What is alias-cockpit?

Alias Cockpit is a Windows desktop application for generating and managing email aliases, meaning variations of your Gmail or Outlook address like adding dots or a plus sign and tag, so you can give a slightly different address to each website or service while it still lands in your one real inbox. Everything runs and is stored locally on your own computer rather than in the cloud, which the project calls being local first. The main screen lets you type in a Gmail or Outlook address, add tags describing where you plan to use each alias, and generate a batch of alias candidates. It supports Gmail's dot trick and the plus-tag trick where each service supports them, and it disables the dot option automatically for addresses that do not support it. You can then mark each generated alias with a site name, purpose, and color label, filter the list to see marked or unmarked ones, and copy whichever alias or list of aliases you need. Saved addresses and alias history are kept so you do not have to retype the same information each time. Behind that main screen, the project also includes the underlying building blocks: alias generation logic, a way to estimate how guessable an alias is, import and export through CSV files with a safe dry run mode, an audit trail of actions taken, and local storage using SQLite, a lightweight embedded database. Sensitive information like provider account secrets, if used at all, is stored through Windows' own Credential Manager rather than in the plain local database. The README is explicit that features like encrypted syncing across devices, full automatic syncing with email providers, and complete automated interface testing are not finished yet, and that the app does not contact real email provider services during normal everyday use. To run it, you need a fairly recent version of Windows 10 or newer, plus a .NET SDK and runtime that the project expects you to install yourself since it is not bundled in a fresh download. The repository also includes scripts to build test files, format the code, and package the finished application into a portable ZIP file, a Windows installer package, or a standalone setup program, along with automated release publishing to GitHub. This tool would suit privacy conscious Windows users who want fine grained control over the email aliases they hand out to different websites, without relying on a third-party cloud service to manage them.
