How we build
A small set of proven tools, used well. The same stack runs our own products and is available for custom work.
The stack
Tools we know in depth
Each one is in production today in Atout! and Trick Mates.
- Apps
Flutter
One codebase for the web, Android and iPhone, with interfaces that scale from a phone to a desktop.
- Server
Python and FastAPI
Clear, tested back ends: game rules, real-time tables over WebSockets, accounts and payments.
- Data
PostgreSQL
Relational data with plain SQL migrations, ledgers that add up and backups kept away from the server.
- Web
Cloudflare
Fast static sites, DNS and email routing, with forms that run on the edge.
Practice
What stays the same on every project
The tools change over time. These habits don't.
- Tested
Tests sit beside the code they check, so rules and calculations stay right as the software grows.
- Privacy-first
Collect only what a feature needs, keep secrets off the client, and never sell personal data.
- Accessible
Keyboard and screen-reader support, readable contrast, larger text and reduced motion where people ask for it.
- Resilient
Systems that reconnect, recover and keep their data safe when a network or a server has a bad moment.
- Verifiable
Where trust matters, people can check the result themselves. Atout!'s deals can be verified by anyone after each hand.
