How TacticalRMM Went From Side Project to the RMM 5,000+ MSPs Run in Production

In 2020, a frustrated MSP technician named Wes Moskal started building what would become one of the most disruptive forces in the remote monitoring and management space. TacticalRMM wasn't born in a venture-backed startup accelerator or enterprise software lab. It emerged from a simple frustration: commercial RMM tools were expensive, inflexible, and packed with features most MSPs never used.

Fast forward to 2025, and TacticalRMM has fundamentally changed the conversation around MSP tooling. It's forced commercial vendors to justify pricing that often exceeds $3-5 per endpoint monthly. TacticalRMM proved that an open-source RMM can compete with — and in some workflows outperform — tools costing $3–5 per endpoint monthly. And it's created a community-driven support model that rivals-and in some cases surpasses-the responsiveness of paid enterprise support.

This isn't a sales pitch for TacticalRMM. It's an honest examination of how a side project became a movement, why OpenFrame chose it as the foundation for their unified open-source MSP platform, and where it still has room to grow. If you're an MSP owner tired of escalating licensing costs or an IT director seeking more control over your tooling, this story matters.

The Origin Story: Born From Frustration, Built for MSPs

Wes Moskal didn't set out to disrupt an industry. He was working at an MSP, dealing with the same pain points that plague thousands of service providers: clunky interfaces, vendor lock-in, and pricing models that punished growth. Every new client meant higher RMM costs, and the features his team actually used represented maybe 20% of what they were paying for.

The initial commit to the TacticalRMM GitHub repository happened in June 2020. Built on Python and Django for the backend, with a Vue.js frontend, the architecture was deliberately chosen for maintainability and community contribution. Unlike commercial tools built on proprietary stacks, TacticalRMM's tech stack meant any competent developer could understand, modify, and improve the codebase.

What made TacticalRMM different from day one wasn't just the open-source license. The core TacticalRMM features reflect what MSPs actually use daily: agent deployment and management, script execution (PowerShell, batch, Python), Windows patch management, automated monitoring checks with alerting, and remote access via MeshCentral integration. No bloat. No enterprise features designed for Fortune 500 companies.

The project gained traction quickly in MSP communities on Reddit and Discord. Technicians who had been quietly frustrated with commercial tools suddenly had an alternative they could inspect, modify, and deploy without per-endpoint fees eating into margins. By late 2020, early adopters were running TacticalRMM in production environments, and the feedback loop between users and developers was remarkably fast.

Technical Decisions That Made the Difference

TacticalRMM's technical architecture reflects lessons learned from commercial RMM limitations. The decision to use PostgreSQL for the database, Redis for caching and message queuing, and Nginx for the web server created a stack that's both performant and familiar to systems administrators.

The agent architecture deserves special attention. Written in Go, the TacticalRMM agent is lightweight, cross-platform, and communicates with the server via websockets for real-time updates. This design choice means agents maintain persistent connections, enabling instant command execution without the polling delays that plague some commercial solutions. The agent's resource footprint is minimal-typically under 50MB of RAM-making it suitable even for older endpoints.

Self-hosting was another critical decision. While it adds deployment complexity, self-hosting gives MSPs complete control over their data, eliminates recurring SaaS fees, and allows customization that would be impossible with cloud-only solutions. For MSPs serving clients in regulated industries or those with strict data sovereignty requirements, this control is non-negotiable.

The integration architecture is equally important. TacticalRMM's API-first design means it plays well with other tools. Native integrations with MeshCentral for remote access, Tactical's own scripting library, and webhook support for connecting to PSA tools create an ecosystem rather than a walled garden. This extensibility is precisely what frustrated MSPs were seeking.

One practical consideration: TacticalRMM code signing. The agent executables need to be signed for deployment in enterprise environments where unsigned binaries get blocked by endpoint protection. TacticalRMM offers signed agents through their sponsors program — a paid tier. For MSPs deploying to clients with strict security policies, this is worth factoring into the cost comparison.

