Web Build Host - Local/Public Host & Console for Web Builds

WebGL Build Host runs your Unity Web build on real devices and brings each device's browser console into the Editor. Point it at your build folder, press Start, scan the QR code, and watch what actually happens on the device. 📱 Open the build on any device A QR code and copyable URLs point straight to your build. Served over HTTPS on your LAN, so every device gets the secure context browsers require for camera, microphone, WebXR, and multithreading. Self-healing port selection means a busy port never blocks a start. 🖥️ A live console for every device Each connected browser gets its own Editor tab streaming console output and uncaught errors as they happen. Colour-coded levels, filters, search, frame numbers, and duplicate collapsing. Per-device Reload, Identify, and a one-click Markdown bug report, plus copy, save to file, and clear. 🌐 Optional public link Serve through a free Cloudflare quick tunnel (no account needed) for remote testers, networks that block device-to-device traffic, or phones on mobile data. The window detects cloudflared and shows the install command if it is missing. ⚙️ Loads Unity Web builds correctly Sends the headers Unity needs: .br and .gz encoding, application/wasm, and COOP/COEP, so builds stream in fast and SharedArrayBuffer works. Development Builds are served uncached, so a device reload always picks up your latest build. 🧩 Stays out of your way The server is its own process and keeps serving through recompiles, new builds, and Editor restarts. Dependency-free: a single small native server per Editor OS, no Python or Node. Unity 2022.3 LTS and newer, including the Unity 6 Web platform (WebGL and WebGPU). Editor on Windows, macOS, and Linux.
