What is Karbon Sites?
Karbon Sites is a frontend development environment designed for building and testing web interfaces without needing a full backend setup. It provides a visual playground where developers can prototype, experiment with, and refine frontend code in real time. The tool is particularly useful for designers and front-end developers who want to iterate quickly on layouts, components, and interactions before integrating with production systems. With its freemium model, you can start building immediately without payment, making it accessible for learning and smaller projects.
