本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
Penpot stands out with Open source and self-hostable and SVG-native design. Spline counters with Browser-based 3D modeling with real-time collaboration and 3D animations and interactive scenes without code.
Penpot's Achilles heel: still catching up to figma on polish and plugin ecosystem — feels rough around the edges. Spline's: not a replacement for serious 3d work — geometry tools are basic compared to blender or cinema 4d. Pick whichever weakness you can live with.
結論
If you value open source and self-hostable and ベンダーロックインなしでセルフホスト可能なfigma代替を求めるオープンソース支持者, go with Penpot. If blenderやunityを触らずにwebサイトに3dを入れたいwebデザイナーやフロントエンドdev matters more, Spline is your pick. Neither is a bad choice — but one will fit your workflow better.
