UptimeRobot

UptimeRobot is a service-monitoring platform for websites, APIs, servers and other endpoints. It is best suited to site owners, freelancers and operations teams that need many monitor types and notification routes in one account. Its broad coverage is compelling, but faster checks, more monitors and collaboration are reserved for paid plans.

Overview

UptimeRobot monitors HTTP, ports, ping, keywords, APIs, UDP, DNS, SSL and domains, with server monitoring also supported. SSL-expiry alerts and keyword monitoring cover practical failure modes beyond simple reachability. Branded real-time status pages can publish incidents and maintenance updates, making the service useful for communicating outages as well as detecting them.

Alert delivery is unusually broad: email, SMS, voice call, email-to-SMS, mobile push, Slack, Microsoft Teams, Telegram, Discord, Google Chat, Mattermost, PagerDuty, Splunk On-Call, Pushbullet, Pushover, Zapier and webhooks are supported. UptimeRobot integrates with more than 20 services, although the free plan permits only five integrations. Role-based access supports permission control for teams. UptimeRobot says it is SOC 2 and GDPR compliant, and Stripe handles card payments under PCI Service Provider Level 1 certification.

Key features

• Monitor variety: The combination of web, network, API, DNS, SSL, domain and server checks suits mixed environments better than a single-purpose uptime checker.
• Intervals by plan: Free monitoring runs every five minutes; paid plans can check every minute, with Team reaching 30 seconds and Scale 15 seconds. Faster intervals matter when short outages or rapid incident response are costly.
• Status communication: Branded status pages provide a customer-facing place for live incidents and maintenance. The number of pages and custom-domain options depend on the plan.
• Mobile access: Android and iOS apps add mobile push alerts and access away from a desktop.
• Operational routing: Webhooks, Zapier and PagerDuty appear on Team, while the wider channel list can connect alerts to both lightweight and on-call workflows.

Pricing

UptimeRobot uses a freemium model. The Free plan costs nothing, requires no card and is aimed at hobby and non-profit projects. It includes 50 monitors, five-minute checks, the listed HTTP, port, ping, keyword, API, UDP, DNS, SSL and domain monitor types, and basic status pages. Its 50-monitor allowance is generous for a no-cost tier, but the slower interval and five-integration cap make it less suitable for production alerting.

Solo costs $9 a month when billed annually and targets freelancers and small sites. It provides 10 monitors, 60-second checks, all monitor types plus SSL and DNS, three status pages and your own domain. This is the practical entry point for faster detection, although its 10-monitor tier is far smaller than Free's monitor allowance. The general paid starting price is $12 per month on annual billing, and annual payment saves about 15%, so readers should confirm which paid tier and billing presentation apply to their account.

Team costs $35 a month, billed annually, for small production teams. It raises capacity to 100 monitors, checks every 30 seconds, includes three seats and adds webhook, Zapier and PagerDuty support. Scale costs $65 a month annually for high-volume self-service monitoring: 200 or 500 monitors, 15-second checks, five seats and unlimited status pages. Enterprise uses custom pricing and can provide custom intervals, SSO, audit logs, SLA and security-review options, plus custom invoicing. SMS credits are a separate $3.00 one-time purchase for 10 credits. New subscriptions and upgrades have a 14-day money-back guarantee; PayPal is unavailable for new subscriptions, while major cards and wire transfers are accepted.

Platforms

Mobile apps are available for Android and iOS. The service is primarily account-based, so teams can receive alerts and manage monitoring through supported web workflows and the mobile apps.

Who it's for

Choose UptimeRobot if you need one service to watch websites, APIs and infrastructure while sending alerts into several communication or on-call systems. Free is a strong fit for personal, hobby and non-profit monitoring where five-minute detection is acceptable. Solo suits a freelancer or small site that needs minute-level checks and a custom-domain status page. Team and Scale fit production operations that need shorter intervals, more monitors, seats and incident integrations. Enterprise is for organizations requiring procurement, compliance and identity controls. It is less attractive when you need more than five free integrations, very fast checks without a paid subscription, or a free tier with only a small number of monitored endpoints.

Pros and cons

• Pro: Nine monitor categories plus server, SSL and keyword monitoring cover diverse technical checks.
• Pro: Extensive alert channels, including webhooks and on-call services, fit established incident workflows.
• Pro: Free includes 50 monitors and no card requirement, lowering the barrier for small projects.
• Con: Free checks run only every five minutes and allow five integrations, limiting rapid response and workflow breadth.
• Con: Solo drops to a 10-monitor tier, so faster checks can require accepting less monitor capacity than Free.
• Con: Seats, shorter intervals and unlimited status pages appear only on higher-priced plans.

Alternatives

For API-focused monitoring, Site24x7 API Monitoring offers a free plan for up to 50 resources with instant downtime email alerts and apps across Android, iOS, Linux, macOS, web and Windows. APIContext is a better fit for API, MCP and HTTP testing with 10,000 tests per month on its free tier, but it excludes simulated browser journeys.

Dotcom-Monitor provides up to 25 targets, five-minute checks, two monitoring locations and email alerts on its free plan. Postman is the alternative when API client work, specifications, mock servers and collection running matter more than continuous uptime monitoring.

Tallwatch offers 10 monitors, 60-second checks from three regions, three team members, one custom-domain status page and email and Slack alerts for free. Watchlog suits users who need an agent, API check, custom events and log storage alongside basic monitoring. Checkly targets uptime plus browser and API checks, with 10 uptime monitors, 1,000 browser runs, 10,000 API runs and six locations in its Hobby plan. HostTracker is a simpler option with two free monitors and 30-minute checks.

Verdict

UptimeRobot is a strong choice for anyone wanting broad endpoint coverage, many alert destinations and a clear path from free monitoring to team operations. Choose it when monitor variety and integrations matter more than a generous free check interval. Look elsewhere if five-minute free checks and five integrations are too restrictive, or if your priority is specialist API testing or browser-based journeys.
