PRTG licenses by sensor (about 5 to 10 sensors per device) on published tiers sold as 3-year subscriptions billed annually, from PRTG 500 at $200 per month (around 50 devices) to PRTG 10000 at $1,642 per month (around 1,000 devices). Since July 2024, new PRTG licenses are subscription only, with no monthly or 1-year option for the on-premises product. Domotz prices differently: Collector-based pricing starts at $35 per Collector per month, with volume discounts available and no sensor counting.

What's the difference between Domotz and PRTG?

Both monitor networks, but they're built differently. Deployment: Domotz is cloud-based with a Collector at each site; PRTG runs on an on-premises Windows server (or PRTG Hosted Monitor with a Windows probe on site). Price: Domotz starts at $35 per Collector per month with no annual commitment; PRTG prices per sensor on 3-year subscription tiers. Features: Domotz identifies devices by MAC address for better accuracy than PRTG's IP-based discovery, and includes power management, configuration management, and remote access. PRTG offers deeper metric granularity through 250+ sensor types. AI: Domotz provides both an in-app AI assistant and an MCP server; PRTG offers no AI assistant and no published MCP server.

Is PRTG good for MSPs?

PRTG can work for MSPs through Paessler's MSP program, which sells sensors in blocks of 10,000 and markets a multi-tenant MSP edition. Domotz is multi-tenant by default: every site appears in one dashboard with role-based access, and the same access controls govern what your AI agents can do through the Domotz MCP server. Pricing starts at $35 per Collector per month with no minimum purchase. Teams that want to deploy to every customer site at a lower cost with no Windows infrastructure tend to prefer Domotz.

Does PRTG have a free version?

Yes. PRTG offers a free version for up to 100 sensors with no time limit, plus a 30-day trial of the on-premises product (PRTG Hosted Monitor trials run 10 days). Domotz offers a 14-day trial with no credit card required, and every discovered device gets full functionality from the first day.

Quick answer

Domotz and PRTG differ in the ways that matter most: how you deploy, what you pay, and what you can do with it.

Deployment. Domotz is cloud-based. You install a Collector at a site (15+ software options or the Domotz Box appliance) and the site is monitored in about 15 minutes, with nothing to host or patch. PRTG runs on a Windows server you maintain, and PRTG Hosted Monitor still needs a Windows probe on each network.

Price. Domotz charges per Collector, starting at $35 per Collector per month, with volume discounts available and no annual commitment. PRTG licenses by sensor (about 5 to 10 sensors per device) on published tiers from PRTG 500 at $200 per month to PRTG 10000 at $1,642 per month, sold as 3-year subscriptions billed annually. Growing past a tier means paying for the next one.

Functionality. Domotz identifies devices by MAC address, so your inventory stays accurate as IP addresses change. PRTG discovers by IP range scan, uses MAC addresses only to pick vendor icons, and doesn't track IP changes automatically. Domotz also covers the work that comes after discovery, with power management, configuration backup and restore, and remote access built in, and exposes monitoring and management to AI agents through the Domotz MCP server. PRTG's strength is depth of metrics: 250+ sensor types for teams that want to monitor almost anything, provided they can run the infrastructure and tune the sensors. PRTG has no in-app AI assistant and no published MCP server.

How Domotz and PRTG Compare

Pricing model, deployment, and management.

	Domotz	PRTG
Pricing	$$ Per Collector pricing Pricing starts at $35 per Collector per month with volume discounts available.	$$$ Per sensor, 3-year term Published tiers from PRTG 500 at $200 per month (about 50 devices) to PRTG 10000 at $1,642 per month, sold as 3-year subscriptions billed annually. No monthly or 1-year option for on-premises PRTG.
Cloud-Based Platform	Nothing to host. Domotz runs the platform; you run a Collector at each site.	PRTG runs on a Windows server you maintain. PRTG Hosted Monitor moves the core server to Paessler's cloud but still needs a Windows probe on each network.
Software Deployment Options	15+ Options Windows, Ubuntu, Synology, VMware, Hyper-V, Raspberry Pi, Docker, and more.	Windows Server (core) The PRTG core server runs on Windows only. Remote probes can also run on Linux, Raspberry Pi, Docker, and NAS devices.
Hardware Deployment Option	Domotz Box appliance is available to plug into the network.	No first-party hardware appliance option.
MAC Address Device Identification	MAC-based identification ensures accuracy, even with IP changes.	Discovers devices by IP range scan. MAC addresses are used only to assign vendor icons, and a changed IP address is not tracked automatically.
Custom Drivers	Open development framework to deploy custom drivers for metrics and automation on any IP device.	Custom sensors via EXE and script, Python, SSH, REST, and SNMP. Each custom sensor counts against the licensed sensor total.
Power Management	Built-in remote power control with on/off and cycling.	Monitoring only. No native power control; SNMP set commands require a custom script.
Network Topology	Real-time topology mapping and visualization.	Manual map designer in core PRTG. Automatic Layer 2 and Layer 3 maps require the separately priced PRTG UVexplorer add-on.
Configuration Management	Automated configuration backup and restore for network gear, expandable to any device through the Open Development Framework.	Not in core PRTG. The PRTG UVexplorer add-on backs up and compares configurations; restore is not documented.
Remote Access	Secure tunnels (HTTP/HTTPS, SSH, RDP, Telnet, TCP) plus VPN on Demand for full LAN access.	No built-in remote access. Paessler has said SSH and Telnet sessions won't be added to PRTG.
Meaningful Alerts	Domotz delivers reliable, customizable alerts that keep teams focused.	Reviewers on G2 describe notification floods during spikes, alert fatigue, and a steep learning curve.
AI Operability	Both an in-app AI assistant and an MCP server for programmatic monitoring and management. The MCP server is included in every subscription.	No in-app AI assistant and no published MCP server. Paessler's AI work is limited to anomaly detection and baselines inside PRTG.
Quality of Support (*according to customer reviews on G2)	9.5	8.9

Audience fit

Which Fits Which Team

Where Domotz fits

Teams that want cloud-based monitoring and management across many sites at a lower price, with no Windows server to maintain, no 3-year commitment, more accurate device identification, and AI operability through the Domotz MCP server.

Where PRTG fits

Single-site, OT, or industrial teams that prefer to run their monitoring on their own Windows infrastructure on a 3-year term.

Watch for

What to Watch For

PRTG licenses by sensor, not by device. The 5 to 10 sensors-per-device estimate assumes standard monitoring depth, so more granular configurations (extra SNMP OIDs, WMI counters, or application sensors per device) use up a tier faster than the device count suggests. Tiers run in fixed steps, and every new on-premises license is a 3-year subscription billed annually. Domotz pricing starts at $35 per Collector per month, so adding devices or sensors to a site doesn't change what you pay.

Bottom line

The Bottom Line

Domotz for teams that want cloud-based monitoring and management they can deploy everywhere at a lower cost, with no infrastructure, no long-term commitment, and an MCP server included. PRTG for teams that need maximum metric granularity and are set up to run and maintain it on a 3-year term.
