visual Sentinel is a paid option here: there is no free plan, but you can see a first check with no card, then start a 7-day trial (card required). See Where Visual Sentinel fits and our full feature comparison.
If you need the fastest check interval:
HetrixTools. 1-minute checks on the free plan, from 4 locations you choose. Just set a calendar reminder to log in every 90 days.
If you need a free status page:
Most tools here include one. HetrixTools includes public status pages on every plan, and UptimeRobot and Better Stack each include 1. StatusCake sells status pages as a separate product.
If you need basic uptime plus performance data:
StatusCake, if the page you see still includes a free page-speed check. The free-plan page says that check runs once a day. The US pricing page currently leaves that cell blank, so confirm it before you rely on it.
The Combination Approach
You can also pair two tools:
- UptimeRobot (50 monitors) for broad uptime coverage across all your sites
- A paid SSL check (Visual Sentinel Solo is $15/month) on your most important sites, since UptimeRobot's free plan doesn't include SSL monitoring
This combination is not free end to end: UptimeRobot covers uptime at no cost, while the SSL check on Solo is $15 a month.
When to Upgrade to Paid
Free monitoring is a great start, but you'll eventually hit limits. Consider upgrading when:
- You need more monitors than the free tier allows
- You need faster check intervals (Visual Sentinel's fastest is every minute, on Business and Agency. Some other tools advertise 30-second checks.)
- You want visual monitoring, to catch pages that load but look broken
- You need advanced notifications (PagerDuty, custom webhooks, on-call rotation)
- You need longer data retention for compliance or reporting
- You need API access for integration with your own tools
- You need multi-user access with role-based permissions
All of the tools listed here have paid plans. Visual Sentinel's paid plans start with Solo at $15 a month, and checks every minute start on the Business plan ($80/month). See our pricing, and our comparison pages for the differences in detail.
Conclusion
You can monitor a site in 2026 without spending anything if you accept a free plan's limits. Pick the plan whose limits you can live with, or pair a free uptime tool with a paid one for broader coverage. A paid tool such as Visual Sentinel makes sense once you need SSL, DNS or visual checks.
Start with any tool on this list, or add your site and see its first check with no card, then start a 7-day trial or subscribe from the pricing page. The worst monitoring setup is no monitoring setup.

Start 7-day trialCommon questions
What is the best free website monitoring tool in 2026?
It depends on what you need. UptimeRobot gives the most monitors (50, checked every 5 minutes). HetrixTools checks most often (every minute, from 4 locations), but you must log in every 90 days. Visual Sentinel has no free plan. You can run a first check with no card, then start a 7-day trial (card required) or subscribe from $15/month. Better Stack gives 10 monitors. StatusCake's free count is under an A/B test: the US pricing page shows 3, and the free-plan page still says 10.
Can I monitor my website for free forever?
Yes, with some tools. UptimeRobot, StatusCake, HetrixTools and Better Stack have a free plan, not just a free trial. HetrixTools is the one with a condition: you must log in at least once every 90 days to keep the free account active. Free plans limit things like monitor count, check frequency, alert channels and history, so compare those limits with what you need.
How many websites can I monitor for free?
UptimeRobot: 50. HetrixTools: 15. StatusCake: see its pricing page. The US page currently shows 3 uptime monitors; its free-plan page still says 10. Better Stack: 10 monitors plus 10 heartbeats. Visual Sentinel: none on an ongoing free plan. The number of monitors doesn't tell the whole story, so also check how often each tool checks, which alerts are included and whether SSL checks are part of the free plan.
Is UptimeRobot still good in 2026?
Yes, for basic uptime checks across many sites. Its free plan gives 50 monitors checked every 5 minutes, keyword checks, 1 status page and 3 months of history. SSL and domain expiry, DNS and multi-location monitoring are on its paid plans, so pair it with a tool that checks SSL if an expired certificate is a risk for you.
What should I look for in a free monitoring tool?
Check the number of monitors, the check interval (how often it tests your site), what it checks (uptime, SSL, DNS, visual), which alert channels are included (email, Slack, and so on), where checks run from, how long history is kept, and any conditions such as having to log in regularly.
