Figma

Figma defined modern collaborative design — real-time multiplayer editing, component systems, and browser-based access transformed how design teams work. But Adobe's acquisition, increasing pricing ($15/editor/month for Professional), and concerns about vendor dependence have sparked interest in open source alternatives.

Penpot is the leading open source design tool — it offers real-time collaboration, component systems, and a browser-based interface similar to Figma. Its key differentiator is using SVG as the native format, meaning your designs are in an open standard rather than a proprietary format. Penpot also supports CSS Grid and Flexbox layouts, aligning design output more closely with how developers build. Excalidraw provides a different value — it's a virtual whiteboard optimized for diagrams, wireframes, and sketches with a hand-drawn aesthetic that's perfect for brainstorming and technical diagrams.

The practical question is feature parity. Figma has years of development invested in Auto Layout, Variables, Dev Mode, prototyping, and a massive plugin ecosystem. Penpot covers the fundamentals well but doesn't yet match Figma's depth in every area. For teams doing complex design systems with hundreds of components, Figma's maturity is still an advantage. For straightforward UI design, wireframing, and teams that prioritize open standards, Penpot is ready for production use.

The self-hosting option matters for organizations working on sensitive projects — product designs for unreleased features, financial applications, or government projects where design files shouldn't live on external servers.
