Overview

HostTracker checks websites, servers and APIs from outside a customer’s network, with a monitoring network and integrations that reach beyond basic uptime checks. It is a strong fit for web agencies and hosting resellers overseeing multiple domains; teams with only a couple of low-risk sites may find its broader toolkit unnecessary.

The main trade-off is between broad coverage and tight entry-level limits: the free plan checks two monitors every 30 minutes, while the 30-day trial reaches 100 monitors with one-minute checks.

Key features

Fourteen monitor types span HTTPS uptime, ping, TCP ports, APIs, browser transactions, page speed, database queries and SNMP, plus domain and SSL expiry and Google Web Risk checks. That range can serve teams that want operational, performance and security signals in one service. A team that only needs a basic availability ping may be paying for breadth it does not use.

Checks run across more than 300 worldwide checkpoints on around 460 distributed agent machines. HostTracker rechecks failures from other locations, and users can choose how many confirmations are needed before declaring a monitor down. That helps limit false alarms; setting a high threshold, however, may delay notification when a real outage needs a fast response.

Fifteen alert channels include email, SMS, voice calls, webhooks, Slack, Microsoft Teams, PagerDuty, Telegram, Discord and web push. Public status pages are included in every plan, with incident and maintenance updates, email subscribers and an embeddable uptime badge. That makes customer-facing incident communication accessible even to small deployments.

Developer tooling includes a REST API with 182 operations, SDKs for JavaScript, Python, .NET and Go, a command-line tool, Terraform provider and MCP server. This is a meaningful advantage for teams integrating monitoring into existing workflows, though the trial applies fair-use limits to SMS and API access.

Security monitors cover SSL expiry and trust-chain issues, domain expiry, DNS blacklist listings, and malware or phishing flags through Google Web Risk. HostTracker has monitored websites since 2004, and its team owns customer support.

Pricing

The permanent free plan costs 0.00 USD per month (billed $0/month) and allows two monitors, two contacts and checks every 30 minutes. It suits a small personal setup or a limited evaluation, but the monitor cap and slow cadence make it a poor fit for active production coverage.

The 30-day free trial costs 0.00 USD per free (billed $0/month) and includes up to 100 monitors, 10 contacts and one-minute checks, with no credit card required. Fair-use limits apply to SMS and API access. It gives teams a much more representative view of the service than the permanent free plan, but it is time-limited.

Personal costs 5.00 USD per month (billed $5/month) for five monitors, five contacts and 10-minute checks. It is the lowest-cost paid option, appropriate for a small site portfolio where frequent checks are not essential. Solo costs 9.00 USD per month (billed $9/month) and raises the allowance to 10 contacts with one-minute checks, but includes only one monitor, so its faster cadence comes at the expense of coverage breadth.

Enterprise500 costs 149.00 USD per month (billed $149/month) for 500 monitors, 500 contacts and one-minute checks. Enterprise1000 costs 249.00 USD per month (billed $249/month) for 1,000 monitors, 1,000 contacts and 30-second checks. These are the listed options for broad, fast monitoring at scale; teams should match the monitor allowance to their domain count rather than assume the higher tier is automatically better.

Platforms

HostTracker is available on the web and through an API. Its developer tools support integration into workflows, but the platform list does not include mobile apps.

Who it's for

HostTracker is aimed at web agencies, hosting resellers and webmasters responsible for multiple domains. Its many monitor types, broad alert selection, status pages and infrastructure-oriented integrations make it especially relevant to teams managing varied customer environments. A single-site owner who needs only occasional uptime checks is better served by a simpler, less constrained entry plan.

Pros and cons

Pros: Broad monitoring coverage combines uptime, performance and security checks, useful for teams consolidating different operational checks.
Pros: Rechecks across worldwide checkpoints and configurable failure confirmations help reduce false alarms.
Pros: Every plan includes public status pages, and the API, SDKs, CLI, Terraform provider and MCP server offer several integration paths.
Cons: The permanent free plan’s two monitors and 30-minute checks are too limited for most production needs.
Cons: The low-cost paid plans trade off either coverage or check speed: Personal has five monitors and 10-minute checks, while Solo has just one monitor.
Cons: SMS and API access on the 30-day trial are subject to fair-use limits.

Alternatives

Website Monitoring Software, API Monitoring Tools and Synthetic Monitoring are useful starting points for comparing tools by monitoring focus.

Choose Better Stack if its free personal-project plan’s 10 monitors, one status page, exception allowance, session replays and retained logs better match your needs.

Cronitor is an alternative with a free Hacker plan for five monitors, email and Slack alerts, one status page and five-minute fastest checks.

Consider Tallwatch for its free plan’s 10 monitors, 60-second checks from three regions, up to three team members and custom-domain status page.

UptimePad offers a free plan with 10 monitors, five-minute checks, one region, SSL and DNS checks, one status page, 30 days of history and one seat; it may fit teams prioritizing those free-plan allowances over HostTracker’s broader monitor types.

Yottaa Real User Monitoring is another option, with free diagnostics and no credit card required.

WebSitePulse offers paid HTTP performance monitoring from 9.00 USD per month at a 10-minute interval and one monitoring location, as well as a performance transaction plan at 15.00 USD per month.

UptimeRobot has a free plan for hobby and nonprofit projects with 50 monitors and five-minute monitoring intervals, making it worth considering when monitor count matters more than faster checks.

Uptimia may suit small websites looking for a Basic plan with 10 uptime checks, one-minute testing, one advanced check, one server and one status page; it costs 9.00 USD per month billed annually.

Verdict

HostTracker is best for agencies, resellers and webmasters who need external monitoring across multiple domains, with varied checks, numerous alert routes and developer integrations in one service. Choose it for that breadth and its included status pages; look elsewhere if you need meaningful ongoing free coverage or a low-cost plan that combines several monitors with fast checks.
