Reviewer scorecard
“My go-to for system architecture diagrams. The hand-drawn style makes diagrams feel approachable rather than intimidating. Real-time collab works flawlessly.”
“Embed interactive 3D in React with one line. The export options and API make integration seamless.”
“The aesthetic is the differentiator. Every diagram looks friendly and informal which makes it perfect for presentations, blog posts, and documentation.”
“3D design that's actually fun and accessible. The learning curve is dramatically lower than Blender or Cinema 4D.”
“Simple, fast, free. Does one thing well. The library system for reusable components is useful. Not trying to be Figma and that is a strength.”
“For web-native 3D, Spline is the clear winner. The browser-based editor and embedding are perfectly designed.”
