Lienol's Modified OpenWrt source
A community fork of OpenWrt, the Linux-based router operating system that replaces your router's factory firmware with a fully customizable system where you install only the software you need.
This repository is a modified fork of OpenWrt, a Linux-based operating system designed to run on home routers and other small embedded network devices. OpenWrt replaces the factory software that ships on a router with a fully customizable system where you can install, remove, and configure software packages yourself, rather than being stuck with whatever the manufacturer decided to include.
The practical effect is that a router running OpenWrt can do far more than a typical home router: ad blocking, VPN routing, traffic monitoring, mesh networking, and many other functions that require nothing more than installing additional packages. The underlying idea is that the device is a small Linux computer, and you can treat it that way.
This particular repository is a modified version maintained by the GitHub user Lienol. The README does not describe what specific changes or additions Lienol has made compared to the upstream OpenWrt project, so it is not possible to say from the available information what sets this fork apart.
Building a custom firmware from this source requires a Linux, BSD, or macOS computer with a case-sensitive file system, along with a set of standard development tools. The build process downloads all source packages, compiles a cross-compile toolchain, and then produces firmware images suitable for a specific target device. Pre-built firmware images for many common routers are also available through the main OpenWrt project's firmware selector, though those come from the upstream project rather than this fork.
The codebase is licensed under GPL-2.0.
Where it fits
- Replace a home router's stock firmware with a custom OpenWrt build that includes an ad blocker and VPN client.
- Set up a mesh network across multiple routers in a large home or office using OpenWrt's package system.
- Monitor and shape network traffic on a router without buying a dedicated hardware appliance.
- Build a custom firmware image for a specific router model with only the packages your use case needs, reducing attack surface.
