HetrixTools and UptimeRobot are both popular budget monitoring tools, but they take very different approaches. UptimeRobot focuses on straightforward uptime monitoring with a clean interface. HetrixTools bundles uptime monitoring with server monitoring, blacklist monitoring, and more features per dollar.
This guide compares HetrixTools and UptimeRobot on what actually matters when choosing between them: free plan limits, paid pricing, monitor types, alert channels, status pages, and the tradeoffs you will run into at each tier. We also cover a third option that combines the best of both.
Free Plans Compared
Both tools offer a free tier, but with very different structures and restrictions. Here is what each gives you at zero cost.
| Feature | HetrixTools Free | UptimeRobot Free |
|---|---|---|
| Uptime monitors | 15 | 50 |
| Check interval | 1 minute | 5 minutes |
| Server monitors | 15 | Not available |
| Blacklist monitors | 32 | Not available |
| SSL monitoring | Included | Paid only |
| Status pages | Unlimited | 1 (branded) |
| Monitoring locations | 4 | Not specified |
| SMS credits | 0 ($0.20 each extra) | 0 |
| Commercial use | Yes | No (personal only) |
| Login requirement | Every 90 days | None |
HetrixTools gives you fewer uptime monitors (15 vs 50), but the monitors you do get run at 1-minute intervals instead of 5 minutes. That is a significant difference. A 5-minute check means your site could be down for up to 5 minutes before the first check even notices. At 1 minute, you catch problems much faster.
HetrixTools also bundles server monitoring (CPU, RAM, disk via installed agents) and blacklist monitoring (checks if your IP is listed on spam blacklists) on the free plan. UptimeRobot only does uptime monitoring.
UptimeRobot Free Plan: Non-Commercial Use Only
Since October 2024, UptimeRobot's free plan is restricted to personal, non-commercial use. If you are using it for a business, client site, or any revenue-generating project, you must upgrade to a paid plan. Open-source, educational, and nonprofit projects are exempt.
HetrixTools does require you to log in at least once every 90 days on the free plan, or your account is deactivated. UptimeRobot has no such requirement. This is worth noting if you set up monitoring and then forget about it for months.
Bottom line: HetrixTools offers more value per free monitor (faster checks, SSL, server monitoring, blacklist monitoring, unlimited status pages). UptimeRobot gives you more monitors (50 vs 15) but restricts commercial use. For a full breakdown of all free options, see our best free website monitoring tools comparison.
Paid Plans Compared
Once you need more monitors or faster checks, the pricing structures diverge. Here is what you pay at each tier.
HetrixTools Paid Plans
| Plan | Monthly Price | Uptime Monitors | Interval | SMS Credits/mo |
|---|---|---|---|---|
| Professional | $9.95/mo | 30 | 1 min | 25 |
| Business | $19.95/mo | 60 | 1 min | 50 |
| Enterprise | $49.95/mo | 200 | 1 min | 125 |
UptimeRobot Paid Plans
| Plan | Monthly Price | Uptime Monitors | Interval | Team Members |
|---|---|---|---|---|
| Solo | $8/mo | 10 | 60 sec | 0 |
| Team | $34/mo | 100 | 60 sec | 3 ($15/mo extra each) |
| Enterprise | $64/mo | 200 | 30 sec | 5 |
At the entry level, UptimeRobot's Solo plan ($8/month) is cheaper than HetrixTools Professional ($9.95/month), but UptimeRobot only gives you 10 monitors versus HetrixTools' 30. That means UptimeRobot actually costs more per monitor.
At 60 monitors, HetrixTools Business ($19.95/month) is the only option that does not require an Enterprise tier. UptimeRobot's Team plan gives you 100 monitors for $34/month, but if you only need 60, you are paying for 40 monitors you do not use.
At 200 monitors, both charge roughly $50 to $64/month. HetrixTools includes server monitoring and blacklist monitoring at every tier. UptimeRobot does not offer either. For a broader look at affordable monitoring, see our cheap uptime monitoring guide.
