Ring and SimpliSafe are the two names most people weigh when they want a DIY security system without a contract. Both are genuinely good: both install yourself, both let you cancel monitoring any time, and both have loyal owners. This comparison is here to be honest about the differences that actually decide it — and to be upfront about one thing most comparison pages hide: we recommend and link the Ring Alarm because it's the system we can point you to buy through our Amazon program. SimpliSafe isn't sold on Amazon, so there's no buy button for it here. We'll still give you the straight comparison so you can decide.
Monitoring cost: Ring is cheaper
This is the clearest split. Both companies are contract-free, but Ring's 24/7 professional monitoring plan costs less per month than SimpliSafe's, at every tier. Over the years you'll own the system, that monthly gap compounds into real money. If your plan is to pay a monitoring center to watch the house around the clock, Ring is simply the cheaper way to do it — the numbers are in the table below, and you should confirm both brands' current rates before you buy, since plan pricing moves.
Self-monitoring: Ring is free
Ring lets you self-monitor at no cost forever — the alarm sirens and pushes an alert to your phone with no plan. That's a real advantage for anyone comfortable responding to their own alerts. SimpliSafe's remote and app features center on its paid plans, so if no-monthly-fee operation matters to you, confirm exactly what SimpliSafe's no-plan mode includes on its own site before deciding. For the full argument on when free self-monitoring is enough, see the DIY vs monitored guide.
Hardware and ecosystem: closer than you'd think
On the fundamentals the two are similar. Both use adhesive door/window and motion sensors, a base station and a keypad; both are true DIY with no drilling into wiring. Neither works with Apple HomeKit, so an iPhone-first household that wants the alarm in the Home app should skip both and look at the abode iota instead. Ring leans into the Alexa world and a very large accessory catalog; SimpliSafe works with Alexa and Google Home. For most buyers the ecosystem difference is a wash — the cost and where you can buy it are what move the decision.
Why we point you to Ring
To be plain about it: our buy links go through Amazon, and Ring is on Amazon while SimpliSafe isn't. That's part of why Ring is our pick here — but it's not the only reason, and we wouldn't recommend it if the value weren't real. Ring genuinely costs less to monitor and lets you self-monitor free, which is why it also leads our main systems roundup. If you'd rather buy SimpliSafe after reading this, that's a perfectly reasonable choice — you'd just do it on SimpliSafe's own site.
Buy Ring if...
You want the lower monthly cost, you like the idea of self-monitoring free to start, your home uses Alexa, or you simply want a proven kit you can order today with a live price. That covers most buyers, which is why Ring is our recommendation between the two. The full write-up is in the Ring Alarm review.
Consider SimpliSafe if...
You specifically prefer SimpliSafe's hardware or its monitoring experience and don't mind paying a bit more each month. It's a legitimate system — just one you'd buy direct rather than through us. And if neither quite fits because you want Apple HomeKit or the cheapest all-in-one, weigh both against the field in the DIY systems roundup.
