How these tools work
Fun and practical generators. Create QR codes, roll random numbers within any range, generate random names and split a list into balanced teams, plus a wheel spinner for fair decisions. Every tool in this category publishes its formula, worked example and assumptions so you can verify the result yourself.
Frequently asked questions
Are the random numbers truly random?
Random numbers use the browser's cryptographic random generator (crypto.getRandomValues), which is designed for unbiased, unpredictable values.
Is the QR code generator free to use?
Yes, and it runs entirely in your browser. Your data is never uploaded to a server.
How are teams balanced?
Names are assigned round-robin to each team in random order, so teams end up as equal in size as possible when the count divides evenly.
