MightyMeld is a visual development tool that shows your code alongside your app's live DOM, letting you tweak styles and drag elements with instant code.

MightyMeld is a developer tool that makes web code visual. It displays your code alongside the live DOM of your running app, so you can tweak styles, drag elements around, and experiment with visual changes while your code updates instantly. Users describe it as bringing Figma-like capabilities to frontend development: you can make precise, structure-aware changes to your code without relying on code generators or constantly switching between your browser and your code editor. MightyMeld also produces clean code differentials, so you can see exactly what changed.
MightyMeld was started by a team with the goal of making web code work visual and aligned with how engineers prefer to code. The core team includes Tim, Steven, John, and Daniel. Tim and Steven both have experience from Happy Returns, John brings a deep understanding of Haskell compilers, and Daniel has a background at Brand.ai and InVision. The product has officially launched.
MightyMeld is aimed at frontend professionals, including senior frontend developers, software engineers, frontend engineers, and frontend developers who also create content.
