Friend Compatibility Test
Question-based friendship chemistry for entertainment
Check our friendship chemistry →Free · No signup · Instant results
You and a friend answer short Likert questions. Fixed weights are applied to the answer differences to produce an entertainment chemistry score.
Everything runs in your browser. Optional birthdays are used only for fun labels, with a legacy hash fallback when questionnaire data is unavailable. Treat the score as a conversation starter, not a verdict.
Is the friend compatibility test free?
Yes — completely free, no signup or credit card required.
Does it work for friends, or only couples?
The engine compares two sets of answers, so it works for friends, coworkers, siblings, or couples as entertainment.
Will our birthdays be saved?
No. All processing happens in your browser. Neither birthday is sent to our servers or shared with third parties; entries stay on your device.
