HetrixTools is built for people who run their own machines — server agents, resource metrics and blacklist monitoring for your mail reputation. It is genuinely good at that, and its free tier is more generous than most paid plans. What it does not do is tell you what changed on a page.

Is MonitoringDaddy a real HetrixTools alternative?
It depends what you are monitoring. If the answer is servers you own and mail reputation, HetrixTools is the right tool and its free tier costs nothing. If the answer is websites, certificates, domains, pages and scheduled jobs — watched from outside your infrastructure — that is what we do, from $5 a month.
Knowing a page responded is not the same as knowing what it says. A changed price, a removed clause or a quietly edited policy all return 200.
Server monitoring means deploying something and keeping it running. That is fine if you own the machine and unhelpful if you do not.
Enough to detect an outage, thin for confirming one.
Green marks the stronger option on that row. Third-party pricing and limits change without notice — treat the HetrixTools column as a starting point and confirm current figures on their site before you decide.

Every comparison page on the internet claims the author's product wins on everything. Here is where it does not.
If any of those are load-bearing for your team, staying put is the correct decision and this page has done its job. Monitoring you actually trust beats monitoring that is marginally cheaper.
Six monitor types and one dashboard. No add-on products, no separate SKUs for the features you assumed were included.
HTTP checks from external infrastructure, as often as every 60 seconds, with downtime and recovery alerts. See the uptime setup guide.
A dedicated monitor type with configurable advance warnings, so a certificate never lapses because nobody owned the renewal. See SSL expiry monitoring.
Registration expiry tracked as its own monitor, warning you months ahead. The outage nobody has a runbook for. See domain expiration monitoring.
Alert when a phrase appears or disappears on a page — defacement, stock changes, silent policy edits. See website change detection.
Watch a competitor or supplier price string and get told the moment it moves. See the price monitoring guide.
Public status pages included on every plan, hosted independently of your infrastructure so they stay up when you do not. See hosted status pages.
Alerts from any of these can be routed to email, Slack, Microsoft Teams, Discord, Telegram, Flock or a generic webhook, and a single monitor can carry several channels at once. Everything is available through the REST API on paid plans, so monitors can be created and torn down programmatically rather than clicked through a form.
Flat monthly tiers. No per-seat charges, no credit top-ups, no usage meters — the number below is the whole bill.
| Plan | Monitors | Fastest interval | Alert channels | API | Price |
|---|---|---|---|---|---|
| Free | 1 | Every 30 minutes | — | $0 | |
| Founding Member first 20 only | 25 | Every 5 minutes | Email + webhook & chat | Yes | $5/mo |
| Basic | 10 | Every 10 minutes | Email + webhook & chat | Yes | $8/mo |
| Growth | 50 | Every 5 minutes | Email + webhook & chat | Yes | $19/mo |
| Pro | 100 | Every 60 seconds | Email + webhook & chat | Yes | $34/mo |
Annual billing is cheaper on every paid tier. The pricing page is the authoritative list.
There is no automated importer — monitors are re-created by hand, or scripted through the API on paid plans. Budget about a minute per monitor.
List every active check: URL, interval, condition and alert recipients. Most teams find monitors nobody needs any more.
Start with revenue-critical URLs. Set the interval, add the condition, attach the channels your team already watches.
Keep HetrixTools live while the new monitors settle. Compare alerts and confirm nothing is missing.
Move any public status page across, confirm a clean week of overlap, then cancel the old subscription.
This page is written by the team that builds MonitoringDaddy, so treat it as an informed argument rather than a neutral audit. What we can promise is that the claims about our own product are checked against what the software actually does, and the rows where HetrixTools is stronger are marked as such rather than quietly omitted.
Details about HetrixTools come from their public pricing and documentation at the time of writing. Monitoring vendors change plan limits and prices frequently and without announcement, so every third-party figure here carries a "verify on their site" caveat and you should take it seriously before making a decision on cost.
One thing worth stating plainly, because most comparison pages fudge it: MonitoringDaddy checks run from our own infrastructure, which is external to yours, but from a single origin rather than a global probe network. That is enough to catch outages and content changes independently of your stack. It is not enough to tell you a site is down in Frankfurt but up in Ohio. If regional verification is a hard requirement, a larger platform will serve you better and we would rather you knew that now.

Every recorded change is compared word by word and kept with a before-and-after image. This is the real output, shown with worked example data.
Price fell from $49 to $39, and an annual discount was added.
The item is available again and the basket button returned.
A new subprocessor was added in another jurisdiction.
The free plan sends to one email address. Every paid plan adds the chat and webhook channels below, with 2 to 10 destinations depending on the plan. However many alerts you receive, the price does not change — nothing here is metered or charged per alert.
There are no voice calls and no SMS. If a phone call at 3am is a hard requirement, say so before you subscribe — we would rather tell you now than refund you later.
No. HetrixTools has a genuinely generous one — 15 uptime monitors, 15 server monitors and blacklist monitoring, lifetime free. For a personal server that is the better deal and we would say so.
No. If your mail server IP lands on a blocklist, HetrixTools will tell you and we will not. It is a real gap and worth knowing before switching.
No. We check things from outside — no agent, nothing installed. That means we cannot see CPU or disk, and it also means there is nothing to maintain.
We fetch the page, compare it with the last version and tell you what actually changed — with a region you choose to watch, rules for ignoring the parts that always move, and before and after images. HetrixTools does not do this.
Yes. SSL is a standalone monitor type, so you can watch a certificate without an uptime monitor on the same host, with a warning window from 1 to 60 days.
Their free tier beats any paid plan for cost. Among paid plans they start around $5.95 and we start at $5 for 25 monitors, so the paid entry prices are close and the difference is what a monitor can be.
No. Every check runs from our infrastructure, which is also why an outage at your host does not take the monitoring down with it.
Plenty of people reasonably would. They cover servers and mail reputation; we cover sites, certificates, domains, page content and jobs. The overlap is smaller than the category suggests.
