Clear OBS Browser Cache Without Losing Scenes

This article provides a quick and direct guide on how to completely purge cached browser source cookies, login sessions, and local storage data within OBS Studio. Following these steps will resolve broken web widgets, outdated overlays, and login errors while keeping your custom scenes, sources, and profile layouts completely intact.

Step-by-step Guide to Purging OBS Browser Cache

To completely clear all cached cookies and data from your OBS browser sources without affecting your scene layouts, you must delete the dedicated browser plugin configuration folder.

Step 1: Close OBS Studio

Before modifying any files, ensure that OBS Studio is completely closed. If the program is running in the background, file locks will prevent you from clearing the cache successfully.

Step 2: Navigate to the OBS AppData Folder

OBS Studio stores its browser plugin data separately from your scene layouts.

  1. Press the Windows Key + R on your keyboard to open the Run dialog box.
  2. Type %APPDATA%\obs-studio\plugin_config and press Enter.
  3. A File Explorer window will open directly to the OBS plugin configuration folder.

(Note for Mac users: Navigate to ~/Library/Application Support/obs-studio/plugin_config/ using Finder’s “Go to Folder” option.)

Step 3: Delete the Browser Cache Folder

  1. Inside the plugin_config folder, locate the folder named obs-browser.
  2. To completely purge all cookies, session states, local storage, and cached files, delete the entire obs-browser folder.

Deleting this folder is completely safe. OBS Studio will automatically recreate a fresh, clean version of this folder the next time you launch the software. Because your scene layouts and configurations are stored in the basic folder rather than plugin_config, your scenes will remain untouched.

Step 4: Relaunch OBS Studio

Open OBS Studio again. All of your browser sources will reload from scratch.

Note: Since this process deletes all cookies and local session data, you will need to re-authenticate or log back into any interactive web overlays, chat widgets, or stream alerts that require a login.
