Domain Rating – a leaderboard of startup website Domain Ratings
Ahrefs API wrapped in a retro leaderboard — TrustMRR but for domain rating.

Elo leaderboard for game nights, but dozens of free Discord bots do exactly this.
Friend groups playing competitive games together

I built Shmelo as a little break from work stuff.
Its a simple leaderboard for games with friends: set it up fast, log games, share a public link.
Works with any game as long as it has winners and losers.
Rankings use elo system (like chess). it stays fair even if people miss a few sessions. You can also see how rankings change over time, and tap into more stats if you want.
Feedback appreciated.
Cheers!

Wordle-style daily puzzle but for spatial reasoning instead of words.
Multiplayer 2048 with ELO ranking, but countless clones already exist.
Gamifies commit counts, but GitHub's own contribution graph already solves this.
The author actually built a proper server-authoritative game using Rust + Tokio and Tungstenite, then added 4-player ELO quick queues, best-of-N lobbies and global leaderboards — not just a demo. The UI looks inviting, but the product hinges on live player density (no bots yet) and raises questions about latency handling, cheat prevention and scaling as the leaderboard grows.
Elo-rated head-to-head voting for trivial debates like best Office character.
