Kwrt

Kwrt is a custom router firmware generator and build system designed to compile personalized network hardware images and Linux-based router operating systems. It specifically serves as an OpenWrt firmware builder and image customizer, allowing for the creation of tailored operating systems based on specific software packages, kernel configurations, and hardware targets.

The system produces firmware in multiple boot formats, including EFI, Legacy, virtual disk files, and root archives for containers. It enables the generation of specialized images for x86 or virtualized network hardware, providing a mechanism to define hardware interface configurations and network port assignments before deployment.

The build process covers several optimization areas, including software footprint reduction through package selection, system performance tuning via kernel and file system selection, and the integration of custom visual themes for the web management console. It also handles initial network provisioning for hostnames and gateways, as well as static partition mapping for external storage.

Features

OpenWrt Customizations - Provides a comprehensive build system for creating custom OpenWrt firmware images with tailored packages and kernel configurations.

Firmware Image Build Orchestrators - Orchestrates the cross-compilation of entire firmware images including the kernel, drivers, and userland tools.

Network OS Compilers - Provides a build environment specifically designed to produce customizable operating systems for networking hardware.

Firmware Generators - Compiles declarative configuration files into optimized binary firmware images for network hardware.

Custom Kernel Compilation - Builds the operating system kernel from source to optimize hardware performance and file system types.

Package Selection - Provides build-time selection of software packages and plugins to minimize the final firmware image size.

Multi-Format Disk Image Generation - Produces firmware in various formats, including EFI, Legacy, virtual disk files, and root archives for containers.

Boot Image Generation - Produces complete bootable OS images in formats such as EFI or Legacy tailored for target hardware.

Firmware Image Generators - Packages compiled code into binary images formatted for direct writing to network hardware flash.

Embedded Network Device Management - Manages the software and configuration of embedded networking hardware before the image is flashed.

Firmware Size Optimization - Reduces the memory and storage footprint of firmware by excluding unnecessary features and tuning the kernel.

Soft Router Images - Creates specialized firmware images for x86 or virtualized network hardware to act as a primary router.

Static Partition Mapping - Assigns external storage partitions to system directories during the build to expand available disk capacity.

OS Kernel Tuning - Supports selecting specific kernel versions and file system types to optimize performance for hardware or virtual environments.

Binary Footprint Optimizers - Prunes unnecessary application packages and plugins during the build to reduce the total system footprint.

Network Interface Configurations - Enables the definition of network port assignments and interface configurations within the firmware.

Network Provisioning - Enables the embedding of default hostnames, subnet masks, and gateway addresses directly into the firmware image.

Network Provisioning Parameters - Embeds default hostnames, gateways, and subnet masks directly into the firmware image before deployment.
