Control OBS Studio from your phone

OBS Blade talks to OBS Studio through the OBS WebSocket v5 interface that ships inside OBS itself. Your phone connects straight to your PC over your local network - there's no account, no cloud relay and nothing to install on the PC beyond OBS 28 or newer. Everything below works the same on iPhone, iPad and Android.

What you need

• OBS Studio 28 or later. WebSocket v5 has been built in since OBS 28, so there's no plugin to install. Check Help → About if you're not sure which version you run.
• A phone or tablet on the same Wi-Fi or LAN as the PC running OBS.
• OBS Blade from the App Store or Google Play. Free - every OBS control is in the free tier.

Connect in three steps

1. Turn on the WebSocket server in OBS.

   In OBS, open Tools → WebSocket Server Settings. Tick Enable WebSocket server, leave the port at the default 4455, and set a password. You'll enter it in the app once, so pick something you can type on a phone keyboard.

2. Put your phone on the same network.

   Your phone or tablet needs to reach the PC over Wi-Fi or LAN. Guest Wi-Fi networks and some routers isolate devices from each other - if yours does, use the main network instead (more on that below).

3. Connect from OBS Blade.

   Open OBS Blade and add a connection. The app discovers OBS on your network by itself in most setups. If it doesn't show up, enter the connection manually: your PC's local IP address, port 4455, and the password from step 1. On Windows you'll find the IP with ipconfig; on macOS under System Settings → Wi-Fi.

That's it - the dashboard comes up live, and OBS Blade will remember the connection and reconnect on its own next time.

What you can do from your phone

• Switch scenes (with studio mode and your transitions) and watch a live preview of what your viewers see.
• Start, stop and pause your stream, recording, replay buffer and virtual camera.
• Mix audio with live volume meters for every input, and mute anything in one tap.
• Show and hide sources in any scene - the overlay, the webcam, the game capture - and control media playing in the scene.
• Watch stream health as it happens: FPS, CPU, memory, bitrate and dropped frames, with a saved history of every session.
• Read and answer chat for Twitch, YouTube, Kick and Owncast, in its own tab or next to your controls while you're live. Native, combined multi-platform chat with full moderation is part of OBS Blade Pro.
• Swap profiles, scene collections and fire hotkeys without touching the keyboard.

Troubleshooting: when it won't connect

Almost every connection problem is one of these five:

• Not actually the same network. The phone is on guest Wi-Fi, a different SSID band with client isolation, or mobile data. Many routers offer "AP isolation" / "client isolation" - turn it off for the network your streaming gear uses.
• A firewall is blocking port 4455. Windows may have asked when OBS first opened the server; if you declined, allow OBS through the firewall for private networks. Third-party firewalls need the same rule.
• Wrong password. The password lives in Tools → WebSocket Server Settings, not in your OBS profile or your streaming account. Re-check it character by character.
• OBS is older than 28. The built-in server only exists from OBS 28 on. Updating OBS is the fix - don't install the old third-party websocket plugin alongside it.
• A VPN on the phone. A VPN route can make your LAN unreachable. Pause it while you connect locally.

Going further

Once the basic connection works, two natural next steps: put a tablet on your desk as a always-on stream deck, or reach OBS from outside your home network - safely, without exposing the WebSocket port to the internet.
