Open Source RMM: The 2026 Landscape
An honest comparison of the four leading open source RMM platforms — MeshCentral, TacticalRMM, NetLock RMM, and Breeze — covering feature depth, self-hosting realities, and when open source is the right fit.
TL;DR
If you only need self-hosted remote access and file transfer, MeshCentral is the mature, battle-tested choice. If you need script-based monitoring and Windows patching on top of remote access, TacticalRMM extends MeshCentral with a community-driven RMM layer. If you need EU data sovereignty, whitelabel, and a free tier up to 25 devices, NetLock RMM is the European option. If you need a full commercial-grade platform — monitoring, patching, compliance automation, and optional AI — without per-device fees, Breeze covers the full scope.

Why open source matters for RMM specifically
The arguments for open source RMM are not the same as for open source databases or web servers. RMM has unique characteristics that make the open source case particularly strong.
Transparency and auditability
Your RMM agent runs as a system service with administrative privileges on every managed device. It can execute commands, install software, and read files. With a closed-source RMM, you are trusting the vendor's claims about what that agent does. With open source, you can read the code, audit what data it collects, and build the agent from source to verify the binary matches. For a component with privileged access to your entire fleet, that is a meaningful reduction in supply-chain risk.
No vendor lock-in
Every commercial RMM accumulates lock-in over time — monitoring configurations, automation scripts, client hierarchies, and historical data all live in the vendor's system. Switching is a multi-week-to-multi-month project, which is why vendor price increases after the initial contract are common. Open source reduces this in two ways: you own the data (in a database schema you can query), and you can fork the platform if the project stalls or takes a direction you disagree with.
Cost structure
No per-device fees. A $50–100/month VPS typically handles 500–1,000 endpoints, compared to $1,500–2,500/month in commercial per-device fees at the same scale. The hidden cost is operational — you are responsible for hosting, updates, and backups — but for technically capable teams, that cost is dramatically lower than the commercial alternative. The math is especially tight for MSPs running 50–500 endpoints, where the RMM bill is often a material factor in whether the business works.
Compliance positioning
A growing number of compliance frameworks and client contracts include requirements around software supply-chain transparency. Being able to point to auditable source code for your primary management tool is a differentiator in compliance-sensitive industries. It is not sufficient on its own — you still need proper deployment and operational practices — but it eliminates one category of audit question entirely.
The open source RMM landscape in depth
MeshCentral
Apache-2.0MeshCentral is a mature, actively developed open source remote management platform originally built at Intel and now maintained by Ylian Saint-Hilaire. It has the largest user base and the longest track record in the open source RMM space.
What it does well
Browser-based remote desktop with full keyboard/mouse control, file transfer, terminal access, and multi-monitor support. The implementation is fast, responsive, and cross-platform across Windows, macOS, Linux, and FreeBSD. Multi-user support with group-based permissions works well for team environments. Intel AMT integration enables hardware-level management for supported devices.
What it does not do
MeshCentral is not a full RMM. No monitoring (CPU, memory, disk thresholds), no alerting, no patch management, no software inventory, no compliance tooling, no automation workflows, no reporting, and no configuration management. It is a remote access and command execution platform — if you need to restart a service or troubleshoot remotely, it handles that; if you need to know the service stopped in the first place, you need something else.
Architecture
Node.js server, MeshAgent client (C-based, cross-platform), NeDB or MongoDB storage. Runs on minimal hardware — a single 1–2 GB RAM VPS handles hundreds of agents. Installation is straightforward with the included setup scripts.
Who should use it
IT teams that primarily need remote access without monitoring or automation. Shops currently using TeamViewer or AnyDesk who want a self-hosted, no-per-device-fee alternative. Teams building a management stack from components, with MeshCentral handling the remote access layer.
TacticalRMM
Tactical RMM LicenseTacticalRMM is the most well-known community-driven open source RMM. It was built on top of MeshCentral (for remote access) and has grown into a capable platform with monitoring, scripting, automation, and basic patch management.
