HetrixTools

Overview

HetrixTools is a monitoring service for uptime, servers, domains, certificates and blacklist status, with alerts that can feed into a wide range of team tools. It is a strong fit for operators who want frequent checks across several parts of their infrastructure without assembling separate services. The key trade-off is that the free plan’s capacity and location coverage are modest, and ongoing use requires account activity every 90 days.

Key features

All listed plans check at one-minute intervals, while monitoring locations increase from four on Free to 12 on Enterprise. More locations make paid tiers a better fit for services whose availability may vary by region; the free allowance is less suited to broad geographic monitoring. Uptime monitoring is available from up to 12 global locations.

Coverage extends beyond uptime to server metrics, domain expiration, SSL certificates, nameserver changes and major blacklists, including Microsoft SNDS. SSL-expiry alerts and keyword monitoring add useful checks for site operators, while those who need only a basic uptime signal may be paying for breadth they do not use. Server agents support Linux, Windows, macOS and shared hosting environments.

Private and public reports and public status pages support both internal tracking and customer communication. White-labeling ranges from partial to full, with white-label domains on paid plans. Paid plans also add sub-accounts, API access and activity logs; the listed sub-account quantities are 1, 5 and 20, and log retention ranges from 15 to 90 days across plans.

Alerts cover email, phone calls, SMS, Telegram, Pushbullet, Pushover, ntfy.sh, Slack, Discord, Mattermost, Rocket.Chat, Microsoft Teams, Google Chat, PagerDuty, Jira, Opsgenie, ilert, VictorOps, Zenduty, SIGNL4 and webhooks. This selection can fit into existing escalation workflows, but phone and SMS usage is capped by monthly credits. Extra credits cost $0.1 each.

Pricing

The free plan costs nothing and includes 15 uptime monitors, 15 server monitors, one-minute checks and four locations. It is free for life, but the account needs activity every 90 days. The homepage also advertises 32 free blacklist monitors. This is a useful entry point for a small setup, though the check count and locations limit its reach.

Professional costs $9.95 a month, billed monthly, for 30 uptime monitors, 30 server monitors, one-minute checks, six locations and 25 phone/SMS credits per month. It is the natural step up for a small operation that has outgrown Free, but adds only two locations and remains limited in credits.

Business costs $19.95 a month, billed monthly, and doubles the monitor counts to 60 each, raises location coverage to nine and includes 50 phone/SMS credits monthly. It suits teams that need more monitoring capacity without Enterprise’s 200-monitor allowance.

Enterprise costs $49.95 a month, billed monthly, and includes 200 uptime monitors, 200 server monitors, one-minute checks, 12 locations and 125 phone/SMS credits per month. It is aimed at larger deployments; high-volume customers can contact Sales for custom pricing. Yearly billing offers two months free. Support is Normal on Free and Premium on paid plans.

Platforms

The listed platforms are Linux, macOS and Windows. The server monitoring agent also supports shared hosting environments, making the monitoring useful beyond conventional server installations.

Who it's for

HetrixTools suits website and infrastructure operators who want uptime, server, domain, certificate and blacklist monitoring in one service, especially when one-minute checks and varied alert destinations matter. Its paid plans are more appropriate for teams needing more locations, monitor capacity, sub-accounts or white-label domains. It is less compelling for a small project that needs only a handful of simple availability checks.

Pros and cons

• Pros: One-minute checks run across every plan, including Free, so lower-cost users do not give up check frequency.
• Pros: Coverage spans uptime, server metrics, domains, SSL, nameserver changes and blacklists, reducing the need for separate monitoring categories.
• Pros: A broad set of alert channels can connect monitoring to common chat and incident-management workflows.
• Cons: Free is limited to 15 uptime and 15 server monitors and four locations, with account activity required every 90 days.
• Cons: Phone/SMS credits are capped by plan, and additional credits cost $0.1 each.
• Cons: White-label domains and sub-accounts are paid-plan features, so teams needing customer-facing branding or separated access cannot stay on Free.

Alternatives

UptimeRobot is worth considering for hobby and nonprofit projects: its free plan offers 50 monitors at five-minute intervals, trading away HetrixTools’ one-minute cadence for a larger free monitor count.

Dotcom-Monitor is another free option, with up to 25 targets, five-minute monitoring, two locations and email alerts; choose it if those limits match the need for a simpler free setup.

Checkmate may suit users who prefer a self-hosted service: its free plan includes all features, unlimited monitors and 12 alert channels.

openstatus offers a free Hobby plan with one monitor, one status page, three components and 10-minute minimum checks, making it an option for a smaller, slower-checking setup.

SolidPing offers a free plan with 100 monitors, five team members, 10 check executions per minute and one private-location agent.

Spectate offers a Hobby plan with five monitors or servers and one status page, or a Solo plan at $12 a month, billed $144 billed yearly, for one user and 15 monitors/servers with one-minute checks.

Better Uptime has a free personal-project plan with 10 monitors and heartbeats, one status page and Slack and email alerts; it is an alternative for users whose needs fit that smaller package.

Uptimia offers a Basic plan at $9 a month, billed annually, with 10 uptime checks, one-minute testing, one advanced check, one server and one status page.

Verdict

Choose HetrixTools if you need one-minute checks across uptime and related infrastructure monitoring, plus alert routes that can fit an existing team workflow. Its strongest case is breadth combined with frequent checks; look elsewhere if a larger free monitor allowance or a narrower, simpler uptime tool matters more than that combination.
