Rostara is the home base for your weekly game. Rate your players, split them into even teams, sort out who's coming, handle the money, and run tournaments. All in one place.
Free to use · Works in any browser, on phone or laptop
Your group rates each other on the skills that matter, and it stays private, so nobody sees who gave what. At game time, Rostara splits everyone into even sides in one tap and tells you how close the match really is.
Post a game, pick when RSVPs open, and watch the list fill up. Waitlists, guest spots, and calendar links are built in, so you're done counting heads in the group chat.
Keep the group pot and everyone's balance in one place. Members log what they paid, an admin signs it off, and you close out the season with numbers everyone trusts.
Set up a round-robin, a knockout, or a league followed by a knockout. Rostara draws the fixtures, and the table updates itself as you enter each result.
Everything below is the real thing — no mockups.

Post announcements with reactions so the important stuff doesn't scroll away.
Get a nudge when a game goes live, RSVPs are closing, or a payment needs sign-off. Turn off any you don't want.
Start from a Soccer, Basketball, or Volleyball preset, or build your own skill list.
Yes. Creating a group, rating players, balancing teams, running RSVPs, keeping the ledger and running tournaments are all free. There are no ads, and Rostara never handles your money — the ledger is a record of what your group agreed, not a payment processor.
No. Individual ratings are private. Everyone sees the group average for a player, but never who gave which score — that's what keeps people honest and keeps the teams fair.
No. You can add players as names only and still rate them, put them on teams and count them in RSVPs. They can claim their spot with an account later if they want to RSVP themselves.
Any sport where you split into sides. Soccer, futsal, basketball and volleyball come with ready-made skill presets, and you can write your own list of skills for anything else.
Twelve: Arabic, German, English, Spanish, Persian, French, Indonesian, Italian, Japanese, Korean, Portuguese and Turkish. Rostara follows your phone's language by default, and you can pick a different one at any time without touching your device settings.
No — Rostara runs in your browser on any device. You can also add it to your phone's home screen so it opens like a normal app.
You share one invite link. Anyone who opens it lands straight in your group, so there's nothing to set up on their side.
Make a group, share the invite link, and you'll be running your next game in minutes.