What it does well
Scripting is TacticalRMM's strongest feature — the script engine supports PowerShell, Bash, Python, and batch files, with a script library, variable injection, and output capture. The community has built a large shared script library. Monitoring is script-based: you define checks as scripts, TacticalRMM runs them on schedule and alerts on exit codes or output. Automated tasks, scheduled scripts, and basic Windows patch management round out the platform. The Discord community is active and knowledge-sharing is good.
What it does not do
No SNMP or network device monitoring, no native compliance tooling, no backup verification, no disk encryption management, no advanced reporting, no CIS Benchmark assessment, no vulnerability correlation (CVE scanning against software inventory), and no AI-driven automation. The monitoring is script-based rather than agent-native, which means you are writing and maintaining the checks yourself rather than getting structured data collection built into the agent.
Architecture
Django backend, Vue.js frontend, PostgreSQL database, MeshCentral for remote access, Go agent for Windows and Linux. Docker-based deployment. The multi-component stack (Django + PostgreSQL + MeshCentral + Redis + Celery + Nginx) means the hosting environment needs reasonable resources — 4 GB RAM minimum, 8 GB recommended for production.
Who should use it
MSPs comfortable with Linux administration who want a capable open source RMM with strong scripting. Teams that prioritize script-based automation and are willing to write and maintain their monitoring checks. Shops currently using MeshCentral that want to add monitoring and automation without switching to a commercial platform.
NetLock RMM
AGPL-3.0NetLock RMM is an independently developed German open source RMM, released under AGPL-3.0 with active development since late 2024. The project emphasizes data sovereignty, whitelabel support, and a genuinely free Community Edition up to 25 devices.
What it does well
Multi-tenancy with granular role-based permissions. Remote tools — browser-based shell, file browser, and screen control — work across Windows, macOS, and Linux on both x64 and ARM64. Security posture features include antivirus management, firewall monitoring, and security baseline enforcement. Automation is handled through jobs and sensors for scheduled scripts and policy-driven monitoring. Policy management supports auto-assignment. Whitelabel customization is built in from the Community Edition. SSO and MFA are included. Notifications ship to email, Microsoft Teams, Telegram, and webhooks out of the box.
What it does not do
No CIS Benchmark assessment or framework-level compliance automation. No CVE correlation against software inventory. No SNMP or network device monitoring. No backup verification. No AI capabilities. Windows patch management is baseline-enforcement oriented rather than a full lifecycle patch workflow. The Community Edition device cap is 25; larger deployments need the paid Professional tier (€55/month at time of writing) or cloud-hosted option.
Architecture
C# / .NET 8 server with ASP.NET Core on Kestrel, Blazor Server with MudBlazor for the web console, MySQL database, SignalR over WebSockets for real-time transport, cross-platform agents (Windows, Linux, macOS; x64 + ARM64). Docker and Kubernetes deployment are supported. Can run fully air-gapped for environments with strict data sovereignty requirements.
Who should use it
EU teams prioritizing data sovereignty and German-built tooling. Small MSPs under 25 devices looking for a free and capable self-hosted RMM. Shops that need whitelabel and SSO out of the box without buying an enterprise tier. Teams comfortable operating a .NET + MySQL stack. Anyone evaluating open source RMM options who wants a European alternative to US-hosted projects.
Breeze
AGPL-3.0Breeze is a full-platform open source RMM built from scratch with an AI-native architecture. Full disclosure: we built it.
What it does
44 modules covering the full RMM scope: device monitoring and management, patch management with lifecycle workflows, remote access via native WebRTC, event/schedule/webhook/manual automation, SNMP monitoring, network intelligence with auto-discovery, software inventory with NVD-correlated CVE scanning, CIS Benchmark assessment (450+ checks across Windows, macOS, and Linux), compliance automation covering 13 of 18 CIS Controls, backup verification with test restores, browser extension risk classification, DNS security integration, hierarchical configuration policies, maintenance windows, reporting and analytics, and an optional AI brain layer that provides correlation, triage, and risk-classified autonomous action.
