Faceplate — a visual UI designer for JUCE WebView2 plugins

[AllTheMachines]

Just went public: https://github.com/AllTheMachines/Faceplate
if you build synths, effects, or instruments, you know the pain: designing knobs, sliders, meters… then hand-coding all of it in C++.
JUCE 8 introduced WebView2 support, which means your plugin UI can now be built with HTML, CSS, and JavaScript — running inside your VST3/AU/AAX.
Faceplate is a visual designer for that workflow.

How it works:
Drag UI elements onto a canvas → tweak size, color, behavior → see it live → export a ready-to-use WebView2 bundle (HTML/CSS/JS) that talks to your C++ parameters.
No more recompiling to tweak a knob color.

Features:
- 60+ UI components (knobs, sliders, VU meters, waveform displays, panels)
- Real-time preview
- Multi-window layouts (main, settings, dev windows)
- SVG import with automatic layer detection
- Exports working code with JUCE parameter bindings

Who it's for:
Audio developers who want to use modern web tech for plugin UIs — or just want to stop fighting JUCE's GUI classes.

Status: Public and usable, but still evolving. Bugs expected — feedback welcome.

Hi there,

I just saw your post about Faceplate and this sounds absolutely incredible. I am currently developing a modern guitar DSP suite (Autima DSP) using JUCE, and I completely bypassed the native C++ GUI classes in favor of a WebView2 (HTML/CSS/JS) architecture. It has been a total game-changer for styling and workflow.

A visual designer tailored specifically for this JUCE/WebUI bridge is exactly what the community needs right now.

However, I tried to access your repository to test it out, but the GitHub link is currently returning a 404 error. Did the repository get switched to private or perhaps the URL changed?

I would love to give it a spin, especially to see how it handles the SVG imports and the parameter bindings compared to my current manual setup. Let us know when it's back online!

Cheers,

[Mr D]

Demo video?

Yeah more info please, visuals of the gui, or examples?

A few companies use webview for their plugins, not fond of it myself. Though I bought their
plugins despite that. Sometimes it prevents them from working if your internet is slow or out.
They check for updates every time you start them as well.
