10 Best Uptime Monitoring Tools of 2026

Better Stack ranks first because it covers the whole outage path, from detection to waking someone up to telling customers, without a second tool. The free plan includes 10 monitors and heartbeats, a status page and Slack and email alerts, which is enough for a personal project. For a team, the key purchase is the Responder license at $29 per month billed yearly or $34 monthly, which adds on-call scheduling, incident management and unlimited phone and SMS alerts. Uptime checks run as often as every 30 seconds from several locations and cover HTTP keywords, TCP and UDP ports, ping, DNS, SSL and domain expiry, with screenshots of errors and multi-step incident verification to cut false alarms. Playwright transaction checks cost $1 per 100 minutes. The trade-off is that extra monitors are sold in blocks of 50 and status page options such as white-labeling are separate line items, so read the pricing table closely.

UptimeRobot is the easiest way to watch a lot of endpoints without spending anything. The free plan covers 50 monitors at 5-minute intervals, allows commercial projects and needs no credit card, and it already includes keyword, port, ping, UDP, DNS and API checks plus basic status pages. Paid tiers are sold as Solo, Team and Scale. Solo moves checks to every 60 seconds and adds SSL and DNS monitoring, three status pages on your own domain and 12 months of data retention. Team cuts the interval to 30 seconds, adds three login seats, white-label status pages and Webhook, Zapier and PagerDuty integrations, and Scale reaches 15-second checks. It also monitors third-party services you rely on and offers a mobile app, API, CLI and MCP server. It ranks below Better Stack because on-call scheduling is lighter and SMS or voice alerts are bought as credits. The pricing page here showed euros, so the USD price is pending.

Checkly is the strongest pick for developers who want monitoring to behave like tests. Checks are written in code, run on a schedule and deployed from the terminal with the Checkly CLI, or managed through Terraform and Pulumi providers, so they go through code review like everything else. Uptime monitors cover HTTPS, TCP, DNS, ICMP, SSL, gRPC, traceroute and heartbeats, and synthetic monitoring runs browser checks and full Playwright Check Suites. The free Hobby plan includes 10 uptime monitors at 2-minute frequency, 1,000 browser runs and 10,000 API runs a month. Starter at $24 per month billed annually raises that to 50 monitors at 1-minute frequency with SMS alerts, and Team at $64 adds 30-second checks, 21 locations, private locations and every alert channel. The catch is metering: runs beyond your plan are billed as overages, so a busy schedule of browser checks needs a budget.

Hyperping packages the things a small team needs during an outage into flat plans. The free plan gives one person 20 monitors at 5-minute checks, a server monitoring agent and a basic status page. Essentials at $24 per month billed yearly, or $290 a year, includes three seats, 50 monitors, five server agents, three browser checks, 5 GB of logs, a status page on your own domain with 100 subscribers, on-call and escalation policies, phone call alerts and every integration. Pro at $74 adds 250 monitors, ten seats, private and multilingual status pages and SAML SSO. Each paid plan also includes a limited allowance of its Ask Hyperping AI assistant, or unlimited use with your own model key. Compared with Better Stack it is simpler and more predictable, but it offers fewer browser checks per plan and lacks the wider log and error tracking suite. Extra seats cost $7 to $12 per month.

Cronitor started with cron jobs and still does them better than most uptime tools, but every plan also includes website, API and heartbeat monitoring. The free Hacker plan gives 5 monitors with email and Slack alerts, a basic status page and 5-minute checks, which suits a homelab or side project. Business has no base fee: you pay $2 per monitor and $5 per user each month after a 14-day trial, so 20 monitors and three users come to $55 a month by Cronitor's own example. That unlocks 30-second checks, SMS alerts, PagerDuty, OpsGenie and other on-call integrations, 12 months of data retention and SAML SSO for an extra $5 per user. Browser checks cost $1 per 1,000 runs and real user monitoring is sold by event volume. The per-monitor model is the cheapest way in for small setups, but it gets expensive compared with tiered plans once you pass a few dozen monitors.

