Uptime Monitor vs HetrixTools

HetrixTools is an uptime and blacklist monitoring platform that has built a loyal following among web hosts, agencies, and IT professionals. Uptime Monitor is a focused uptime monitoring tool for small businesses.

Both tools check if your websites are up. HetrixTools adds blacklist monitoring and server monitoring on top. Here is how they compare.

The Quick Version

HetrixTools offers uptime monitoring alongside IP/domain blacklist monitoring and server resource monitoring. Free tier includes 15 monitors. Paid plans start at around $10/month. The blacklist monitoring feature is its standout differentiator — it checks if your IPs or domains appear on spam/abuse blacklists.

Uptime Monitor checks your websites from multiple global locations every minute and sends instant alerts when something goes down. $9/month for unlimited sites.

If you need blacklist monitoring alongside uptime checks, HetrixTools is one of the few tools that bundles both. If you just need reliable uptime monitoring with unlimited sites at a flat rate, Uptime Monitor keeps things simpler.

Pricing Comparison

Uptime Monitor:

Free: 3 sites, email alerts
Pro: $9/month for unlimited sites, 1-minute checks, all alert channels

HetrixTools:

Free: 15 uptime monitors, 1 server monitor
Basic: ~$10/month for 30 uptime monitors, 5 server monitors
Standard: ~$20/month for 60 uptime monitors, 10 server monitors
Advanced: ~$50/month for 200 uptime monitors, 25 server monitors

Pricing at Scale

At small scale, HetrixTools is competitive. The free tier with 15 monitors is generous. But as your monitoring needs grow:

15 sites: HetrixTools free vs Uptime Monitor $9/mo
30 sites: HetrixTools ~$10/mo vs Uptime Monitor $9/mo
60 sites: HetrixTools ~$20/mo vs Uptime Monitor $9/mo
120 sites: HetrixTools ~$50/mo vs Uptime Monitor $9/mo

The pricing gap widens as your site count grows. For agencies or businesses with many sites, the difference becomes significant over a year.

Monitor limits apply across types

HetrixTools' monitor count covers uptime monitors, and server monitors have separate limits. If you use both features, you need to factor both into your plan choice.

When to Choose HetrixTools

You need blacklist monitoring

This is HetrixTools' specialty. If your business sends email or hosts services where IP reputation matters, blacklist monitoring is genuinely valuable. HetrixTools checks your IPs against 100+ blacklists.

You need server resource monitoring

HetrixTools offers agent-based server monitoring that tracks CPU, memory, disk, and network usage. Useful if you manage your own servers.

You have fewer than 15 sites

The free tier covers 15 uptime monitors, which is generous enough for many small businesses.

You want uptime + blacklist in one tool

Fewer vendors, one dashboard, integrated alerts.

HetrixTools is a solid product with features that matter for hosting companies, MSPs, and anyone who cares about IP reputation. The blacklist monitoring feature is hard to find elsewhere at this price point.

Need unlimited uptime monitoring?

No monitor limits. $9/month flat rate for all your sites.

When to Choose Uptime Monitor

You have many sites to monitor

Unlimited sites at $9/month beats per-monitor pricing at any meaningful scale.

You do not need blacklist monitoring

Most small businesses running standard websites do not need IP blacklist checks. If that is not a concern, you do not need to pay for it.

You want the simplest setup possible

Add a URL, pick your alerts, done. No server agents, no blacklist configuration.

You want predictable costs

One price, unlimited sites. No counting monitors or calculating tiers.

The Blacklist Question

HetrixTools' blacklist monitoring is genuinely unique in this price range. If any of these apply to you, it matters:

You run an email server or bulk email service
You host websites for clients and need to protect IP reputation
You operate a VPS or dedicated server hosting business
You have experienced email deliverability issues

If none of those apply — if you are a small business with a marketing website hosted on Squarespace, WordPress, or Shopify — blacklist monitoring is not something you need. Your hosting provider handles IP reputation for you.

Be honest about whether blacklist monitoring solves a problem you actually have, or if it sounds useful in theory but would sit unused in practice.

HetrixTools' Free Tier

HetrixTools offers 15 free uptime monitors. That is one of the more generous free tiers in the monitoring space.

For personal projects, side businesses, or small portfolios, 15 monitors may be all you need. The free tier does have limitations — check intervals are less frequent, and some features are restricted — but for basic "is my site up?" monitoring, it works.

The question is what happens when you outgrow 15 monitors. The jump to paid plans means navigating monitor-count tiers, and the cost per monitor increases as you scale.

Server Monitoring

HetrixTools includes server monitoring with an installable agent. This tracks CPU usage, memory, disk space, network traffic, and running processes on your servers.

If you manage your own servers (VPS, dedicated, or on-premise), this is useful. You get uptime monitoring and server health in one dashboard.

Uptime Monitor does not offer server monitoring. It checks your websites from the outside, not your servers from the inside. For most small businesses using managed hosting (shared hosting, cloud platforms, or SaaS builders), external uptime monitoring is all they need. You do not need server monitoring if you do not manage servers.

The Niche Factor

HetrixTools is less well-known than UptimeRobot or Pingdom, but it has a dedicated community — particularly among hosting providers and system administrators. That niche focus means the features are tailored for people who manage infrastructure professionally.

Uptime Monitor is built for a different niche: small business owners, freelancers, and agencies who need monitoring but do not manage infrastructure. Different audiences, different priorities.

Integration and Alerts

Both tools support common notification channels. HetrixTools integrates with email, Slack, Telegram, Discord, PagerDuty, and more. Uptime Monitor supports email, SMS, and Slack.

HetrixTools has a wider integration list, reflecting its appeal to DevOps teams who use diverse notification workflows. Uptime Monitor covers the channels that most small businesses actually use.

If you need alerts sent to Telegram, Discord, or PagerDuty, HetrixTools has an edge. If email, SMS, and Slack cover your needs, both tools work fine.

Our Honest Take

HetrixTools is a well-built product that serves its audience well. The blacklist monitoring feature is genuinely differentiated — if you need it, few tools offer it at this price. Server monitoring is a nice addition for people who manage their own infrastructure.

But for small businesses that just need uptime monitoring, HetrixTools' extra features are extras you do not need, and the monitor-count pricing means costs climb as you grow.

Uptime Monitor does one thing: checks your sites and alerts you when they go down. Unlimited sites at $9/month. No monitor limits, no blacklist features you will not use, no server agents to install.

If you know you need blacklist monitoring, go with HetrixTools. If you just need uptime checks, keep it simple.
