Webstudio

Webstudio is an open source visual development platform for developers, designers, and cross-functional teams. It is built for creating websites while keeping the data, components, and infrastructure under your control, with a hosted version available or the option to roll out your own.

The visual editor gives you access to every CSS property and value, plus reusable styles and design tokens without writing classes, and it connects to any headless CMS. It is built around modern web standards so the sites it produces stay maintainable and fast.

Webstudio is built by Webstudio, Inc., and its core is free and open source under AGPL-3.0-or-later. You can use the hosted service or run your own on infrastructure you control. One optional animation package is proprietary and requires accepting a separate EULA before use.
