The spec sheets make these two look close. They aren't, once you ask the only question that actually matters with a video doorbell: what does it do without a monthly fee? The Arlo is the cheaper box — roughly $80–130 against the Nest's $120–180 — but strip away the Arlo Secure subscription and it loses recorded video *and* the person/vehicle/package detection that justify buying a smart doorbell in the first place. The Nest runs its smart alerts on-device for free and includes a few hours of event history without paying anyone anything.
That's the real difference. Resolution, field of view, and app polish are all secondary to it, so settle the subscription question first and the rest of this gets easy.

Do the three-year math, not the checkout math
A doorbell is a five-plus-year purchase, and subscriptions compound. Arlo's lower sticker price evaporates after a year or so of Arlo Secure, and owners have been burned by renewal price hikes on top of that. The Nest flips the equation: more up front, but a genuinely useful free tier — smart alerts that distinguish people, packages, animals, and vehicles, plus that short window of event history. If a few hours of history covers your needs (it does for a lot of people: see the alert, check the clip, done), the Nest is the cheaper doorbell over any horizon longer than a few months.
One honest caveat: the Nest's free history is short. If you want days of recordings — say, to review a weekend away — you're into Nest Aware, and the "no subscription" advantage narrows. It never disappears, though, because Arlo without Secure isn't just limited, it's gutted.
Picture and ecosystem
The Arlo counters with a sharp 2K sensor and a square 180-degree view that shows a visitor head to toe and the porch floor in one frame. It's a genuinely nice image, and if crispness on faces at the door matters to you, Arlo has the edge. The Nest answers the same problem differently: a tall 3:4 aspect ratio that catches packages on the ground without needing the full fisheye treatment.
Ecosystem is the other honest Arlo win. It works with both Alexa and Google Home. The Nest is best inside Google Home, full stop — that's where its alerts, history, and hub displays all live. Both units install wired or on battery, so wiring won't decide this for you.
Who should skip which
Skip the Nest if you're an Alexa household. You'd be paying a premium for a doorbell built around an ecosystem you don't use — it's also pricier than a base Ring, which is the more natural Alexa companion anyway.
Skip the Arlo if you know you won't pay monthly. Without Secure it's an expensive live-view chime. Also think twice if your door sees heavy traffic or hard winters — battery life is mediocre in busy or cold locations, and a doorbell you're constantly recharging is a doorbell you eventually stop trusting.
Bottom line
The Nest rates higher (4.5 vs 4.0) and that gap matches how the two are built: Nest gives you the important features free and charges for extras; Arlo charges for the important features. Buy the Nest if you're in Google Home or simply refuse a subscription — it's the safer money for most people. Buy the Arlo if you want 2K detail and the 180-degree view, need Alexa and Google support in one device, and have already made peace with paying for Arlo Secure. Just make that peace before checkout, not after.