Feature Comparison
This is where the two tools differ most. HetrixTools is a multi-product monitoring platform. UptimeRobot is a focused uptime monitoring tool.
| Feature | HetrixTools | UptimeRobot |
|---|---|---|
| HTTP/HTTPS monitoring | Yes | Yes |
| Ping monitoring | Yes | Yes |
| Port monitoring | Yes | Yes |
| Keyword monitoring | Yes | Yes |
| SSL certificate monitoring | All plans | Paid only |
| Domain expiration monitoring | Yes | Yes (paid) |
| Heartbeat/cron monitoring | No | Yes |
| Server monitoring (agent) | Yes (Linux, macOS, Windows) | No |
| Blacklist monitoring | Yes (94 blacklists) | No |
| Nameserver change detection | Yes | No |
| Automatic MTR/PING traces | Yes (on outage) | No |
| Multi-location monitoring | 4 to 12 locations | Multiple locations |
| Uptime history | Unlimited | Varies by plan |
HetrixTools clearly wins on feature breadth. Server monitoring with installable agents, IP blacklist scanning across 94 databases, automatic network trace generation during outages, and nameserver change detection for domain hijacking protection are all features UptimeRobot simply does not have.
UptimeRobot's main feature advantage is heartbeat (cron job) monitoring. If you run scheduled tasks and need dead man's switch monitoring, UptimeRobot supports it natively. HetrixTools does not. For more on this, see our cron job monitoring guide.
HetrixTools bundles uptime monitoring, server monitoring, and blacklist monitoring into a single platform.
Alert Channels
Alert delivery is one area where HetrixTools has a clear edge. The number of integrations available on HetrixTools, even on the free plan, is significantly larger.
| Alert Channel | HetrixTools | UptimeRobot |
|---|---|---|
| All plans | All plans | |
| SMS | Paid credits ($0.20 each free, $0.12+ paid) | Paid credits (one-time bundle) |
| Phone calls | Paid credits | Paid credits |
| Slack | All plans | Solo+ ($8/mo) |
| Discord | All plans | Not available |
| Telegram | All plans | Solo+ ($8/mo) |
| Microsoft Teams | All plans | Solo+ ($8/mo) |
| Webhooks | All plans | Team+ ($34/mo) |
| PagerDuty | All plans | Team+ ($34/mo) |
| Google Chat | All plans | Not available |
HetrixTools includes Slack, Discord, Telegram, Microsoft Teams, Google Chat, PagerDuty, Opsgenie, webhooks, and more on every plan, including free. UptimeRobot locks Slack and Telegram behind the Solo plan ($8/month) and webhooks and PagerDuty behind the Team plan ($34/month).
For SMS, both tools use a credit system. HetrixTools gives paid plan users a monthly SMS credit allowance (25, 50, or 125 depending on the tier). UptimeRobot gives a one-time welcome bundle of SMS credits that do not renew. Additional credits cost roughly $0.15 to $0.20 each on both platforms. For more on alert channel options, see our website downtime alerts guide.
UptimeRobot focuses on straightforward uptime monitoring with a clean, simple interface.
Status Pages
Both tools include status pages, but the implementations differ.
HetrixTools includes unlimited status pages on every plan, including free. You can use custom (white label) domains on all plans as well, with 3 white label domains on the free plan scaling up to 20 on Enterprise. Status pages auto-update based on your monitor data.
UptimeRobot includes 1 branded status page on the free plan, 3 on Solo ($8/month), 100 on Team ($34/month), and unlimited on Enterprise ($64/month). Custom domain support is not available on the free plan.
If status pages matter to you, HetrixTools is the clear winner here. Unlimited pages with custom domains, even on the free tier, is unusually generous. Most competitors charge extra for custom domain support. For a deeper look at status page tools, see our best monitoring tools with built-in status pages guide.
Who Should Use Which
Choose HetrixTools if:
- You need server monitoring alongside uptime monitoring. HetrixTools is the only budget tool that includes agent-based server monitoring (CPU, RAM, disk, network) on every plan.
- You run email servers or care about IP reputation. Blacklist monitoring across 94 databases is unique to HetrixTools at this price point.
- You want faster free checks. 1-minute intervals on the free plan versus 5 minutes on UptimeRobot.
- You need lots of integrations on a budget. Slack, Discord, Telegram, PagerDuty, webhooks, and more on every plan, including free.
- You need unlimited status pages. Available on all plans, including free, with custom domain support.
Choose UptimeRobot if:
- You need the most free monitors possible. 50 monitors on the free plan versus 15 on HetrixTools (if your use is non-commercial).
