MantisRMM alternative: pricing and feature comparison

MantisRMM is a cross-platform RMM with per-agent pricing and unlimited technicians. Nizlo is a Windows-first RMM with flat public plans and unlimited RMM endpoints. They are not equivalent products.

The honest short version

MantisRMM publishes the stronger fit for cross-platform patching, vulnerability context, unlimited technicians, and broader MSP security controls. At small fleets its $20 minimum also costs less than Nizlo. Nizlo’s narrower case begins when one technician manages a growing Windows-first fleet and flat endpoint pricing matters more than that breadth.

Paid pricing

MantisRMM: $2 per active agent per month, with a 10-agent minimum and quantities added in steps of 10. Unlimited technicians are included and billing is monthly with no annual lock-in.

Nizlo: $59/month Core or $79/month Scale with one technician and unlimited RMM endpoints. Additional technicians are $15/month each, with no annual software commitment required.

Trial

MantisRMM: No credit card and up to 10 devices. Current official pages conflict: the pricing and MSP pages say 15 days, while the homepage and platform page say 30 days. Confirm the active term at signup.

Nizlo: 14 days, no credit card, no automatic charge, and unlimited RMM endpoints in the Scale trial. The workspace opens immediately.

Endpoint platforms

MantisRMM: Native Windows, Linux, and macOS agents. Published system requirements cover current Windows and Server releases, systemd Linux on x86-64 and ARM64, and macOS 14+ on Intel and Apple silicon.

Nizlo: Windows and macOS agents are available. Nizlo remains Windows-first; Linux is a limited private preview without Linux patching or remote desktop.

Patching and vulnerabilities

MantisRMM: Windows Update and WinGet, Linux apt/dnf/zypper, macOS softwareupdate, plus installed-software correlation with NVD, EPSS, and CISA KEV.

Nizlo: Windows Update patching with approval, scheduling, reboot controls, and result evidence. Nizlo does not claim cross-platform patching, broad third-party app patching, or vulnerability-management parity.

Automation and remote

MantisRMM: PowerShell, Bash, and Python scripts; chained workflows; processes, services, and files. The product page specifically describes full remote desktop for Windows endpoints.

Nizlo: PowerShell-centered scripts, scheduled workflows, jobs, services, file workflows, and remote support for supported endpoints. Validate every required platform and action in the pilot.

MSP administration

MantisRMM: Company and site organization, per-client technician scopes, unlimited technicians, dedicated customer database/storage, and a tamper-evident audit log with webhook or SIEM streaming.

Nizlo: Customer and site organization, role-based technician access, monitoring, reporting, tickets, and retained evidence. Nizlo has a smaller ecosystem and does not claim feature parity with MantisRMM's published security and SIEM scope.

MantisRMM is the stronger fit when

Cross-platform depth or technician count leads

  • Linux and macOS patching are required now
  • WinGet application updates and vulnerability context matter
  • many technicians must be included without per-seat fees
  • per-client scopes, SIEM streaming, and published audit controls lead the decision

Nizlo may be worth testing when

A larger Windows-first fleet changes the economics

  • one technician manages enough endpoints for flat pricing to matter
  • the required workflow fits Nizlo without cross-platform patching or vulnerability parity
  • an immediate self-service workspace is preferable to reviewed activation
  • unlimited trial endpoints make a wider authorized pilot useful

Compare endpoint count and technician count together.

These subscription-only examples use one technician and MantisRMM’s published $2 active-agent rate. MantisRMM includes unlimited technicians; Nizlo adds $15 per additional technician. Neither table proves product parity or complete operating cost.

Run the same pilot in both products

Test 1Enroll the same authorized Windows endpoints and reconcile customer, site, hostname, user, serial, agent version, and duplicate identity.
Test 2Trigger identical offline, disk, service, and resource conditions; compare routing, persistence, recovery, noise, and technician effort.
Test 3Run the same Windows patch ring; compare approval, scheduling, reboot behavior, exceptions, reporting, and partial-failure evidence.
Test 4If third-party or cross-platform patching matters, prove the required applications and operating systems in MantisRMM and document the retained Nizlo-side tool.
Test 5Run an authorized script and remote session with the same role; compare review, consent, output, revocation, evidence, and platform boundaries.
Test 6Invite the real technician roles and verify customer scoping, least privilege, audit visibility, and offboarding in both products.
Test 7Price the current fleet and twelve-month growth using endpoint and technician counts plus every retained security, PSA, backup, and integration tool.
Test 8Export required records, remove agents, revoke technicians, stop schedules and integrations, and prove access no longer succeeds.
