In short: brief the experience, not the standard. Ask for WebAR that works on iPhone Safari and Android Chrome, and let the studio choose the tracking engine.
WebAR and WebXR are not two competing products
The two terms get mixed up in briefs, and the mix-up leads to the wrong questions. WebAR describes what a person experiences. WebXR describes one way a developer can build it.
| Term | What it is | Who needs to care |
|---|---|---|
| WebAR | An AR experience opened from a link or QR code in a phone browser, no app install | The brand: it is the thing you are buying and the way people reach it |
| WebXR | A browser standard (the WebXR Device API) that lets web pages use AR and VR hardware features | The developer: it is one possible way to build WebAR |
| Quick Look | Apple's built-in viewer for placing a 3D model in your room from iPhone | Anyone showing a product on iPhone without custom tracking |
Why iPhone changes the brief
In the 2026 sources we checked, Safari on iPhone does not support WebXR AR sessions, while Chrome on Android does. Every browser on iPhone runs on Apple's WebKit engine, so switching browsers does not fix it. Apple's headset browser has added WebXR support, but that is not the audience of a consumer campaign. Treat browser support as a fact to re-check before any build, because it has moved before.
That is why a lot of brand WebAR is not built on WebXR at all. Many WebAR engines do the tracking themselves inside the web page, so face effects, image targets and world tracking can work on both iPhone and Android. Our HP product launch WebAR activation, built in 2024 on 8th Wall, worked this way: attendees scanned a code and launched it in the phone browser with no app. A note on the platform risk: 8th Wall's hosted service has since shut down and its engine is open source, which we cover in Camera Kit vs 8th Wall.
Nobody has ever remembered a campaign for the browser API under it. They remember what happened when they pointed the camera.
What to put in a WebAR brief instead of "use WebXR"
- Describe the moment. What does the person see, and what do they do? A product on a table, a character in a room, a face effect.
- Name the test devices. Ask for it to be tested on iPhone Safari and Android Chrome, and say which phones you expect your audience to hold.
- Ask what happens when it fails. A denied camera permission, a weak venue connection, an older phone. The fallback is part of the experience.
- Ask where it is hosted and for how long. A link on a pack outlives a campaign. Point it at a URL you control.
- Ask what the engine is and who maintains it. The 8th Wall change is the reason to ask.
How to choose the web route from the story
The tracking engine is a production decision and belongs with the studio. The creative decision is what the person should feel standing there with their phone up. A product they can place in their own space, a character that appears on a landmark, a face effect that becomes a clip, a world they step into: each one points to a different build, and each one can run in the browser. See WebAR for brands and what is web AR for the format basics, and real WebAR examples for deployed work, including 007 First Light. WebAR experiences typically start around $8k, with the breakdown in how much an AR filter costs.
Frequently asked questions
Is WebXR the same as WebAR?
No. WebAR is the experience: AR that opens from a link in a phone browser with no app. WebXR is a browser standard developers can use to build it. WebAR can be built with WebXR or with engines that do their own tracking inside the page.
Does WebXR work on iPhone?
In the 2026 sources we checked, no. Safari on iPhone does not support WebXR AR sessions, and every iPhone browser uses Apple's WebKit engine. Chrome on Android does support it. Re-check before a build, because browser support changes.
Does a brand need to ask for WebXR?
No. Ask for a WebAR experience that works on iPhone Safari and Android Chrome and describe what the person should see. The studio chooses the engine. Naming a standard in the brief tends to narrow the options without improving the result.
Does WebAR need an app?
No. WebAR runs in the phone's browser. A person scans a QR code or taps a link, grants camera access, and the experience starts. That is why it suits events, packaging and anything that has to work for a crowd.
What happened to 8th Wall?
8th Wall's hosted platform was wound down in 2026 and its engine was released as open source. Brands that built on it need a plan for hosting and maintenance. Our Camera Kit vs 8th Wall guide covers what that means for a brief.
