NoSteamWebHelper

A program that disables Steam's CEF/Chromium Embedded Framework.

Aim

This program was created with the intent of replacing of Steam's command-line parameter -no-browser which was removed.

How does NoSteamWebHelper kill or disable the CEF/Chromium Embedded Framework?

• The executable does the following:
  • Launches Steam with the following arguments -cef-single-process -cef-disable-breakpad -cef-disable-gpu-compositing and appends any user provided ones, this restricts the CEF to a single process.
  • Injects the dynamic link library.

The dynamic link library toggles the CEF depending if an is app running or not.

• If an app is running then the CEF is disabled.
• If an app is not running then the CEF is enabled.

[!NOTE] You may also manually toggle the CEF via a tray icon provided by NoSteamWebHelper.

This way, the Steam UI is still accessible to use.

2. Unzip NoSteamWebHelper.zip, place NoSteamWebHelper.exe & NoSteamWebHelper.dll in your Steam installation directory where steam.exe is located.

3. Make sure Steam is fully closed and run NoSteamWebHelper.exe to launch Steam.
