Synastry

Synastry is free, non-commercial hobby software created with the assistance of AI. I make no apology for using modern tools to turn weeks/months of development into days and make this project possible.

Because handholding is the most important mechanic to sync.

Synastry makes group animations easy. Create a room, invite your friends, pick an animation, choose who does what, and wait until everyone is ready, then start together.

It can tell who already has the animation, securely offer it to anyone missing it, line everyone up, and keep the timing synchronized. No digging through endless mod lists. No shouting “ready?” five times. No discovering halfway through that someone chose the wrong role.

Perfect for dances, screenshots, roleplay, and serious "Extreme Raid Progression", obviously.

Synastry is not intended for exchanging paid animations or other content you do not have permission to share. Please support the talented creators in this community whenever you can—they invest real time, energy, and creativity into making these fun experiences possible.
