How AdGuard uses GitHub to stay transparent and user-oriented

At AdGuard, we fight daily to make the Internet safer, more comfortable, and more transparent. This commitment is reflected not only in our product features and strict privacy policies, but also in the fact that we keep our work as open as possible. That includes actively interacting with our community.

This is why all of our products have public repositories — online spaces where anybody can see what we are working on, report issues directly to AdGuard developers, and even contribute to our open-source projects. The repositories cover our ad-blocking apps, filters, browser extensions, DNS solutions, VPN tools, developer utilities, and more. There are different platforms that offer such functionality, but the most popular one by far is GutHub, and all AdGuard projects are stored there.

This article lists the most important repositories by category, summarizes the purpose of each one, and gives a simple breakdown of what users can do there.

What is Github and its repositories

Very simply put, you can think of GitHub as sort of Google Docs for code, where multiple people can work on the same project, track changes, and see who made which updates. It provides a central, cloud-based place to store your code so it’s accessible from anywhere. It also has teamwork tools for reviewing changes, fixing issues, and merging everyone’s work smoothly.

GitHub is widely used for open-source projects, letting anyone view the code, suggest improvements, and contribute.

A repository (often called “repo” for short) is the most basic element of GitHub. It's a place where you can store your code, your files, and each file's revision history. Repositories can have multiple collaborators and can be either public or private.

Where to start

You can find links to key repositories below in this article or visit the general AdGuardTeam GitHub page for a full list. In most repos, you can:

• View README file on the main page: it gives you an introduction to the product and its repo
  

• Check existing bug reports or feature requests, comment and upvote
  

• Create issues to report bugs or request features
  

• Check releases for different versions and their changelogs (and install an older version if needed)
  

• Install any older or beta version if needed
  

Note: If you are new to GitHub, you’ll need to create a GitHub account in order to create new issues and comment on the existing ones.

In open-source repos advanced users can also:

• Browse code to understand product logic, what technologies are used and how they are implemented
• Fork and contribute via pull requests

Whether you’re a casual user, technical expert, or a developer, AdGuard welcomes all community participation across its GitHub repos.

Legal documents

As part of our commitment to transparency, we host all legal documents — such as End-User License Agreements, Privacy Policies, and Terms and Conditions — on GitHub. Our LegalDocs repo lets anyone check the full history of changes to these documents.