The Community Support Model: Discord Over Support Tickets

Traditional RMM vendors offer tiered support: basic email support, premium phone support, and enterprise dedicated account managers. TacticalRMM flipped this model entirely. The primary support channel is a Discord server with thousands of active members, including core developers, experienced users, and newcomers.

This community-driven approach has surprising advantages. Response times in the Discord often beat commercial support tickets. When an MSP encounters an issue at 2 AM, there's usually someone online who has faced the same problem. The searchable history of Discord channels creates an organic knowledge base that's often more practical than formal documentation.

The community also drives feature development. Users submit feature requests via GitHub issues, discuss implementation approaches, and sometimes contribute pull requests themselves. This transparent development process means features get prioritized based on actual MSP needs rather than vendor roadmaps designed to justify price increases.

However, this model has limitations that need honest acknowledgment. Community support requires active participation. If you post a question and expect a guaranteed response within four hours like an enterprise SLA promises, you'll be disappointed. For MSPs without in-house technical expertise or those uncomfortable with community-based support, this represents a genuine barrier to adoption. The trade-off between cost savings and support predictability is real.

Where TacticalRMM Still Falls Short

Balanced analysis requires acknowledging gaps. TacticalRMM's documentation, while improving, still lags behind commercial vendors with dedicated technical writing teams. New users often find themselves piecing together information from Discord conversations, GitHub issues, and community blog posts. The learning curve is steeper than clicking through a SaaS onboarding wizard.

The self-hosted deployment model, while offering control, also means MSPs are responsible for infrastructure, updates, security hardening, and backup strategies. Commercial RMM vendors handle this infrastructure burden, and for small MSPs without dedicated IT staff, this operational overhead is significant. You need to understand Linux server administration, SSL certificate management, and database maintenance.

Reporting and analytics capabilities are another area where TacticalRMM trails commercial solutions. While it handles the core monitoring and management tasks excellently, generating client-facing reports or executive dashboards requires additional tooling or custom development. MSPs accustomed to built-in reporting wizards will notice this gap.

Mobile access is limited compared to commercial RMM apps. While the web interface is responsive, there's no dedicated mobile app with offline capabilities. For technicians who need to respond to alerts while away from their desks, this represents a workflow compromise.

These limitations aren't dealbreakers for many MSPs, but they're important considerations. TacticalRMM works best for technically capable teams who value control and cost savings over turnkey convenience. It's not the right fit for every MSP, and that's okay.

Why OpenFrame Chose TacticalRMM as Their Foundation

When OpenFrame set out to build a unified open-source platform for MSPs, the RMM component was the most critical decision. They evaluated multiple options, including building from scratch, but TacticalRMM's battle-tested codebase and active community made it the clear choice.

OpenFrame's selection process focused on three criteria: proven production reliability, active development community, and architectural compatibility with their broader platform vision. TacticalRMM scored highly on all three. Thousands of MSPs were already running it in production, proving it could handle real-world workloads. The GitHub repository showed consistent commits and responsive maintainers. And the API-first architecture meant integration with OpenFrame's other components would be straightforward.

The decision also reflected OpenFrame's philosophy about open-source MSP tooling. Rather than fragmenting the ecosystem with yet another RMM project, they chose to build on and contribute back to an existing community. This approach strengthens TacticalRMM while allowing OpenFrame to focus on the integration layer, unified interface, and additional tooling that MSPs need.

OpenFrame's involvement signals something important about TacticalRMM's maturity. When a company building a commercial platform chooses your open-source project as a foundation, it's a strong validation signal. It means the code quality, architecture, and community health passed scrutiny from engineers betting their business on the technology.

Market Impact: Forcing Vendors to Justify Their Pricing

When commercial RMM providers announce price increases, MSPs now have a credible alternative to point to. The question is no longer "Can we afford this increase?" but "What are we getting for $4 per endpoint that TacticalRMM doesn't provide for free?"

Some commercial vendors have responded by emphasizing their support infrastructure, compliance certifications, and enterprise features. Others have adjusted pricing models or improved their value propositions. A few have dismissed TacticalRMM as unsuitable for serious businesses, though this argument becomes harder to sustain as more MSPs successfully deploy it.

