Zero Server Costs! A real-time competitive Othello game using only P2P and free services.
This is a real-time Othello game that runs entirely in a browser. It primarily uses P2P communication via WebRTC (PeerJS), allowing game actions between players to be handled directly without a server, thus achieving a low-latency experience. Its key feature is that it can be operated with absolutely no server costs by deploying the signaling server for initial connections on Render’s free tier and the front-end game client on GitHub Pages. You can start a match immediately without any installation just by sending a generated URL to a friend.

Furthermore, the morphing feature lets you generate mesmerizing animations of your images smoothly transforming. All operations are controlled with intuitive sliders, so no expert knowledge is required.

Where the world through my lens and the expressions woven by code meet.
This site is a gallery showcasing my own photography. At the same time, the site itself is a testament to my programming skills. It’s a portfolio that embodies my creativity by fusing the analog sensibility of photography with the digital technology of a website.
