Unreal Engine has quickly become a go-to tool for developers, creators, and innovators across industries. Originally designed for gaming, its real-time rendering capabilities and hyper-realistic visuals have propelled it into sectors like architecture, automotive design, film production, virtual reality, and even healthcare simulations. With its powerful visual fidelity and extensive toolset, Unreal Engine has become synonymous with cutting-edge digital experiences.

As industries increasingly embrace remote collaboration and web-based solutions, deploying Unreal Engine projects online has become more important than ever. Web deployment allows developers to reach wider audiences without the need for high-performance local hardware, making it easier to showcase interactive demos, architectural walkthroughs, or immersive experiences across devices. Whether it's for clients, teammates, or global users, the ability to stream or render Unreal Engine projects in a browser is a game-changer.

This is where technologies like Pixel Streaming, WebGL, and WebGPU come into play. Each offers unique pathways for bringing Unreal Engine’s powerful visuals to the web. Pixel Streaming allows you to render graphics server-side and stream the output directly to users' browsers. In contrast, WebGL and WebGPU are browser-based technologies that handle rendering on the user's device, offering varying levels of performance and compatibility.

In this article, we'll dive deep into each technology, comparing their strengths, weaknesses, and ideal use cases for Unreal Engine developers. Whether you're aiming for top-tier visual fidelity or broad accessibility, this guide will help you choose the best solution for your web deployment needs—and show how platforms like Vagon Teams can supercharge your projects with seamless, high-performance virtual collaboration.

What is WebGL?

WebGL (Web Graphics Library) is a JavaScript API that enables interactive 3D graphics directly in a web browser without requiring additional plugins. Built on OpenGL ES, it's designed for compatibility across devices, allowing developers to render real-time graphics directly on a user's hardware.

Why Unreal Engine Doesn’t Natively Support WebGL

While WebGL is widely used for browser-based 3D experiences, Unreal Engine doesn’t offer native support for it. The reason lies in WebGL’s limitations with high-performance rendering tasks. Unreal Engine’s advanced features, such as dynamic lighting, real-time ray tracing, and complex shading, often exceed what WebGL can handle efficiently. As a result, projects built with Unreal Engine tend to require alternative methods for deployment when targeting web platforms.

Workarounds and Limitations

There are third-party plugins and tools that attempt to bridge the gap between Unreal Engine and WebGL. Options like PlayCanvas or Babylon.js allow developers to create 3D content compatible with WebGL. However, these solutions often require simplifying assets, reducing texture quality, or stripping down complex features to fit within WebGL’s constraints. While useful for lightweight demos or prototypes, these workarounds struggle with delivering high-fidelity Unreal Engine experiences.

What is WebGPU?

WebGPU is a cutting-edge graphics API designed to succeed WebGL, offering better performance and more direct access to GPU hardware. Unlike its predecessor, WebGPU supports modern GPU features, including compute shaders and improved parallel processing capabilities.

Advantages Over WebGL

The biggest leap from WebGL to WebGPU lies in efficiency and power. WebGPU provides lower-level access to GPU functions, enabling developers to unlock better performance, especially for complex 3D scenes and real-time rendering tasks. It also offers enhanced support for multi-threading, compute shaders, and larger texture sizes, making it suitable for more graphically intensive applications.

Unreal Engine and WebGPU: Experimental Potential

Currently, Unreal Engine doesn’t natively support WebGPU, but the future looks promising. As WebGPU matures and browser support expands, there’s potential for tighter integration with engines like Unreal. Experimental projects have shown that leveraging WebGPU could dramatically improve browser-based Unreal Engine applications. However, until native support becomes available, developers will need to experiment with custom rendering pipelines or wait for official support.

How Pixel Streaming Works with Unreal Engine

Pixel Streaming is a feature built directly into Unreal Engine, allowing developers to render graphics server-side and stream the output as a video feed to a web browser. Instead of relying on the user’s device for rendering, the server handles all graphical computations and sends a high-quality video stream in real-time.

Benefits of Server-Side Rendering

The major advantage of Pixel Streaming is that it delivers high-fidelity visuals regardless of the end-user’s hardware capabilities. Since the rendering happens on a powerful server, even devices with limited resources can run intensive Unreal Engine applications smoothly. This makes it an ideal solution for interactive experiences that demand high resolution, advanced lighting effects, and complex simulations.

Challenges: Bandwidth, Latency, and Cost

Despite its strengths, Pixel Streaming isn’t without challenges. Streaming high-resolution graphics requires substantial bandwidth, and latency can affect user experience, especially for interactive applications like games or simulations. Additionally, running Unreal Engine instances on cloud servers can be costly, particularly for projects expecting high traffic or requiring always-on availability. Balancing performance and cost becomes essential when scaling Pixel Streaming solutions for larger audiences.

Key Aspects for Comparison

When rendering happens locally through WebGL or WebGPU, the user’s device handles all the heavy lifting. Performance depends entirely on the device’s hardware capabilities. This works well for lightweight applications or those with simplified graphics, but it can struggle with Unreal Engine’s high-end visuals. In contrast, Pixel Streaming shifts rendering tasks to a remote server, delivering consistent performance regardless of user hardware, though it introduces potential latency due to network communication.

Unreal Engine's advanced features like dynamic lighting and real-time ray tracing often push local rendering to its limits. WebGL and WebGPU require asset optimization to maintain smooth performance across different devices. Pixel Streaming, however, preserves full visual fidelity because rendering happens server-side, ensuring users experience Unreal Engine’s capabilities without hardware constraints.

Pixel Streaming centralizes performance control, making it easier to support large audiences simultaneously. This scalability comes with higher server demands, meaning more resources are needed to handle increased traffic. On the other hand, WebGL and WebGPU scale more efficiently on the client side, though users with older devices might face performance issues.

Cost is another critical factor. Pixel Streaming requires powerful servers capable of managing real-time rendering for multiple users, and hosting costs can escalate quickly for high-traffic applications. WebGL and WebGPU are generally more cost-effective since rendering happens locally, reducing server-related expenses. They are ideal for smaller projects or lightweight interactive content with moderate performance requirements.

Pixel Streaming is the best choice for applications where visual fidelity cannot be compromised. Architectural visualizations, VR/AR experiences, and simulations benefit from high-quality server-side rendering that remains consistent across devices. Conversely, WebGL and WebGPU are better suited for projects focusing on accessibility and broader device compatibility. They work well for interactive educational tools, simple 3D games, or product configurators where performance demands are lighter and visual complexity is more manageable.
