OBS Studio

Connect KATTTIK Stream Studio to OBS Studio for automated scene switching and source control

OBS Studio is the ultimate open-source software for video recording and live streaming. KATTTIK integrates with OBS to automate scene switching, source control, and production.

What Can KATTTIK Do with OBS?

With OBS integration, KATTTIK can:

Switch scenes automatically (e.g., gift ? switch to celebration scene)

This turns viewer interactions into production automation.

Prerequisites

OBS Studio installed (latest version recommended)
OBS WebSocket enabled (built-in since OBS 28+)
Both KATTTIK and OBS running on same PC or network

How to Enable OBS WebSocket

Open OBS Studio ? Tools ? WebSocket Server Settings

Check Enable WebSocket server

Port: default 4455 (or 4444 for old versions)
Enable Authentication: Recommended, set password
Note the port and password

Click OK and restart OBS if needed

How to Connect KATTTIK to OBS

In KATTTIK Stream Studio ? Go to Integration ? OBS Studio

Enter OBS WebSocket details:

Host: localhost or 127.0.0.1 (if same PC)
Port: 4455 (or your custom port)
Password: Your WebSocket password (if set)

Click Connect ? Should show Connected

Test: Create Action ? OBS Action ? Switch Scene ? Select scene ? Test button should switch scene in OBS

If KATTTIK runs in browser and OBS on same PC, use localhost. If using Windows Toolkit, it can bridge connection more reliably.

Best Practices

Name scenes/sources clearly: No spaces special chars issues - use simple names
Test offline: Test all OBS actions before live
Use delays: Chain actions with delays for sequences
Backup OBS: Export OBS profile and scene collection
Keep WebSocket secure: Use password, don't expose port to internet
Check OBS logs: If action fails, check OBS logs for WebSocket errors

Troubleshooting

Can't connect?
- Check OBS WebSocket enabled and port correct
- Check firewall not blocking port 4455
- Try 127.0.0.1 instead of localhost
- Ensure OBS running
Action not working?
- Check scene/source name exact match (case sensitive)
- Check OBS WebSocket version compatibility (OBS 28+ uses 5.x protocol)
- Test with simple action first
Delay/lag?
- Normal 100-300ms delay for WebSocket
- Keep PC performance good, close heavy apps