The architecture is four layers — Go agent, PostgreSQL storage, Hono/TypeScript API, Claude Agent SDK brain — designed so the RMM is fully functional without the AI layer. You can run Breeze as a traditional RMM with no AI involvement. The brain multiplies what a technician can do but is not required for core function.
What it does not do as well as established platforms — yet
The PSA integration ecosystem is narrower than Datto or ConnectWise. The community is smaller and newer than TacticalRMM's. Some vendor-specific integrations that mature platforms have accumulated over years are still in development.
Architecture
Go agent (cross-platform: Windows, macOS, Linux), PostgreSQL, Hono/TypeScript API, optional AI brain via Claude Agent SDK. Self-hosted or managed cloud (beta — US and EU). Single-database architecture simplifies backup and recovery compared to multi-database setups. Every UI action is available via API, so integrations and automation have full platform access.
Who should use it
MSPs that want a complete RMM platform without per-device fees. Teams that need compliance automation and do not want to build it from scripts. Organizations that want AI-driven operations but need the underlying platform to work without AI as a fallback. Anyone who wants the transparency and control of open source with the feature depth of a commercial platform.
Self-hosting considerations
Self-hosting an RMM is not the same as self-hosting a blog. The RMM is a critical infrastructure component — if it goes down, you lose visibility into and management of your entire fleet.
Infrastructure
MeshCentral: 1–2 GB RAM VPS handles hundreds of agents. TacticalRMM: 4–8 GB RAM recommended for production with 200+ agents (multi-component stack). NetLock RMM: 2–4 GB RAM for the Community Edition (25 devices) on a .NET + MySQL stack; Docker and Kubernetes supported. Breeze: comparable to TacticalRMM with a simpler single-PostgreSQL architecture.
Operational overhead
The real cost of self-hosting is not the server bill — it is operational work. Updates, backups, TLS certificate management, database maintenance, and security patching of the host OS and dependencies. Budget time accordingly.
Security responsibility
When you self-host, you own platform security: firewall, TLS, database access, OS hardening, backup encryption, access logging. If your RMM server is compromised, the attacker has administrative access to every managed endpoint. RMM platforms have been targeted in supply-chain attacks precisely because of this leverage.
When open source RMM is the right choice
Open source is not universally better or worse than commercial. The decision depends on your specific situation.
Open source makes sense when
- • Per-device pricing is a material constraint on your margin
- • You have the technical capability to self-host and maintain infrastructure
- • Your clients have data-sovereignty requirements that eliminate cloud-only options
- • You want to audit the software that has administrative access to your fleet
- • You want to avoid vendor lock-in and maintain control of your data
- • You need compliance capabilities but cannot afford enterprise commercial platforms
Commercial makes sense when
- • You do not have the technical depth or desire to manage hosting
- • You need vendor-backed SLAs for uptime and support
- • Your PSA integration requirements are specific to a particular vendor ecosystem
- • Per-device cost is not a material factor in your economics
- • You value phone support over community-based support
The hybrid approach: several open source projects, including Breeze, offer both self-hosted and managed cloud options. You can start cloud-hosted and migrate to self-hosted later, or run a hybrid — some clients through the cloud instance, compliance-sensitive clients through a self-hosted instance.
Frequently asked questions
Answers to the questions people ask most often when evaluating open source RMM.
What is an open source RMM?
An open source RMM is a remote monitoring and management platform whose source code is publicly available under a license that permits inspection, modification, and self-hosting. It gives IT teams and MSPs the same core capabilities as commercial RMM — remote access, monitoring, patching, and automation — without per-device fees or vendor lock-in, and with the ability to audit exactly what the agent running on every managed device is doing.
What are the best open source RMM tools in 2026?
