Sensor-based · Cloud / On-prem · Free trial
The licensing unit is the thing to understand first about PRTG, because each monitored metric or interface counts as a sensor. The server component installs on Windows only, and protocol support covers SNMP, WMI, NetFlow, and REST APIs. SMB and mid-market teams often run it as one platform in place of separate network and server monitoring.
Host-based · Cloud · Free trial
Site24x7 puts servers, websites, networks, and cloud services under one monitoring platform from Zoho's portfolio, with pricing counted by host. At lower scale that predictability is where it competes favorably against Datadog and New Relic, which is why SMB and mid-market teams wanting broad coverage keep it in the running.
The rest of the website monitoring tools category, listed because the small business filter above did not select them. Worth reading when the highlighted options do not fit.
freemium
Incident management and uptime monitoring with built-in status pages and on-call scheduling.
Host-based · Cloud / On-prem · Free trial
Available both as a cloud-managed service and as software you run yourself, Checkmk covers estates from a few hundred hosts up to hundreds of thousands. Its auto-discovery engine cuts the initial configuration work that Nagios-derived alternatives demand. Billing is per host. That keeps the number tracking the environment in a way finance can predict as it grows.
Host-based · Cloud · Free trial
Collection runs through the Datadog Agent, which reaches cloud, on-prem and container environments, and more than 600 integrations handle the mapping work. Pricing is per host. Mid-market and enterprise teams with mixed infrastructure rarely stop at the infrastructure layer. Pairing it with Datadog APM and logs puts observability behind a single query interface.
freemium
Free uptime monitoring tool with multi-location checks, public status pages, and Slack/email alerts.
freemium
Uptime, blacklist, and server monitoring platform with free-tier support and global check locations.
Usage-based pricing · Cloud · Free trial
The pricing model is the genuine differentiator here. Charging for data ingested and seats used means teams monitoring many hosts at modest data volumes pay less than they would under per-host alternatives, a common pattern in host-heavy estates. High-cardinality environments flip that, and consumption needs careful modeling before any multi-year commitment.
subscription
Website uptime and performance monitoring with real-user monitoring and synthetic transaction checks.
freemium
Website monitoring platform with uptime, page speed, SSL, and domain expiry checks from global locations.
usage-based
Pay-per-check website monitoring with simple pricing, fast alerts, and a clean API.

Enterprise website monitoring with SLA reporting, real-user monitoring, and multi-step API checks.
freemium
Simple uptime monitoring service with 5-minute checks, status pages, and alerting for websites and APIs.
Transparent pricing with no "contact sales" gate, deployment measured in days rather than months, low administrative overhead, and enough automation to compensate for a small team. Avoid platforms that require dedicated admins or charge per-feature add-ons.
Pricing in this category varies widely by vendor and by what is counted (users, endpoints, or devices). Check each product's own pricing page for the current rate, and confirm which features sit behind paid add-ons before comparing totals.
Check the pricing curve rather than the entry price. Some products that are cheap at ten users become expensive at a hundred, and some free tiers end at a hard cap that forces a migration instead of an upgrade.
