About Plasmic

Plasmic is a visual builder for the web that enables rapidly designing and building applications and websites, with code optional. Its distinguishing idea is codebase integration: you register your own React components so that marketers and designers can arrange them visually, which the project says removes the ceiling usually associated with low-code tools.

The README names three main use cases: content management, where marketing teams drag and drop React components to build landing pages in a Next.js site within design guardrails, applications such as internal tools, client portals and business software built quickly by developers and technical users, and a website builder and design tool that is not limited to a built-in ecommerce platform, CMS or hosting. It works with Next.js, Gatsby and other frameworks, and also acts as a headless CMS.

Plasmic is licensed under MIT and written in TypeScript, with documentation, a quickstart, a forum and a Slack community. The visual editor is offered as a hosted service at plasmic.app, and demos show examples such as a Shopify headless storefront. It suits front-end teams that want non-developers to build with their component library.
