About Hasardio
A project born from frustration, built for everyone.
How it all started
It started with a simple frustration: the existing online random picker tools were old, slow, and frankly unpleasant to use. Interfaces from the 2010s, no transparency about the algorithm, and an uncomfortable feeling that you couldn't really trust the result.
In autumn 2025, I needed to run a draw for a personal project — something quick, clean, and that I could confidently show to friends and family. Nothing available met my standards. So I decided to build it myself.
What was meant to be a small side project became Hasardio: a tool I use myself, that my family uses for Secret Santa draws, that my friends use for their giveaways. And apparently, thousands of others had the same frustration.
Who am I?
My name is Julien Buzzi. Entrepreneur at heart, developer in my spare time. I build products that solve real problems — tools I wish I'd had, that I'm proud to put in anyone's hands, for free.

Hasardio's mission
Give everyone — associations, content creators, businesses, families — a truly fair, transparent and verifiable random draw. Not just a number generator: a tool that proves its fairness.
Why SHA-256 certification?
crypto.getRandomValues()
L'entropie vient du matériel de votre appareil — processeur, capteurs, mouvements — pas d'un algorithme logiciel prévisible comme Math.random().
Certificat SHA-256
Chaque tirage génère une empreinte cryptographique unique calculée à partir des participants, d'une seed aléatoire et de l'horodatage. Vérifiable indépendamment.
Zéro serveur pour le tirage
Le tirage se déroule entièrement dans votre navigateur. Vos données ne transitent jamais par nos serveurs. Privacy by design.
Algorithme de Fisher-Yates
Le mélange aléatoire utilise l'algorithme de Fisher-Yates, éprouvé mathématiquement pour garantir une distribution uniforme et sans biais.
