ESP32-WebBuilder - a visual tool for designing ESP32 web interfaces

[g9Six]

I started building a browser tool where you drag and connect modules — Pages, Sensors, Forms, Cards, APIs, Storage — to lay out the website your ESP32 serves. Hit Generate and you get a complete, self-contained .ino with WiFi setup, routing, HTML rendering, and sensor reads wrapped in a clean EmbeddedSite class. Set your credentials and flash.

Highlights:

Live preview (with phone-frame toggle) before you compile

Form → Storage flow that saves to NVS, plus a node to read values back

WebServer or AsyncWebServer backend

Configurable site theme colorset, baked into the generated code

Import/Export diagrams as JSON

All client-side, no install, no backend, or bloated frameworks. Putting it out for feedback — curious what you think of this kind of workflow and code generation, and what modules you'd want. Mongoose Wizard kicks butt, so is there a place for a simple tool concept like this?

Looks promising but why paid .... keep it free at start .... but i think it has a future .... add some AI stuff, it usually attracts

[g9Six]

Thanks.  There is still a free tier.

The "Preview" doesn't show anything relevant? Can't see what kind of thing it can make without making an account?

[g9Six]

Correct, maybe "preview" isn't the best term.
