Remote control for your VRChat avatar, and you set its limits.
The app runs on your PC. You pick the parameters and saved looks other people are allowed to change, and you get a link. They open it in a browser and the change lands on you a second later. Nothing else about your avatar is on that page.
Set your avatar up in VRChat the way you like it, then name the look.
Setup takes about a minute.
Run it
One executable. No installer, no admin rights. Turn OSC on in VRChat (Action Menu → Options → OSC → Enabled) and the app finds your avatar on its own.
Pick what they control
Share a handful of parameters, label each one, and set how far it can go. Everything else on the avatar stays out of reach.
Share the link
Send it to one friend or drop it in a group chat. Turn sharing off and the link dies. Make a new one and the old one never works again.
Other things it does.
The randomizer
One press rolls every toggle and slider on the avatar you're wearing. You can give viewers the button too, or keep it and roll it yourself with ⌘R.
Click the dice on a parameter and it stops getting rolled. That sticks to the avatar, so you only have to do it once.
Blocked namespaces
Anything under a blocked prefix never gets read. The app doesn't take the value in at all, so there's no way to share it by accident, roll it, or save it into a look.
FT/ and Go/ are blocked for everyone and can't be turned off. Add your own for anything you don't want the app seeing. It applies straight away.
Left out of looks
Names on this list get skipped when a look is saved. They also disappear from looks you saved before.
The movement pad
Turn it on and viewers get walking, turning and jumping. Held buttons release after three seconds. Taking control back turns it off.
The command palette
⌘K opens a search box for the whole app. Run any action or jump to any parameter without touching the mouse.
What someone with your link can't do.
None of these are settings. It's how the app is built, so there's nothing to get wrong.
Your PC has the final say
Only the parameters you shared leave your PC, and every command that comes back gets checked again here.
Nothing can connect in
The app doesn't open a port. It dials out to the relay, so there's nothing sitting on your machine waiting to be connected to, and nobody sees your IP.
Parameter names stay private
Your parameter list says plenty about your avatar on its own. People only see the labels you typed, and the relay is never told a name it has no use for.
Adult content gets blocked
Mark something adult and it's refused while safety mode is on. Their page says it's blocked, so it doesn't just look broken.
Stopping is one press
There is a stop button in the window and in the tray menu. The tray icon is green while anyone can control you and grey when nobody can. Quitting stops sharing first.
Start with two or three parameters.
Download it, share a couple of things, paste the link in your group chat. When you're done, press stop and every link goes dead.
