Plasmic is a visual builder and headless CMS for front-end development. Designers and developers compose pages and components in Plasmic Studio, then ship them via either the Headless API (Loader) for runtime fetching or the Codegen pipeline for generated React/Next.js/Gatsby source. The platform also exposes a CMS for structured content, a CLI for code synchronization, and a REST API for programmatic access. Open source components live under the plasmicapp GitHub organization.
