Key features:

• Filtering: Users can filter accounts by categories such as "Best", "Popular", "Human", "Project", and "Recently posted". There are also filters by programming language, such as Python, Rust and JavaScript. Frameworks, libraries, and other categories like "Open Source", "Linux", "Security", and "React" can also be used to filter accounts.

• Sorting: Accounts can be sorted by followers, following, posts, date of last post, and time since last post (last day, last 7 days, last 30 days or all time).

• Search: The application allows users to search by name, bio, or instance.

• Account Information: For each account, the application displays the username, bio, last post date, number of posts, follower count, following count, and a link to the account's Mastodon page.

• Mastodon Integration: It requests write permissions to follow accounts directly from the app.

The listed accounts cover a wide variety of topics, especially in the tech and security fields. Many accounts listed are related to open source software, Linux, security, and privacy. There are also accounts related to law, civil liberties, and politics. Some notable accounts include the European Commission, cybersecurity experts, journalists, and open-source projects.
