Fedilab is a versatile and feature-rich mobile application designed to provide users with a seamless experience for accessing and interacting with decentralized social networks. Developed by Thomas Meunier, Fedilab is available for Android devices and serves as a one-stop solution for connecting with various federated social networks, including Mastodon, Pleroma, Peertube, GNU Social, and many others.

The term "Fediverse" refers to a network of interconnected social media platforms, each using a different server but allowing users to interact with one another across platforms. Fedilab is tailored to embrace this decentralized structure and enables users to manage multiple accounts across various federated networks from a single app.

Key features of Fedilab include:

Multi-Account Support: Fedilab allows users to add and manage multiple accounts from different federated networks. This means you can access content and interact with users on platforms like Mastodon, Pleroma, Peertube, and more, all within one app.

Timeline Customization: Users can customize their timelines, filter content based on keywords, mute or block users, and sort posts based on various criteria, ensuring a personalized social media experience.

Interactivity and Posting: Fedilab supports various types of media uploads, including images, videos, and links. You can post across multiple accounts simultaneously and engage with other users' content through likes, comments, and boosts (reposts).

Notifications: The app keeps you informed about new interactions, mentions, and messages from across all your federated accounts, providing a unified notification system.

Privacy and Security: Fedilab prioritizes user privacy and offers various privacy settings, such as the ability to disable tracking and prevent unwanted data collection. Additionally, the app allows for secure access to instances through HTTP signatures and two-factor authentication (2FA).

Seamless Browsing: Fedilab incorporates a built-in web browser, allowing you to view external links without leaving the app.

Cross-Platform Sharing: You can share content from other apps directly to Fedilab, making it easier to share your thoughts and experiences with your followers on federated networks.

Open Source: Fedilab is an open-source project, meaning the app's source code is publicly available for review and contributions from the community.

Fedilab has gained popularity among users who appreciate its user-friendly interface, customization options, and support for multiple federated networks, making it a popular choice for those looking to explore and engage with the decentralized social media landscape.
