What TP-Link itself says about the two brands
Most comparisons of these brands are written as though TP-Link had not published anything on the subject. It has. The relevant page is a support FAQ about linking Kasa devices to the Tapo app, and it is unusually direct.
It opens with the answer: “Tapo and Kasa are both TP-Link smart home brands, and most Kasa devices can be managed directly from the Tapo app without any reconfiguration.” The exceptions it names are two: the Kasa KE100 and KE110 radiator thermostats. The linking process is a one-time authorization from the Tapo app — Me > Link Tapo with Kasa — and both apps have to be signed in to the same TP-Link ID, which is the single most common reason it fails for people.
What carries across is more than you would expect: devices, groups, Kasa Smart Actions, scenes, timers, away mode and schedules. So a household that has spent two years building Kasa automations is not starting again.
The four things that do not carry across
This is the section the brand pages skip, and it is the only part of the merge that costs you something.
1. Subscriptions are separate. TP-Link states that “Kasa Care and Tapo Care subscriptions are independent services,” and that a remaining Kasa Care subscription cannot be transferred. If you are paying for Kasa Care, that money does not follow you.
2. Your old cloud clips do not come with you. The page is blunt: “Kasa history cloud videos cannot be viewed in the Tapo App.” TP-Link’s own advice is to keep the Kasa app installed to watch historical footage, or download and export the clips locally before you move on. If you have footage you care about — an incident, an insurance claim — export it first.
3. Rooms do not survive the move. Linked Kasa devices “appear in the All Devices tab” and have to be assigned to rooms by hand. On a four-device house that is two minutes. On a thirty-device house it is an evening.
4. The move is one-directional. TP-Link documents Kasa devices being managed from the Tapo app, not the reverse — its FAQ describes linking as authorizing your Kasa account from inside Tapo. If you want one app, Tapo is the one you keep. And if you have a Kasa camera on Kasa Care, TP-Link’s advice is to cancel auto-renewal first and only subscribe to Tapo Care once the existing plan expires, because the two bills do not offset. If you are buying a video doorbell into this setup, buy it from the brand whose app you intend to live in.
Worth noting on the positive side: TP-Link’s own comparison table for a Kasa camera without Kasa Care already includes live view, instant notifications, two-way audio, activity zones, local storage, motion detection and person detection. Those are the features most buyers assume are behind the paywall, and on TP-Link’s own accounting they are not — the plan buys cloud clip history, rich notifications with snapshots and the summary features. That is consistent with how we rank this whole category on our no-subscription camera page.
Where Tapo clearly wins: Matter on the plugs
If you want one concrete, checkable reason to pick Tapo over Kasa on the hardware, it is this. TP-Link’s product page for the Tapo P110M carries the Matter Certified badge and lists its third-party platforms as Matter-Certified, Apple Home, Alexa, Google Assistant and Samsung SmartThings. TP-Link’s page for the Kasa EP25 claims no Matter certification anywhere — it lists voice control through “Siri, Alexa, Google Assistant, or Samsung SmartThings,” which is real Apple Home support, but it is TP-Link’s own integration rather than the standard.
Why that matters in practice: Matter certification means the plug can be commissioned into a household ecosystem by scanning a code, and it means the plug keeps working locally if the internet drops. TP-Link’s own Matter copy on the Kasa outdoor plug makes the point for us — “even without an internet connection, Matter devices seamlessly operate within your local network.” Our guide to Matter covers what the standard does and does not deliver in more detail.
The two plugs are otherwise close to identical, which is what makes the comparison clean. Both are 2.4 GHz-only 802.11b/g/n. Both are rated 15 A with a 1.8 kW resistive ceiling and a 1/6 HP motor limit. Both have the same 66 x 38 x 40 mm body. Both meter power in real time and historically. The honest cons are shared too: a 2.4 GHz-only radio is a nuisance on a combined-SSID router, both need a TP-Link account, and that motor rating rules out a lot of workshop equipment. The deciding difference is one badge.
