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:

• React component – embed the canvas directly in your own app, or bring your own React components into it
• Modular SDK – build custom tools on top of Grida's core rather than being locked into the default interface
• Scripting interface – automate design tasks and write plugins using a runtime scripting layer
• Performance – compute-heavy modules run on Rust and WebGPU, which matters when you're working with complex documents or large canvases

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.
