Best RMM Tools for MSPs
The RMM platforms MSPs and IT teams actually run — compared on monitoring depth, patching, remote access, automation, multi-tenancy and pricing.
RMM is the tool that decides whether supporting 500 machines takes five engineers or one. The differences between platforms are less about features on a page and more about pricing model, agent quality and how much automation you can realistically build.
Basics
What RMM tools do
RMM tools install an agent on every device you support, watch its health continuously, and let you patch, script and remote-control it from one console — the capabilities below define the category, and every product in this guide covers them to some degree. The differences worth paying for sit in the depth: how good the agent is on each OS, how much patching is genuinely automated, and how much of the workflow an MSP can run per client without the data bleeding together.
- Continuous endpoint health monitoring with alerting
- Patch management for OS and third-party applications
- Remote access, attended and unattended
- Scripting and automation across device groups
- Hardware and software inventory collected automatically
- Per-client reporting and SLA evidence (essential for MSPs)
The options
The best RMM tools, platform by platform
Seven platforms cover the realistic shortlist: NinjaOne, Datto RMM, Atera, ConnectWise Automate, N-able N-central, Action1 and Infronest. For each one below: what it is genuinely good at, where it is limited, who it fits, and how it charges. On pricing we state the model only — most RMM vendors quote rather than publish, so treat every rate you see online as negotiable and check the vendor directly.
NinjaOne
Strengths. NinjaOne has become the default mid-market recommendation for a reason: a fast, modern console, strong OS and third-party patching that works without a scripting project, solid automation that non-scripters can actually build, and agents for Windows, macOS and Linux. Onboarding time from purchase to useful monitoring is among the shortest in the category.
Limits. Per-endpoint pricing scales with the fleet, which gets expensive when you manage thousands of low-value machines. Deep customisation — the kind ConnectWise Automate lives on — is more constrained, and complex multi-step automations eventually hit the platform's guardrails.
Who it fits and pricing model. Mid-size MSPs and internal IT teams that value time-to-value over maximum configurability. Per-endpoint, quote-based pricing; published price varies — check vendor.
Datto RMM
Strengths. Datto RMM is a mature cloud platform with deep policy-driven automation, a large component library for packaged scripts and monitors, and tight integration with the wider Datto ecosystem — backup and continuity products and the Autotask PSA — which is a real operational advantage for MSPs already invested there.
Limits. It is enterprise-oriented in both contract shape and complexity: third-party patching is component-driven and takes more building than NinjaOne's out-of-the-box coverage, and realising the platform's value assumes someone owns it as a discipline rather than a side duty.
Who it fits and pricing model. Larger MSPs, particularly those already running Datto backup or Autotask. Per-endpoint, quote-based pricing; published price varies — check vendor.
Atera
Strengths. Atera breaks the category's pricing convention: you pay per technician, not per endpoint, so the cost of managing 200 devices and 2,000 devices with the same two engineers is identical. That single decision makes it dramatically economical for small teams managing large fleets. The platform bundles helpdesk and billing features alongside RMM, and OS patching is complemented by third-party application coverage through Chocolatey and Homebrew integrations.
Limits. Automation and policy depth run behind ConnectWise Automate and Datto RMM, the Windows agent is clearly the first-class citizen with macOS and Linux thinner, and the per-technician model loses its magic if you staff many part-time technicians — the maths only works when few people manage many machines.
Who it fits and pricing model. Small MSPs and internal IT teams with a high device-to-engineer ratio. Per-technician subscription tiers; published price varies — check vendor.
ConnectWise Automate
Strengths. ConnectWise Automate remains the most powerful automation engine in the category: near-unlimited scripting, granular monitors, and a partner ecosystem that has already built most of what you will ever need. Large MSPs run tens of thousands of endpoints on it, patching OS and third-party software through heavily customised, script-driven policies, integrated with the ConnectWise PSA stack.
Limits. The learning curve is the steepest here, parts of the console show their age, and the platform rewards — effectively requires — a dedicated administrator who treats Automate as their craft. Small teams that buy it for the power tend to use a fraction of it while paying for all of it.
Who it fits and pricing model. Large MSPs with dedicated automation engineers and process maturity. Quote-based, typically per endpoint; published price varies — check vendor.
N-able N-central
Strengths. N-able's N-central is long-established MSP tooling with broad coverage: endpoint monitoring, OS and third-party patch management, automation policies, and notably deep network-device monitoring alongside the endpoint story. Its sibling product N-sight serves smaller operations, giving a growth path within one vendor.
Limits. Breadth over polish — administration carries more overhead than the newer cloud-native rivals, and teams migrating between N-sight and N-central should scope that move realistically rather than assuming a toggle.
Who it fits and pricing model. Established MSPs with mixed fleets and real network-monitoring requirements. Per-endpoint, quote-based pricing; published price varies — check vendor.
Action1
Strengths. Action1 is cloud-native and patching-first: automated OS and third-party patch management with vulnerability visibility, deployable in an afternoon, with a free tier that makes it the cheapest credible way for a small estate to get real patch compliance. For teams whose actual pain is patching rather than full RMM, that focus is a feature.
Limits. It is narrower than the full RMM suites — the centre of gravity is patch management and endpoint essentials rather than broad monitoring, automation and PSA workflows — and it is Windows-first in depth. Evaluate it against your patching problem, not against a full-suite checklist it is not trying to win.
Who it fits and pricing model. Patch-compliance-driven teams and budget-conscious small estates. Per-endpoint pricing with a free tier for small estates; published price varies — check vendor.
Infronest
Disclosure: Infronest is our own product. We include it because it genuinely competes in this category; evaluate it with the same criteria as every other tool.
Strengths. Infronest's RMM and endpoint management runs inside the same tenant-isolated workspace as server and network monitoring, IT assets, helpdesk, patch management and VAPT — so an alert, the device it came from, the ticket it raised and the asset record are one connected story rather than four consoles. Agents cover Windows, macOS and Linux; patching covers OS and third-party applications through the built-in patch module; and MSPs get genuine per-tenant isolation per client, not a filtered view.
Limits. As a standalone RMM it is younger than everything above, with a smaller integration ecosystem, and it will not win a feature-by-feature automation contest with ConnectWise Automate. The case for it is consolidation: it replaces the RMM plus the separate ticketing, asset and patching tools around it.
Who it fits and pricing model. MSPs and internal IT teams consolidating their stack, and mixed Windows/Linux estates. Flat per-user pricing published on the pricing page, with a 14-day free trial.

