8th Wall vs. Unreal Engine

Q: How does Needle Engine compare to 8th Wall?

8th Wall specializes in high-quality markerless mobile WebAR using a proprietary engine and usage-based pricing. Needle Engine is a more versatile spatial web platform covering AR, VR and screen-based 3D, built on three.js and WebXR with Unity/Blender authoring and predictable per-seat pricing. Choose 8th Wall for best-in-class AR campaign tracking; choose Needle for broader, standards-based web 3D/XR.

Q: How does Needle Engine compare to Unity's WebGL export and Unreal Engine?

Unity's WebGL export compiles the whole Unity runtime to WebAssembly, producing large, slower-loading sandboxed builds without AR/VR support; Unreal has had no WebGL export since 4.24 and relies on costly pixel streaming. Needle Engine instead exports glTF plus JavaScript/TypeScript to a lightweight three.js runtime, giving small, fast-loading apps that integrate with web frameworks and support WebXR and USDZ.

How does Needle Engine compare to 8th Wall?

8th Wall is a web platform focused on providing high-quality markerless WebAR experiences via its proprietary technology and cloud editor. Both Needle Engine and 8th Wall enable the creation and deployment of Augmented Reality content on the web, though they differ significantly in workflow, underlying technology, and scope.

	Needle Engine	8th Wall
Editor	Integrates with familiar tools: Unity & Blender	Primarily uses its own web-based Cloud Editor and direct coding against its API.
Core Tech	Uses three.js; Focus on glTF standard; WebXR for AR/VR. Web-native design.	Proprietary engine & rendering pipeline. Highly optimized for its specific tracking tech.
Primary Focus	Flexible Spatial Web Platform: Building 3D web apps, VR, AR & web integrations.	Advanced Mobile WebAR: Specializes in high-quality markerless (SLAM) tracking.
Workflow	Leverage Your Existing Skills: Export optimized projects from Unity/Blender.	Web-Centric API/Editor: Build directly for the web using 8th Wall's tools and JS API.
AR	Broad WebXR Support: Handles various AR modes based on web standards.	Industry-Leading SLAM: Excels at markerless world tracking on mobile devices.
VR	Strong Support: Built natively on the WebXR standard for VR experiences.	Limited/Not Primary Focus: Primarily designed for mobile AR, not VR headsets.
Flexibility	High: Designed for npm/web components, easy embedding into existing web apps.	Moderate: Primarily API-driven integration for AR features within a web page.
Pricing Model	Tiered: Predictable per-seat options suitable for teams.	Usage-Based: Often priced per view/impression, scales with traffic.
Target User	Devs/Teams wanting optimized web 3D/XR integrated from Unity/Blender or web developers who want to integrate 3D content into their web applications.	Devs/Agencies needing best-in-class markerless WebAR tracking, often for campaigns.

8th Wall provides excellent markerless WebAR tracking. However, we designed Needle Engine for developers and teams looking for a more versatile solution. If you want to leverage your existing Unity or Blender skills, build a broader range of spatial web experiences (including AR, VR, and screen-based 3D), prioritize performance and integration with standard web technologies, and prefer predictable licensing, then Needle Engine is likely a great fit for your project.

How does Needle Engine compare to Unity's WebGL export and Unreal Engine?

We get this question a lot!

With Needle, projects use standard web technologies like HTML, CSS and JavaScript. They can seamlessly integrate in existing web applications and frameworks like React, Svelte, and so on. Needle projects load very fast, and can use AR and VR features via WebXR and USDZ. Apps made with Needle can also easily use accessibility features like screen readers or translations.
With Unity, you can export projects to WebAssembly and WebGL, making them run in browsers in a self-contained sandbox. Connecting them to existing web applications is possible, but requires a lot more developemnt work. Unity WebGL projects are usually larger and much slower to load than Needle projects, and neither support AR/VR features nor accessibility solutions.
Unreal does not have WebGL build support since version 4.24. It supports pixel streaming (a server renders the scene, and there's a video stream to the user's machine), which is a prohibitively costly solution for most use cases, and does not support AR/VR.

	Needle Engine	Unity WebGL Export
Editor Environment	Integrates with existing desktop editors (Unity, Blender)	Uses the standard Unity Editor (Desktop)
Core Tech	three.js runtime; Focus on glTF standard. Web-native design.	Unity Runtime compiled to WebAssembly (Wasm) + WebGL.
Workflow	Integration & Optimization: Export data (glTF) & logic (JS/TS) from editors to a lightweight web runtime. Fast iteration.	Direct Platform Port: Compile/Build the entire project (or subset) for the WebGL platform target from within Unity.
Scripting	TypeScript / JavaScript (Runs directly in the browser)	C# (Compiled via IL2CPP to C++ then Wasm)
Collaboration	Editor features (Unity/Blender Collab) + Git. Built-in networking.	Unity Collab, Plastic SCM, Git, etc. (Standard Unity workflow)
Key Features	Web-Optimized: glTF pipeline, smaller builds, faster loads, PBR, lightmaps, XR, npm/web components, networking. Leverages web standards.	Broad Engine Access: Uses many core Unity features (URP, Physics, Animation, UI). Asset Store access. Potential for larger builds/load times.
Feature Parity	High: Translates a defined set of editor features reliably to web standards (glTF, JS/TS).	High (but not 100%): Aims for high parity, but some engine features may not work or perform well in WebGL.
Flexibility	High: Designed for easy integration into web apps (npm, components).	Moderate: Embeddable builds. JS Interop for communication with web page. Less seamless than native JS frameworks.
Performance	Optimized for Web: Generally yields smaller builds and faster load times due to web-native architecture.	Variable: Can be powerful but may carry overhead from the engine. Build size/performance depend heavily on project complexity & optimization.
Pricing	Tiered: Free / Paid per seat options.	Tiered (Standard Unity): Personal/Plus/Pro/Enterprise. Potential Runtime Fees.
Target User	Devs needing optimized, integrated web 3D/XR from Unity/Blender workflows.	Devs porting Unity projects to web or needing the broad Unity ecosystem for complex web games/apps.
