Random Boolean Generator produces random two-state values in your preferred format: `true / false`, `yes / no`, `heads / tails`, `1 / 0`, or `on / off`.

Handy for coin flips, decision prompts, test fixtures, and seeding toggle states in demo apps.

Why use it

Run a virtual coin flip.
Make quick yes/no decisions.
Seed toggle-state demos.
Fixture boolean columns in databases.
Prompt A/B user interviews.
