Pixel Streaming has unlocked a powerful idea: running Unreal Engine experiences directly in the browser.
But anyone who has shipped a real project knows the hard truth, video streaming is the easy part.
The real challenge is interaction: turning web UI actions into reliable, structured Unreal gameplay logic, and sending state back to the browser in a clean, scalable way.

Pixel Streaming Bridge (PSB) exists to solve exactly that.

PSB is not just another helper plugin. It is a professional Unreal ↔ Web integration layer, designed to make Pixel Streaming behave like a first-class citizen inside modern web applications.

From “Video Stream” to Real Web Application

Out of the box, Pixel Streaming gives you input events (mouse, keyboard, touch).
What it does not give you is a robust way to:

  • Drive Unreal logic from UI buttons, sliders, forms, or dashboards

  • Synchronise application state between Unreal and the browser

  • Scale interactions without writing fragile, ad-hoc JavaScript and Blueprint glue

PSB introduces a structured data bridge between Unreal and the web.
Web UIs send clearly defined commands. Unreal responds with structured events.
And it does seamlessly, with almost no effort.

This is what allows Unreal experiences to feel like part of a real web product, not just a streamed viewport.

UI-First by Design

A core philosophy behind PSB is that the UI is not an afterthought.

Every serious Pixel Streaming project eventually needs a strong web interface:
product configurators, dashboards, training panels, control rooms, CMS-driven experiences.
PSB embraces this reality instead of f

Reference UI Included

PSB ships with a modern Next.js / React reference UI, built to demonstrate best practices:

  • Clean component structure

  • Typed command sending

  • Responsive layouts

  • Glassmorphism-inspired, production-ready aesthetics

  • Seamless iframe embedding

This UI is not a demo prototype. It is a starting point, meant to be extended or replaced.

Case-Specific UI Templates (Roadmap)

PSB is designed to grow beyond a single reference UI.
Future updates will introduce ready-made, case-specific UI templates, such as:

  • Product configurators (materials, variants, pricing logic)

  • Virtual showrooms and sales experiences

  • Enterprise dashboards and control panels

  • Training and simulation interfaces

Each template will focus on real-world UX patterns, not flashy experiments, helping teams ship faster without reinventing the same UI logic again and again.

Why Choose Pixel Streaming Bridge?

PSB is built for developers and studios who need predictability, safety, and scalability.

Provider Agnostic

PSB works seamlessly with:

  • Epic Cirrus

  • Arcware

  • Eagle 3D

  • Vagon

  • Local or custom signalling servers

Your Unreal logic stays the same. Providers remain a deployment detail, not a technical constraint.

Structured Messaging

All communication follows a strict JSON envelope (PSB Envelope v1.0).
Only valid messages reach your game logic, protecting your project from malformed or unsafe input.

A Bridge, Not a Shortcut

Pixel Streaming Bridge is built with a long-term mindset.
It does not hide complexity, it organises it.
It does not lock you into a provider, it abstracts them away.
And it treats the web UI as a first-class system, not a side panel.

If your Unreal project needs to live inside a professional web ecosystem,
PSB is the missing piece between your 3D world and your users.
