SLBr

A lightweight browser for a faster web
Fast, lightweight browsing with a clean interface.

SLBr

SLBr is an open-source, lightweight web browser based on Chromium. Built with .NET, WPF, and CefSharp (CEF) to provide a modern browsing experience while remaining lightweight.

Using CefSharp

CefSharp is a .NET wrapper for the Chromium Embedded Framework (CEF), providing an embedded Chromium browser for WPF and WinForms applications. It supports modern web standards, including HTML5, JavaScript, CSS3, WebGL, and HTML5 audio/video.

Missing class SECRETS

The SECRETS file is removed as private API keys are stored inside. To fix it, either:

• Remove the code that is causing the error, which will remove the ability to use Google Safe Browsing & sign in to Google.
• Generate a new C# class called "SECRETS":

namespace SLBr
{
    class SECRETS
    {
        public static string GOOGLE_API_KEY = "";
        public static string GOOGLE_DEFAULT_CLIENT_ID = "";
        public static string GOOGLE_DEFAULT_CLIENT_SECRET = "";
        public static string DISCORD_WEBHOOK = "";
    }
}
