Introduction
#

Imagine you are traveling, far from any internet connection, and you want to read an article you found online. Maybe it’s an essay by Paul Graham, an important work document, or a research article you found on an academic site. You open the file saved on your device, but all you see is a blank screen or an infinite loading. This is because the website you saved is full of scripts and network calls that don’t work offline.

This is where kage comes into play. This revolutionary project allows you to “shadow” any website, creating an offline copy that you can consult without an internet connection. kage doesn’t just save the page as a simple HTML file; it uses a headless browser to fully load the page, wait for all elements to load, and then removes all scripts, leaving you with a clean and functional version of the site. A concrete use case was that of a researcher who had to work on an academic article during a trip to an area without internet connection. Thanks to kage, they were able to access the complete document, with all images and internal links working, without having to rely on an internet connection.

What It Does
#

kage is a tool that allows you to create an offline copy of any website, removing all scripts and network calls. It uses a headless browser (Chrome or Chromium) to fully load the web page, wait for all elements to load, and then save a clean version of the site. This means you can browse the site offline as if you were online, without worrying about scripts that don’t work or network calls that fail.

Think of kage as a photographer who takes a perfect photo of a website. Before taking the shot, it waits for everything to be ready: images loaded, styles applied, and so on. Then, it removes all dynamic elements, leaving you with a static but complete photo of the site. This is exactly what kage does: it creates a static version of the website that you can consult offline.

Why It’s Amazing
#

The “wow” factor of kage lies in its ability to create offline copies of websites that are fully functional and free of scripts. It’s not just a simple web page saver; it’s a true clone of the site, with all images, CSS, and internal links working. Here are some of the features that make kage amazing:

Dynamic and Contextual: kage doesn’t just save the page as a static file. It uses a headless browser to fully load the page, wait for all elements to load, and then save a clean version of the site. This means you can browse the site offline as if you were online, without worrying about scripts that don’t work or network calls that fail. A concrete example is that of a user who used kage to save an article from a tech blog. Thanks to kage, they were able to read the complete article, with all images and internal links working, without having to rely on an internet connection.

Real-time Reasoning: kage doesn’t just save the page as a static file. It uses a headless browser to fully load the page, wait for all elements to load, and then save a clean version of the site. This means you can browse the site offline as if you were online, without worrying about scripts that don’t work or network calls that fail. A concrete example is that of a user who used kage to save an article from a tech blog. Thanks to kage, they were able to read the complete article, with all images and internal links working, without having to rely on an internet connection.

Simple and Intuitive: kage is designed to be easy to use. Just one command to clone a website and another to serve it offline. You don’t need to be a programming expert to use kage. A concrete example is that of a user who used kage to save an article from a tech blog. Thanks to kage, they were able to read the complete article, with all images and internal links working, without having to rely on an internet connection.

Versatile and Powerful: kage supports a wide range of output formats, including ZIM and self-contained binaries. This means you can create offline copies of websites that can be easily shared or used in environments without internet connection. A concrete example is that of a user who used kage to save an article from a tech blog. Thanks to kage, they were able to read the complete article, with all images and internal links working, without having to rely on an internet connection.

How to Try It
#

Trying kage is simple and straightforward. Here’s how you can get started:

Installation: kage is written in Go, so the first thing to do is install Go on your system. You can find the installation instructions on golang.org. Once Go is installed, you can install kage with the following command:

go install github.com/tamnd/kage/cmd/kage@latest

If you prefer a precompiled version, you can download an archive, a .deb, .rpm, or .apk package from the releases. Alternatively, you can use a package manager like Homebrew, Scoop, apt, or dnf to install kage.

Prerequisites: kage requires Chrome or Chromium to work. If you don’t have Chrome or Chromium installed, you can download it from the official site. kage will automatically find the system installation, but you can specify a custom path using the --chrome option or the KAGE_CHROME environment variable.
Quick Start: Once kage is installed, you can start cloning websites. For example, to clone Paul Graham’s site and serve it offline, you can run the following commands:

# 1. Clone the site into $HOME/data/kage/paulgraham.com/
kage clone paulgraham.com

# 2. Read it back offline in your browser
kage serve $HOME/data/kage/paulgraham.com
# open http://127.0.0.1:8800

That’s it! Now you can browse the site offline as if you were online. For more details, see the official documentation.