- You want the simplest interface. UptimeRobot is cleaner and easier to navigate. HetrixTools packs more features into a denser UI.
- You need heartbeat/cron monitoring. UptimeRobot supports dead man's switch monitoring natively. HetrixTools does not.
- You prefer a set-and-forget approach. No 90-day login requirement on the free plan.
Consider Notifier as an Alternative
If neither HetrixTools nor UptimeRobot feels quite right, Notifier offers a cleaner experience with competitive pricing. Here is how the three tools compare.
| What Matters | HetrixTools | UptimeRobot | Notifier |
|---|---|---|---|
| Free monitors | 15 | 50 (non-commercial) | 10 (commercial OK) |
| Free SSL monitoring | Yes | No | All monitors |
| Free status pages | Unlimited | 1 | 5 |
| Cheapest paid plan | $9.95/mo (30 monitors) | $8/mo (10 monitors) | $4/mo (20 monitors) |
| 100 monitors price | $49.95/mo | $34/mo | $19/mo |
| Fastest check interval | 1 min (all plans) | 30 sec ($64/mo) | 30 sec ($19/mo) |
| Slack integration | All plans | Solo+ ($8/mo) | All plans |
| SMS/phone alerts | Credit system | Credit system (one-time) | Credit system (all plans) |
Notifier's monitoring dashboard. Clean interface with uptime history, response time, and status at a glance.
Notifier's entry-level pricing is hard to beat. The Solo plan at $4/month gives you 20 monitors with 1-minute checks, custom domain status pages, and SMS and phone call alerts. That is half the price of UptimeRobot's Solo plan and less than half the price of HetrixTools' Professional plan.
At 100 monitors, Notifier's Team plan ($19/month) includes 30-second check intervals, 50 status pages, 3 team members, and SSL certificate monitoring on every monitor. HetrixTools charges $49.95/month for their Enterprise plan to get close to 100 monitors (they cap at 60 on Business and jump to 200 on Enterprise). UptimeRobot charges $34/month for 100 monitors.
Notifier does not have server monitoring or blacklist monitoring like HetrixTools. If you need those features, HetrixTools is the better choice. But if you primarily need uptime, SSL, and DNS monitoring with fast alerts and status pages, Notifier delivers more value per dollar than either competitor.
Notifier's pricing. The Team plan at $19/month undercuts both HetrixTools and UptimeRobot at the 100-monitor tier.
Frequently Asked Questions
Is HetrixTools or UptimeRobot better for a small business?
For a small business, HetrixTools is the safer free option because it allows commercial use. UptimeRobot's free plan is restricted to non-commercial projects since October 2024. HetrixTools also gives you faster 1-minute checks, SSL monitoring, and more integrations on the free plan. The tradeoff is fewer monitors (15 vs 50) and a 90-day login requirement.
Does HetrixTools have a login requirement on the free plan?
Yes. You must log in to your HetrixTools dashboard at least once every 90 days on the free plan, or your account will be deactivated. Upgrading to any paid plan removes this requirement. UptimeRobot has no login requirement on their free plan.
Can I use UptimeRobot's free plan for my business website?
No. Since October 2024, UptimeRobot's free plan is limited to personal, non-commercial use. Business, client, or revenue-generating projects require a paid plan starting at $8/month. Open-source, educational, and nonprofit projects are exempt.
Which tool has better alert integrations?
HetrixTools by a wide margin. It includes Slack, Discord, Telegram, Microsoft Teams, Google Chat, PagerDuty, Opsgenie, webhooks, and more on every plan, including free. UptimeRobot locks Slack and Telegram behind the Solo plan ($8/month) and webhooks and PagerDuty behind the Team plan ($34/month). Notifier includes Slack on all plans, including free.
Does HetrixTools offer cron job or heartbeat monitoring?
No. HetrixTools does not support heartbeat or dead man's switch monitoring. If you need to monitor cron jobs or scheduled tasks, UptimeRobot is the better choice between these two. See our cron job monitoring guide for more options.
Which is cheaper at 100 monitors?
HetrixTools does not have a 100-monitor plan. Their Business plan offers 60 monitors for $19.95/month, and their Enterprise plan jumps to 200 monitors for $49.95/month. UptimeRobot offers 100 monitors on the Team plan for $34/month. Notifier's Team plan covers 100 monitors for $19/month with 30-second checks and 50 status pages.
