Design and build web applications on an open canvas with AI-powered tools, Figma integration, pixel drawing, and a modular SDK built for extensibility.

Grida is an open source canvas editor aimed at designers and developers who want a single tool for visual design and web app building. It covers the range from polished UI/UX layouts to pixel art, with enough extensibility that developers can embed it, script it, or build entirely new tools on top of it.
The canvas itself is general-purpose. You can work from templates, drag in widgets and icons, write copy with an AI assistant, and edit text directly on the canvas. Figma import and export means you're not starting from scratch if your team already has assets in Figma. For pixel work, there's a dedicated free pixel drawing mode built into the same editor.
What separates Grida from tools like Penpot or Excalidraw is its developer-first architecture:
For teams, Grida offers enterprise options with on-premise deployment and custom solutions, so it's not just a solo design tool.
It fits developers who want a visual web builder they can actually hack on, and designers who need something between a lightweight whiteboard and a full-featured UI tool.
