8th Wall Is Now Open Source: What This Means for Web AR in 2026
The 8th Wall WebAR platform has gone open source after years of costing developers thousands per month. Here's what changed, what's included, and why now is the best time to build augmented reality for the web.
If you've worked in web-based augmented reality over the past few years, you'll know 8th Wall. It was the go-to platform for building AR experiences that ran directly in the browser, no app download required. It was also expensive, often prohibitively so, with commercial licenses running between $700 and $3,000 per project per month.
That's changed. As of February 2026, Niantic has wound down the 8th Wall platform and released its core technology as open source under an MIT licence at 8thwall.org. The engine binary, which includes world tracking and SLAM capabilities, is now free to use commercially with no login required.
This is a significant shift for the WebAR industry. Here's what it means if you're considering building AR for the web.
What's Actually Included
The open source release at 8thwall.org includes:
- Image Targets - Detect and track real-world images through the camera
- Face Effects - Face mesh tracking for filters and overlays
- Sky Effects - Sky segmentation and replacement
- ECS Runtime - The entity-component-system framework for building experiences
- Desktop App - Local development environment
- Documentation and examples - Full docs and sample projects on GitHub
The core engine binary, which handles the heavy lifting like world tracking, absolute scale, and SLAM (simultaneous localisation and mapping), is distributed as a free closed-source binary. You can't modify the engine itself, but you can use it commercially in your projects without restriction.
What This Means in Practice
The technology that was previously locked behind enterprise pricing is now available to everyone. To put that in perspective:
- An agency running three AR campaigns would have been paying $2,100-$9,000 per month in 8th Wall licences alone
- A startup building an AR product viewer would have needed to factor in ongoing per-project costs before writing a line of code
- An indie developer experimenting with WebAR was effectively priced out of the most capable platform
All of that cost is now zero. The barrier to building professional-grade web AR has dropped dramatically.
Why Web AR Makes Sense for Businesses
The real advantage of WebAR over native AR apps has always been distribution. Users scan a QR code or tap a link and the experience loads instantly in their browser. No app store, no download, no friction.
This matters because:
- E-commerce product visualisation - Let customers see furniture in their room, try on accessories, or preview products in 3D before buying. The conversion lift from AR product viewers is well documented.
- Marketing campaigns - AR experiences on packaging, print materials, or in-store displays. The reach is immediate since anyone with a smartphone browser can participate.
- Education and training - Interactive 3D models and overlays that work on any device without IT deployment headaches.
- Real estate - Virtual staging and property visualisation through a simple link.
With browser support for WebXR now available across Chrome, Edge, and Samsung Internet, and improving on Safari, the technical foundation is solid. Over 3 billion devices worldwide can run WebAR experiences today.
The WebAR Landscape in 2026
8th Wall going open source is part of a broader shift. The WebAR ecosystem is maturing rapidly:
- WebXR Device API is now a stable browser standard with wide support
- Three.js continues to be the backbone of 3D web development, with excellent WebXR integration
- Google's Model Viewer web component makes basic 3D product visualisation trivially easy to implement
- A-Frame and AR.js provide accessible entry points for developers new to AR
- 8th Wall's engine now gives everyone access to the most advanced world tracking available on the web
The cost of entry has never been lower, and the capabilities have never been higher. If you've been waiting for the right time to invest in AR for your business or product, this is it.
What You Need to Know Before Building
A few practical considerations:
- Self-hosting is required. The 8th Wall cloud platform is gone. You'll need your own hosting infrastructure, which any competent web development team can handle.
- The engine binary won't be maintained forever. Niantic isn't actively developing 8th Wall anymore. The open source community will drive future improvements to the MIT-licensed components, but the closed-source engine binary is as-is.
- WebAR has limitations. It's excellent for marker-based experiences, face filters, and product visualisation. For persistent world-scale AR or multi-user shared experiences, native solutions like ARKit and ARCore still have the edge.
- Performance varies by device. Budget and mid-range phones handle simple experiences well, but complex scenes with heavy 3D models need optimisation. This is where experienced developers make the difference.
Getting Started
If you're exploring WebAR for your business, the approach I'd recommend is:
- Define the use case first. What problem does AR solve for your customers? Product visualisation, interactive marketing, training?
- Start with a proof of concept. A focused prototype validates the idea and surfaces technical constraints early.
- Choose the right tools. For simple 3D product viewers, Google's Model Viewer might be all you need. For interactive, tracked AR experiences, 8th Wall's open source engine is now the obvious choice.
- Plan for performance. 3D asset optimisation and testing across devices is critical for a good user experience.
