HetrixTools

What HetrixTools actually is

HetrixTools is a monitoring platform with an unusual specialism: it checks whether your servers are up and whether your IP addresses are blacklisted, and it treats both as first-class products. Launched in May 2015 and built from scratch — including the support desk and billing system, by the company's own account — it is headquartered in Ramnicu Valcea, Romania, and has spent a decade becoming a fixture of the web hosting industry, where white-label uptime reports and blacklist alerts are part of daily operations.

The product splits into two subscriptions that you can buy separately or together. Uptime Monitor watches websites and servers: HTTP(S) checks every minute from a selection of twelve locations, plus a lightweight server agent reporting CPU, RAM, disk, network, RAID and drive health. Blacklist Monitor checks your IPs and domains against 94 IPv4 and domain blacklists — the same full list on every plan — and also watches Microsoft SNDS, which is the blacklist that actually reaches into Outlook deliverability. For hosting providers and email senders, that second product is the reason to be here; for everyone else it is a genuinely useful extra that most competitors do not offer at all.

Our editorial read: this is a tool built by practitioners for practitioners. The design language is "plans differ in how much you monitor, not in how well," and unlike most SaaS pricing pages, that claim survives reading the feature table.

Pricing: what you really pay

Both products have a free tier, and both are metered by quantity rather than feature gating.

Uptime Monitor: Free at $0 forever — 15 uptime monitors, 15 server monitors, 4 of 12 check locations, 15-day activity log. Professional is $9.95/month (or $99.95/year) for 30 + 30 monitors, 6 of 12 locations, 25 SMS credits and premium support. Business is $19.95/month (or $199.95/year) for 60 + 60 monitors, 9 of 12 locations, full white-label, 50 SMS credits. Enterprise is $49.95/month (or $499.95/year) for 200 + 200 monitors, all 12 locations, 20 sub-accounts and 125 SMS credits.

Blacklist Monitor: Free at $0 — 32 monitors checked every 24 hours. Personal is $9.95/month (or $99.95/year) for 256 monitors every 12 hours; Professional is $19.95/month (or $199.95/year) for 512 monitors every 8 hours; Business is $39.95/month (or $399.95/year) for 2,048 monitors; Enterprise is $99.95/month (or $999.95/year) for 8,192 monitors. Extra monitors can be added to any paid plan at the same rate.

Every price here is from HetrixTools' own pricing pages. Note that the two products bill separately: a hosting company running both at Business tier pays roughly $60/month, which is still modest versus the alternatives, but the "from $9.95" headline describes only one half of the platform. Extra phone/SMS credits cost $0.10 each on every plan.

The free tiers deserve emphasis. Fifteen uptime monitors with one-minute checks, fifteen server monitors, status pages and unlimited report history cost nothing, forever. That is enough to run a small hosting business or monitor a serious hobby fleet, and it is the reason the product spreads by word of mouth in forums where budgets are small and uptime matters.

Performance & infrastructure

The monitoring architecture is the feature list in practice. Checks run every minute from the locations your plan includes — and crucially, checks are taken from multiple locations throughout the minute specifically to rule out false alarms from a single flaky node. When something does go down, outage diagnostics include location fail logs and network diagnostics, so the first question ("is it me or them?") is answered before you log in. SSL validity and expiration, domain expiration and nameserver changes are monitored alongside uptime.

Alerting breadth is better than most full-stack observability suites: email, phone calls, SMS, Telegram, Slack, Discord, Microsoft Teams, Google Chat, Mattermost, RocketChat, PagerDuty, Opsgenie, ilert, VictorOps, Jira, Pushover, Pushbullet, ntfy.sh and webhooks. DND schedules and contact lists are standard. The API (v3, uncapped versus the older v1/v2 monthly limits) plus a newly added MCP interface means both scripts and AI agents can query monitor state directly.

For hosting companies, the white-label story is the operational win: status pages and uptime reports can carry your own branding and domains (3 white-label domains on Free, up to 20 on Enterprise), with private or public report sharing and unlimited report history on every plan. Combined with sub-accounts and the server agent's drive/RAID health reporting, HetrixTools covers much of what a small provider would otherwise assemble from Nagios, a blacklist checker and a status-page service.

We have not independently benchmarked check accuracy or detection latency; the one-minute cadence and multi-location confirmation are the vendor's published behavior, and user sentiment in the hosting community is strongly positive. For uptime comparisons of the hosts being monitored rather than the monitor itself, see /benchmarks.

Where it falls short

This is monitoring, not observability. There is no APM, no log aggregation, no distributed tracing, and no incident management platform — when a check fails you learn that it failed and roughly why, not where in your request path the latency came from. Teams wanting Datadog-class depth are shopping in the wrong aisle, and the honest comparison is that HetrixTools costs less per year than Datadog costs per day.

The two-product split means costs stack as you grow, and the blacklist meter deserves a look before you sign: check frequency varies by tier (24 hours on Free down to 8 hours on Professional) and queue priority (low to highest) affects how quickly large batches are processed. A hosting provider with thousands of IPs will care about both numbers more than about the monitor count.

Support is tiered — "normal" on Free, "premium" on paid — with no published response-time SLA or uptime guarantee for the service itself that we could find. For a monitoring tool, that is a familiar irony: the thing watching your uptime has no contractual uptime of its own. A decade of operation without visible incidents is the compensation, but it is worth stating plainly.

Finally, the interface is functional rather than beautiful, and the reporting history caps (15 to 90 days by tier) mean long-term trend analysis needs periodic export via the API.

The server agent deserves a closer look, because it is where HetrixTools quietly outgrows "uptime ping" territory. Installed once per monitored server, it reports CPU, RAM, disk usage, network throughput, RAID status and drive health back into the same dashboard as your HTTP checks. For a hosting provider, that turns the monitor into an early-warning system: a drive predicting failure or a disk filling up appears beside the uptime graph instead of in a separate tool nobody opened. It is not a full configuration-management stack, but for fleets of a few hundred machines it covers the alerting gap between "the site is down" and "the site will be down on Friday."

The reporting layer is built for sharing rather than for analysts. Uptime report history is unlimited on every plan, reports can be private or public, weekly and monthly email reports go out automatically, and multiple monitors can be bundled into one shareable status page. Web hosts typically embed these reports in client areas — the white-label domains exist precisely for that — and the pattern works: customers see uptime evidence with the provider's branding, and support teams send links instead of writing explanations.

We also like the product's honesty about its own limits. Queue priority is published per tier rather than hidden, blacklist check frequency is stated as a number of hours rather than "fast," and the free plan's lower priority is disclosed up front instead of discovered in production. That candor is worth as much as any single feature.

Who should pick this

Our pick for hosting providers, resellers and email senders: the blacklist monitoring — 94 blacklists plus Microsoft SNDS, with delisting alerts and white-label reports — is the feature that turns angry support tickets into proactive emails, and nothing else in this price class offers it this completely.

It is equally a good pick for freelancers and small teams who want one-minute uptime checks, server health and a status page without an enterprise monitoring bill. The free tier is genuinely usable, and the upgrade path is a simple count increase rather than a feature ransom.

Skip it if you need application performance monitoring, logs or incident response workflows; combine HetrixTools with a proper observability stack instead, or look at the /category/monitoring-hosting comparison for suites that do both.
