Jigsaw - Modern multiplayer jigsaw puzzles in the browser

Our office removed the physical puzzle, so I built a multiplayer one. A coworker and I use it daily for a couple of hours. You can upload your own images and choose the number of pieces and the piece shape. Share the room link and others can join and solve with you in real time. There are a lot of keyboard shortcuts and power-user features. Stack: React, TypeScript, Vite, Node, WebSockets, SQLite, running on a Hetzner VPS. Pieces are rendered with WebGPU because it was fast and smooth.
