A collection of fast, polished randomizers - text, numbers, wheels, music, movies, games and more. Privacy-friendly by design: no accounts, no tracking, everything runs in your browser.
Live on: userandomize.net
- Text - pick or shuffle lines, weighted picks, password and token generators, random emoji, coin flip
- Numbers - random numbers, dice rolls, lottery draws, random dates, PINs
- Wheel - a customizable spinning wheel of fortune
- Group Shuffler - split people into fair random groups or teams
- Shift Planner - randomized shift assignment across a planning window
- Movies & TV - discover something to watch, filtered by genre, year and rating
- Games - find your next game, filterable by genre, platform, year and rating
- RPS Arena - a rock-paper-scissors battle simulator that runs until one side wins
- Songs - a random track from any artist, album or genre, with an in-page player
All wrapped in light and dark themes, and available in English, Spanish and Slovak.
- Blazor WebAssembly (.NET 9) - the entire UI runs client-side
- Cloudflare Pages and Pages Functions - static hosting and a small serverless API
- JavaScript interop for canvas rendering (the wheel, the RPS arena)
- Bootstrap 5 with custom CSS
Integrates public data from Spotify, Deezer, TMDB, IGDB and others.
- Fully serverless, no backend to babysit - a static WASM front-end with thin Cloudflare Functions that proxy third-party APIs and keep credentials off the client.
- Resilient music discovery - combines Deezer's open catalog for breadth with Spotify for playback, plus caching and graceful fallbacks so it stays fast and within rate limits.
- Hardened API layer - server-authoritative stat counters, per-IP rate limiting, and a spam-proofed contact form.
- Performance-minded UI - composite-only animations and album-art-driven theming for smooth visuals on any device.
- Clean separation of concerns - domain randomization logic lives in its own dependency-free project, decoupled from the Blazor UI.
dotnet build Randomize.sln
dotnet run --project Randomize.WebThe randomizers that call external services run on Cloudflare Pages Functions; the rest of the app works fully client-side.
