What is GameTab?

A game-night companion that stays out of the way.

GameTab keeps scores, rounds, player stats, payouts, settlements, tournaments and game history organized in one browser app. It is designed for the part of game night that usually ends up on paper, in calculators, or scattered across phones.

Instead of building another account-based service, I made the public version local-first. There is no backend, database or external API. Your game data stays in the browser.

“I wanted to see how far I could take a game-night utility without accounts, servers, or a database.”
Actual app screens

Built for the phone sitting on the table.

These are real screenshots from the production build running on an iPhone. The interface is mobile-first, with large tap targets, persistent local sessions and a game-night visual system built around dark burgundy, cream and gold.

Local-first architecture

No account. No cloud. No external API.

The official Work #002 release intentionally removes the earlier Supabase sharing layer. Game state and history are stored locally in the browser, so the published app has no backend service, external database or account system.

Built with AI. Refined by actually using it.

GameTab is Work #002 in The AI Ronin Works — an experiment in using AI to build a practical browser tool without requiring AI at runtime.
