About QuizBase
I built QuizBase because I needed it myself.
TL;DR
- QuizBase is a multilingual trivia API with an open CC BY-SA dataset.
- It is run by Maciej Dzierżek — a one-person studio in Poland.
- The main value is the API: fast, multilingual, easy to plug into anything.
- The dataset stays open. The API is the product.
I have loved playing Buzz and similar trivia games for years. I no longer have those consoles, but along the way I discovered that I enjoy hosting quizzes even more than playing them — for friends, at family events, and during corporate training sessions I run.
Every time I needed a fresh batch of questions I hit the same wall: there is only so much you can make up on the spot, and the public trivia datasets are scattered, English-only, or hard to use programmatically. So I built QuizBase: a single API that returns clean, categorised, multilingual questions sourced from open datasets and refined with care.
RunRiva — a product still in the making — will be the first thing built on top of QuizBase. But I never wanted this to be a private moat. The sources I draw from are open, so I keep my work open too. The dataset is published under CC BY-SA. The API is the product; the data is the commons.
In 2026 anyone can be a developer, and anyone can build a quiz game in many languages without inventing the questions themselves. That is the world I want to make slightly easier.
Who is behind QuizBase
Since 1996 I have been working in and around the internet and digital products. I have been a product manager, worked on large portals, small fan sites, and corporate transformations. Change has been the one constant in my professional life — and this project is part of the change happening around us.
I live and work in Poland. More about me and what I write about is on maciejdzierzek.com.
What QuizBase stands for
Transparent service
Clear pricing, clear limits, clear licensing. No dark patterns, no surprise charges, no vendor lock-in.
Open data, useful API
The dataset is CC BY-SA and freely downloadable. The value you pay for is the API: speed, multilingual coverage, and easy integration.
Built for developers — human and AI
REST, MCP, TypeScript SDK. A developer (or an AI coding agent) should get exactly what they need with the least possible friction.
A long game
The goal is for QuizBase to become the largest stable, affordable, multilingual trivia base on the planet. Built to last.
