Fair groups with balance, constraints, and fewer repeats

GroupMixer creates random, balanced, and constraint-aware groups for classrooms, workshops, conferences, and networking events. Its standout is a world-class Social Golfer solver that finds exceptionally low-repeat schedules across multiple rounds while respecting group sizes and practical rules. The main workflow runs locally in your browser, is free, and requires no account.
Ran it for a small workshop and the Social Golfer scheduler handled our uneven team sizes without a fuss. Loved that nothing left my browser, though the results screen could use a quick export to csv.
ran a quick test for a workshop i help run and honestly the social golfer solver is the real deal, basically zero repeats across 5 rounds. love that it all runs in the browser too.
A social golfer solver that runs entirely in the browser is genuinely impressive. One thing that would make this even more useful for conferences: letting organizers weight certain participants to stay apart or together (for example, keeping a presenter away from their co-presenter), and surfacing a quick rationale for why the schedule looks the way it does.
