Online Design Tools

104 resources

This is the broadest category: tools that run in the browser for designing, diagramming, editing images and generating CSS. It includes design apps like Figma and the open-source Penpot, Photopea and other browser image editors, diagram tools like Excalidraw, diagrams.net and Mermaid, background removers, and many single-purpose CSS generators for grids, clip-paths, shadows and scrollbars.

For interface design, Figma is the industry default, and Penpot is an open-source, self-hostable alternative built on SVG. Photopea opens PSD files in the browser, which is useful when a client sends a Photoshop file. Excalidraw produces hand-drawn style diagrams, while diagrams.net and Mermaid suit architecture docs, and Mermaid diagrams live as text in your repository.

The CSS generators save time on syntax that is easy to forget: Clippy for clip-path, Fancy Border Radius for organic shapes, Grid Layoutit and the other grid generators for grid-template areas, Josh Comeau's Shadow Palette Generator for layered shadows, and Scrollbar.app for custom scrollbars. Carbon and Ray.so create code screenshots. Many newer tools process files locally in the browser, which is worth preferring for private images.
