Free RMM comes in two shapes that have almost nothing in common. One is a commercial product with a free tier, capped at a device count, which is a trial with no time limit. The other is open source, which is free of licence fees and expensive in the thing MSPs have least of, which is engineering time. Both are real options and they fail in opposite directions, so the useful question is not whether an RMM is free but what it is free instead of.
What a commercial free tier actually covers
Level publishes the clearest example in this record: the first ten devices are free, and paid pricing is $2 per device per month for every device on the account after that. The published step is unusually honest, ten devices free, eleven devices $22 a month, fifty devices $100 a month, which confirms the flat rate applies to your whole count once you pass ten rather than only to the devices above it. Ten devices is under one small client, so as a business plan it is nothing and as a proving ground it is excellent. Action1 is the vendor most associated with a free tier in the patching half of this market, and its pricing page answers a Cloudflare block to every reader available here, so this record carries no figure for it rather than repeating one from elsewhere.
Where a free tier stops being free, and how fast
The two structures to tell apart are the cliff and the ramp. A ramp charges only for devices above the free allowance, so growth costs proportionally. A cliff applies the paid rate to your entire count the moment you cross, so the eleventh device costs $22 rather than $2. Level publishes a cliff and says so plainly, which is the point: you can plan for it. A vendor that does not publish the step is the one to ask, because the cliff is invisible until the invoice. Either way the practical advice is the same. Deploy free against real machines on a real network, because how an agent behaves on a bad connection and how long the console takes to do a routine job are the things that decide whether an RMM works for your team, and they appear on nobody's pricing page.
What open source costs instead of money
Open source RMM removes the licence and adds a server you own, patches you apply, a database you back up, and an upgrade path you test. For a team with a spare engineer and strong opinions that is a genuine trade. For an MSP whose engineers are billable it is usually the most expensive option in the building, because the hours go somewhere and they come out of margin rather than out of a budget line where anyone can see them. The other cost is the one that arrives at three in the morning. A commercial vendor has an on-call team when the console is down; a self-hosted deployment has you. Price that honestly against $2 a device before choosing, because the licence saving on a 500-device fleet is a thousand dollars a month and one bad night can cost more.
Questions people ask about free rmm
Is there a genuinely free RMM?
Level publishes the first ten devices free, then $2 per device per month across the whole count. Ten devices is under one small client, so treat it as an unlimited-time trial rather than a plan.
What happens when I exceed a free tier?
It depends whether the vendor charges only for devices above the allowance or applies the paid rate to your whole count. Level publishes the second structure plainly: ten free, eleven devices $22 a month.
Is open source RMM cheaper?
It removes the licence and adds a server you patch, a database you back up and an upgrade path you test. For a team whose engineers are billable that is usually the more expensive option once the hours are counted.
What should I do with a free tier?
Run it against real machines on real networks. How the agent behaves on a bad connection and how long a routine job takes in the console are what decide the choice, and neither is on a pricing page.