The leading open source RMM projects in 2026 are MeshCentral (mature remote management and remote desktop), TacticalRMM (community-driven RMM with strong scripting, built on top of MeshCentral), NetLock RMM (German-built AGPL platform with whitelabel and a free Community Edition up to 25 devices), and Breeze (a full-platform RMM with 44 modules, compliance automation, and an optional AI brain). Each targets a different level of scope and geography.
Is Breeze really free and open source?
Yes. Breeze is released under the AGPL-3.0 license. The complete source code is available on GitHub, and you can self-host the entire platform with no per-device fees, no user caps, and no feature gating. A managed cloud option is also available in beta (US and EU) for teams that prefer not to run the infrastructure themselves.
Can I self-host an open source RMM for free?
Yes. All four leading open source RMMs — MeshCentral, TacticalRMM, NetLock RMM, and Breeze — can be self-hosted at no licensing cost (NetLock's Community Edition caps at 25 devices on the free tier). Your only expenses are infrastructure: a VPS with 1–8 GB of RAM (depending on the platform) typically costs $10–100 per month and handles 200–1,000 endpoints. That is usually an order of magnitude cheaper than commercial RMM per-device pricing at comparable scale.
What's the difference between MeshCentral, TacticalRMM, and NetLock RMM?
MeshCentral is a remote management and remote desktop platform — excellent remote control, no monitoring or patching. TacticalRMM is built on top of MeshCentral and adds script-based monitoring, alerting, and Windows patch management. NetLock RMM is an independently developed German AGPL-3.0 project with multi-tenancy, security baseline management, whitelabel, and a free Community Edition up to 25 devices. If you only need remote access, MeshCentral fits. If you need script-heavy monitoring, TacticalRMM. If you need EU data sovereignty and whitelabel, NetLock.
Is open source RMM safe for MSPs and compliance-sensitive environments?
Yes, and auditability is often a compliance advantage over closed-source alternatives. Because you can inspect and build the agent from source, you can verify exactly what it does on managed endpoints — a meaningful reduction in supply-chain risk. The security responsibility shifts to you: you own host hardening, TLS, backups, and access control. With standard operational discipline, open source RMM meets the security requirements of HIPAA, SOC 2, and CIS Controls engagements.
What are the hardware requirements to self-host an open source RMM?
MeshCentral runs comfortably on a 1–2 GB RAM VPS and handles hundreds of agents. TacticalRMM recommends 4–8 GB RAM due to its Django + PostgreSQL + Redis + Celery + MeshCentral stack. NetLock RMM runs on a .NET + MySQL stack and needs roughly 2–4 GB RAM for the Community Edition at 25 devices. Breeze runs on comparable resources to TacticalRMM with a simpler single-PostgreSQL architecture. For production workloads of 200–500 endpoints, budget $50–100 per month for a properly sized VPS.
When should I choose commercial RMM over open source?
Commercial RMM makes sense when you lack the technical depth or desire to manage hosting infrastructure, when you need vendor-backed SLAs for uptime and support, when your PSA integration requirements are specific to a particular vendor ecosystem, or when per-device cost is not a material factor in your business economics. If any of those apply, the operational simplicity of a managed commercial platform can outweigh the higher cost.
What is NetLock RMM and is it free?
NetLock RMM is an open source (AGPL-3.0) remote monitoring and management platform built by a German developer, with active development and a public GitHub repository. The Community Edition is free and self-hosted with a 25-device limit, covering the full core platform — multi-tenancy, remote shell and screen control, antivirus and firewall monitoring, security baseline enforcement, jobs and sensors, and whitelabel support. The paid Professional tier (€55/month at time of writing) lifts the device limit and adds SLA support, and a cloud-hosted option is also available.
Deploy a full open source RMM platform for free
Breeze is the only open source project that covers the full commercial RMM scope — 44 modules, compliance automation, and an optional AI brain. Self-host with no per-device fees, or start with the managed cloud beta.