RMM tools comparison table
The table condenses the entries above to the four decisions that shortlist an RMM: how it charges, who it serves, and how far its patching actually reaches.
RMM platforms compared on pricing model, fit and patch coverage
| Platform | Pricing model | Best for | Patch coverage |
|---|---|---|---|
| NinjaOne | Per endpoint | Mid-size MSPs wanting fast time-to-value | OS + third-party |
| Datto RMM | Per endpoint | Larger MSPs in the Datto/Autotask ecosystem | OS + third-party (component-driven) |
| Atera | Per technician | Small teams managing large fleets | OS + third-party via integrations |
| ConnectWise Automate | Per endpoint (quote) | Large MSPs with automation engineers | OS + third-party, script-driven |

Pricing models matter more than feature lists
RMM pricing usually follows one of two shapes, and the right choice depends on your ratio of devices to engineers.
Per-endpoint pricing scales with the fleet — predictable, but expensive when you manage thousands of low-value machines. Per-technician pricing is fixed regardless of device count — dramatically cheaper for small teams managing large fleets, and more expensive if you have many part-time technicians. A third axis hides inside both models: what counts as included. Remote access seats, third-party patching, network monitoring and reporting are each sold as add-ons by some vendors, so two quotes with the same headline rate can differ meaningfully once the estate is fully licensed.
How to choose an RMM
Model total cost at your projected size, verify the agents on the operating systems you actually run, and confirm what is included versus upsold — those three checks settle most shortlists before any demo does.
- Model the cost at your projected size, not today's — RMM pricing is the line item that grows fastest
- Verify macOS and Linux agent depth if you run them; many platforms are Windows-first in practice
- Check whether remote access and patching are included or upsold — and see how patch management works for what third-party coverage should include
- For MSPs: multi-tenancy, per-client reporting and role separation are non-negotiable
- Check the automation model — can non-scripters build useful automation, or does everything need PowerShell?
- Consider whether a separate RMM is the right shape at all, or whether you want it inside the platform that already holds tickets, assets and monitoring — the RMM vs MDM distinction matters here too
Infronest
Conclusion
Infronest includes RMM and endpoint management alongside server and network monitoring, IT assets, helpdesk, patch management and VAPT — in one tenant-isolated workspace. For MSPs, each client gets a genuinely isolated environment rather than a filtered view.

Frequently Asked Questions
- What is the best RMM tool for a small MSP?
- For small teams managing large fleets, Atera's per-technician pricing is often the most economical. NinjaOne is a strong all-round choice for mid-size MSPs, and ConnectWise Automate and Datto RMM suit larger operations that will invest in deep automation. The best choice usually comes down to pricing model and agent quality on your OS mix.
- How much do RMM tools cost?
- Most vendors quote rather than publish, so published prices vary — check each vendor directly. The structural choice matters more than the rate: per-endpoint pricing scales with your fleet, per-technician pricing (Atera's model) stays flat as devices grow, and add-ons such as remote access seats and third-party patching can change the real total significantly.
- What is the difference between RMM and MDM?
- RMM focuses on monitoring device health and delivering remote maintenance and support at scale. MDM focuses on enforcing configuration, security policy and compliance, with deeper mobile coverage. They overlap on patching, scripting and remote access — what is RMM covers the boundary in detail.
- Do internal IT teams need RMM, or is it only for MSPs?
- Internal teams benefit for the same reasons MSPs do: continuous monitoring, automated patching, remote support and inventory. The multi-tenancy features matter less, so an internal team can often choose on agent quality and cost alone.
- Which RMM tools have a free tier?
- Action1 offers a free tier for small estates, which is the most practical zero-cost way to get real patch management running. Most full RMM suites offer trials rather than free tiers, so budget-conscious teams should compare Action1's free coverage against a paid platform's breadth.
- Is per-endpoint or per-technician RMM pricing better?
- Per-technician pricing wins when few engineers manage many devices — the cost stays flat as the fleet grows. Per-endpoint pricing wins when device counts are modest or headcount is large and variable. Model both at the size you expect to be in two years, not the size you are today.
- Does an RMM replace a helpdesk or PSA?
- Not by itself. RMM is the technical layer; ticketing, SLAs, contracts and billing live in a helpdesk or PSA. Some platforms bundle both — Atera includes helpdesk features, and Infronest pairs RMM with a full helpdesk in the same workspace — but a pure RMM still needs a ticketing system beside it.