Where Kasa still wins: outdoors, and on price per bulb
Kasa is not a legacy brand being wound down, and two products in our registry prove it. The Kasa EP40M is the only outdoor plug we track: IP64, rated by TP-Link from −4 °F to 122 °F, Matter-certified, with two independently schedulable outlets and a 15 A / 1,875 W total load with a 1/2 HP motor rating — three times the motor headroom of either indoor plug, which is the spec that decides whether it can run a pond pump.
Its honest cons are the ones TP-Link prints itself: weather-resistant rather than waterproof (avoid water streams, do not immerse, keep it at least 8 inches off the ground), a hard requirement to plug into a GFCI receptacle outdoors or in wet locations, a required free Kasa account, and no published energy monitoring at all.
On the lighting side, the Kasa KL135 is the cheapest color bulb we track and needs no hub, while the Tapo L535E is the Matter-certified one. That is the same trade as the plugs in miniature: Kasa for the price, Tapo for the standard. Our smart bulb ranking puts both against Philips Hue, which is the real competition in that category.
Cameras: not really a contest
TP-Link sells cameras under both brands, but the line it is actually developing is Tapo, and the clearest external confirmation comes from Home Assistant. Its TP-Link integration, which covers both brands with one codebase, states in its supported-functionality section: “Only Tapo cameras, doorbells, and chimes are currently supported.” The supported-device list bears that out — ten Tapo camera models, the Tapo D100C, D130 and D230 doorbells, and no Kasa camera at all.
The Tapo C120 is our pick from that line and the third product on this page: a wired 2K+ indoor/outdoor camera that records to microSD with no monthly fee. The honest cons are the ones we have documented elsewhere: TP-Link publishes 802.11b/g/n 2.4 GHz only for it, it needs mains power so placement is limited by the cable, and TP-Link documents a microphone, two-way audio and sound-based AI detection but no privacy mode, mute or physical off switch — which we cover in detail in our guide to whether security cameras record audio.
One Tapo-specific camera fact worth having before you buy: TP-Link documents that Tapo Care cloud storage, local storage and NAS/NVR recording cannot all be used at once, and that battery and solar models generally do not support RTSP streaming while select wired-and-jumpered doorbells do. The other Tapo-specific fact worth having is about Alexa: TP-Link documents that watching a Tapo feed on an Echo Show “uses internet traffic as a Cloud-to-Cloud service” and stops after ten minutes, which we cover in our ranking of security cameras for Alexa. If you are planning to feed footage into Home Assistant or a NAS, read our Tapo vs Reolink comparison before you commit — Reolink publishes more local destinations.
The two brands compared on what TP-Link publishes
Brand, app-linking, sync and subscription statements are quoted from TP-Link's own support FAQ on linking Kasa devices to the Tapo app; certifications and ratings from TP-Link's US product pages; the camera and IoT-class rows from the Home Assistant project's TP-Link integration page. All read on the date at the top of this page. A dash means the category has no entry in our registry, not that no such product exists. | Kasa | Tapo |

The practical reading of that table: the brands have converged on software and diverged on hardware. One account, one app, two product roadmaps — and Tapo’s is the one getting Matter and cameras.
So which should you buy?
Starting from scratch: buy Tapo. You get the Matter-certified plug, the camera line TP-Link is actually developing, and the app that can also absorb Kasa hardware later if a Kasa product turns out to be the right answer for one room.
Already have Kasa: change nothing. Link it to the Tapo app if you want one app, export any Kasa Care clips you care about first, cancel auto-renewal on Kasa Care before you subscribe to Tapo Care, and expect to re-assign rooms by hand. Your automations come with you.
Buying for outdoors: buy Kasa. The EP40M has no Tapo equivalent in our registry, it is Matter-certified anyway, and its motor rating is the highest of any plug we track.
Running Home Assistant: it genuinely does not matter which brand. One integration covers both, with the same Local Polling IoT class and the same requirement for TP-Link cloud credentials to authenticate local access. Pick on the hardware. Our Home Assistant plug ranking works through exactly which model numbers appear on which supported list, which is the only thing that changes the answer there.
If you are still deciding between ecosystems rather than brands, our smart home ecosystem comparison is the bigger picture, and our best smart plugs page ranks all four of the plugs mentioned here side by side for an ordinary household.