The competitive pressure extends beyond pricing. Commercial vendors are now more responsive to feature requests and more transparent about roadmaps because they know frustrated customers have alternatives.

What does TacticalRMM actually cost?

The core platform is free and open source — no per-endpoint fees, no license tiers. But TacticalRMM pricing isn't truly zero when you factor in infrastructure costs (a Linux VPS runs $10–50/month depending on endpoint count), the code-signed agent sponsorship ($55/month as of 2026), and the labor hours for setup and maintenance. For a 500-endpoint MSP, realistic all-in costs run roughly $50–100/month compared to $1,500–2,500/month for commercial alternatives like ConnectWise or Datto. That's the math that's reshaping vendor conversations.

Migration Stories: Implementation Reality Check

MSPs migrating from commercial RMM tools to TacticalRMM report similar patterns. The initial deployment takes longer than expected-typically 2-4 weeks for proper setup, testing, and agent rollout. The learning curve is real, especially for teams accustomed to vendor-managed infrastructure.

However, once deployed, most report high satisfaction with day-to-day operations. The interface is fast and responsive. Script execution is reliable. Alerting works as expected. The cost savings become immediately apparent when the next commercial RMM invoice doesn't arrive.

Common migration challenges include script conversion from proprietary formats, recreating custom monitoring checks, and training staff on the new interface. MSPs who document their existing workflows before migration fare better than those who try to wing it.

The Discord community plays a crucial role during migrations. Experienced users share deployment scripts, troubleshooting tips, and configuration best practices. Several MSPs have published detailed migration guides as blog posts, creating a knowledge base that smooths the path for newcomers.

Not every migration succeeds. Some MSPs discover they relied more heavily on commercial vendor features than they realized. Others find the self-hosted operational burden exceeds their capacity. The key is honest assessment of technical capabilities and support requirements before committing to migration.

The Future: What This Movement Signals for MSP Software

TacticalRMM represents more than one successful open-source project. It's evidence that the MSP software market is ready for disruption. For years, MSPs have been price-takers, accepting whatever licensing models vendors imposed. That dynamic is shifting.

The success of TacticalRMM has inspired similar projects in adjacent categories. Open-source PSA tools, documentation platforms, and security tooling are emerging with similar community-driven models. The vision of a complete open-source MSP stack is no longer theoretical-it's being built in real-time.

OpenFrame's unified platform approach suggests the next evolution: integrated open-source ecosystems that rival commercial suites in functionality while maintaining the transparency, control, and cost advantages that attracted MSPs to TacticalRMM initially.

Commercial vendors aren't going away, nor should they. They serve important market segments and drive innovation through R&D investment. But the market is becoming more diverse, with room for both commercial solutions and open-source alternatives. MSPs benefit from having genuine choices.

The broader signal is about power dynamics in B2B software. When users have technical capability and community support, they can build alternatives to expensive commercial tools. Vendors who provide genuine value will thrive. Those who relied on lock-in and inertia will face increasing pressure.

For MSP decision-makers, TacticalRMM's trajectory offers a clear lesson: evaluate tools based on actual value delivered, not just vendor marketing. Whether you choose commercial or open-source solutions, demand transparency, fair pricing, and respect for your business needs. The tools exist to serve your MSP, not the other way around.

Conclusion

TacticalRMM's journey from side project to industry disruptor proves that open-source alternatives can compete with commercial vendors when built by people who understand real-world pain points. It's not perfect-the documentation gaps, self-hosting complexity, and community support model won't work for every MSP. But for technically capable teams tired of escalating licensing costs and vendor lock-in, it represents a credible alternative that's been battle-tested in thousands of production environments.

OpenFrame's decision to build on TacticalRMM validates what early adopters already knew: this isn't an experiment or hobby project. It's a mature, production-ready platform that's changing the economics of MSP tooling. Whether you ultimately choose TacticalRMM, stick with your commercial vendor, or explore other alternatives, the competitive pressure it creates benefits the entire MSP community.

The future of MSP software will be more diverse, more transparent, and more respectful of the businesses it serves. TacticalRMM helped make that future possible.
