As answered by people managing Diceonaut and Diffyn.
Diceonaut's answer
Diceonaut puts nine classic board and skill games — Ludo, Carrom, 9-Ball Pool, Connect 4, Quoridor, Gomoku, Snakes & Ladders, Tic-Tac-Toe and Duel Deck — in a single browser portal with nothing to download, install or sign up for. You open a game, share a private room link, and a friend is playing with you in about five seconds. Every game runs online against real players, against AI, or pass-and-play on one device, with real board physics for Carrom and 9-Ball. It's completely free, not pay-to-win, has no real-money gambling, and works on any phone, tablet or desktop.
Diffyn's answer:
Addresses workflow and change management on LLM prompts, provide teams with traceability and visualization of tests across multiple models, provide deeper understading into efficiency of these prompts.
Diceonaut's answer
Most classic-game apps make you install a separate app per game, create an account, and wade through ads and pay-to-win mechanics. Diceonaut is the opposite: one browser link, no install, no sign-up to start, many games in one place, and no paywall on gameplay. Challenging a friend is a single shared link rather than "download this app first." It's genuinely free and safe — no real-money gaming — and the same account works across the web and the Android app.
Diffyn's answer:
Diffyn is the platform that specializes on both change management and multi-model analysis.
Diceonaut's answer
Go (real-time, authoritative game backend), React and Phaser (browser frontend and game canvas), WebSocket for live multiplayer, Redis for coordination and PostgreSQL for persistent data, served behind Cloudflare. Available on the web and as an Android app.
Diffyn's answer:
React, Next.js, POSTGRESQL
Diceonaut's answer
Casual players, friends and families who want to play familiar board and skill games together quickly — without everyone installing the same app. It resonates strongly with players of Ludo and Carrom (huge in India and the wider South Asian diaspora) while staying broadly appealing to anyone who enjoys quick, social, classic games on any device. Skews mobile-first and social (play-with-a-friend), not hardcore or competitive-esports.
Diffyn's answer:
Professionals incorporating LLMs or AI tools in their workflow and wants to keep track of changes and test their prompts.
Diceonaut's answer
Diceonaut started from a simple frustration: wanting to play Ludo and Carrom with friends without everyone having to install a different app, make an account, and sit through ads. So we built a browser-based portal where classic board and skill games just work — share a room link and you're in a game in seconds. It grew into a full catalog of nine games with online multiplayer, AI opponents, leaderboards and a shared in-game economy, all free and running right in the browser.
Diffyn's answer:
I started working on Diffyn when I notice that prompting has become an essential part of work across many industries. While there are version control platofrms like github, they are not designed for just prompt management are can be overkill such applications, it is also not integrated natively with various LLMs and relevant tools for users to validate ideas and visualise results properly.