StatusCake is a straightforward website monitor that bundles uptime with the checks agencies usually bolt on separately. The free plan includes 10 uptime monitors at 5-minute intervals plus one page speed, domain and SSL monitor. Superior, at $20.41 per month billed annually or $24.49 monthly, raises that to 100 uptime monitors at 1-minute intervals, 15 page speed monitors, 50 domain and 50 SSL monitors, three server monitors, reporting and 75 SMS credits a month. Business at $66.66 per month billed annually adds 30-second tests, 300 monitors, white-label reports, an audit log and up to nine team members. SSL monitoring flags expiring certificates and mixed content, and domain monitoring watches expiry dates and blacklists. It lacks on-call schedules and browser checks, so teams with complex apps will outgrow it, and Superior allows only one team member. For a portfolio of marketing sites it covers a lot for the price.

Site24x7 is the monitoring suite from Zoho, and its website packs are among the cheapest ways to check many sites every minute. Web Uptime costs $9 per month paid annually or $10 monthly and includes 25 websites, transaction monitors, a 1-minute polling interval, three status pages, multiple users, third-party integrations and email support. Web Perf at $36 per month paid annually raises that to 40 websites, eight transaction monitors, eight monitoring locations and 100,000 real user monitoring page views. The bigger reason to choose it is the upgrade path: the same account can add server, cloud, Kubernetes, network and application monitoring, so a growing IT team does not have to migrate. The drawbacks are that the entry pack checks from a single location, which makes false alarms harder to rule out, and the many packs and add-ons make the pricing harder to read than flat plans. There is a 30-day free trial but no permanent free plan.

Datadog Synthetic Monitoring has the broadest testing scope here, but it is built for teams already inside Datadog. API tests cost $5 per 10,000 runs a month billed annually, or $7.20 on demand, and browser tests $12 per 1,000 runs. Tests can run every minute for API and browser checks and every 30 seconds for network paths, from Datadog-managed locations across AWS, GCP and Azure or from private locations inside your network. Browser tests can be recorded without code, and Datadog says they recompute broken locators automatically after small frontend changes. Mobile app tests and CI/CD integration let the same tests guard deployments. The real advantage is correlation: a failed check links straight to the metrics, traces and logs that explain it. For a small team that only needs to know when a site is down, per-run billing is harder to forecast than a flat plan, and the platform takes longer to learn than a dedicated uptime tool.

Uptime.com offers one of the widest menus of check types in this group. Basic checks cover HTTP(S), SSL certificates, DNS, ping, TCP, UDP, SSH, SMTP, IMAP, POP, FTPS, NTP, WHOIS, blacklists and malware, and advanced checks add API, transaction, page speed, webhook and heartbeat monitoring. Checks run every minute from more than 100 probe servers, with IPv4 and IPv6 test locations and private locations behind a firewall. Website Monitoring starts at $9 per month billed yearly, or $108 a year at the smallest quantity, and includes uptime, transaction and API monitoring, email and SMS alerts, phone alerts, escalations, maintenance windows, customizable reporting and unlimited users. New users get a 30-day money-back guarantee. It ranks lower because there is no permanent free plan, the price scales with a quantity slider, so the true cost needs a calculator, and it lacks the on-call scheduling and status page bundles of the tools above it.

Pingdom, owned by SolarWinds, is one of the oldest names in uptime monitoring, and its product is still easy to set up. Synthetic monitoring covers uptime, multi-step transactions and page speed from more than 100 test servers, and you can pick regions such as North America, Europe, Asia and Australia. Before alerting, Pingdom runs a second check to filter out false positives, then notifies by email, SMS, push or webhook, with delays of up to an hour and up to four repeat alerts. For each incident it offers root cause analysis with traceroute and server response codes, and public status pages are included in all plans. Real user monitoring is sold separately by page views with 13 months of retention. The smallest synthetic tier includes 10 uptime checks, one advanced check and 50 SMS, which is thin next to rivals' free plans, and there is no on-call scheduling. Prices load with JavaScript, so the USD figure is pending.
