Gitmask

Contribute Code Anonymously

Introduction

Gitmask is an open source hosted service that allows you to contribute to Github projects anonymously. It mimics a standard git remote, however all identifying information (author names, email and timestamps) embedded in your commits are stripped, before forwarding a squashed commit to the target repository as a pull request.

Features

• Does not require a Github account - Gitmask is completely anonymous
• Mimic's a standard git remote, allowing you to keep your normal development workflow and tools.
• Automatically creates a pull request against target repository & branch
• Hosted Open Source project. Use gitmask.com or run it yourself if you're privacy conscious.
• Inline progress logs
• Coming Soon Allows you to anonymously comment on Pull Requests opened by Gitmask, to provide context to your commits.

Why?

There's a number of reasons why you may want to contribute to a Github project anonymously.

• Government - you may live in a country/region where the government tracks your contributions online
• Career - you may be contributing to a project that your employer may not approve of
• Security - you may want to contribute to a project that implies financial interest
• Prove a point - you may want to write something controversial to start a discussion.
• You just value your privacy.

Getting Started

git clone https://github.com/AnalogJ/gitmask.git
git checkout -b feat_branch
echo "update readme" >> README.md
git commit -am "Commits will be squashed and messages overwritten"
git remote add gitmask https://git.gitmask/v1/gh/AnalogJ/gitmask
git push gitmask feat_branch:master

# Gitmask will strip identifying information from your commits.
# You will be provided with a direct link to the pull request.
