Cobalt is a web application designed to help users save various types of content from websites, including video, audio, photos, and GIFs. The application emphasizes privacy, security, and open-source principles.

Here are some of Cobalt's key features:

• Content Saving: Users can easily save desired content by simply pasting the link into Cobalt.

• Ad and Malware Protection: Cobalt is designed to protect users from ads, trackers, paywalls, and malware that may be present on other content-saving platforms.

• Privacy Focus:

  • All requests to Cobalt's backend are anonymous, and tunnel information is encrypted.

  • Cobalt maintains a strict zero-log policy, meaning they do not track user activity.

  • On-the-fly processing ensures that downloaded files are tunneled directly to the client without being saved to disk.

  • Users can enable forced tunneling to further enhance privacy by obscuring download sources from network providers.

• Open Community and Self-Hosting:

  • Cobalt fosters an active community of users who contribute to its development and improvement.

Cyd is a desktop application for macOS, Windows, and Linux designed to help users download and delete their data from X (formerly Twitter). The app functions by simulating human interaction with the X website, scrolling through pages and clicking buttons on the user's behalf. This method allows Cyd to bypass X's API, ensuring continued access to user data even if API access is restricted.

Here are some of Cyd's key features:

• Data Backup: Before deleting any data, Cyd can create a local, searchable backup of a user's X data, including HTML snapshots of their tweets.

• Tweet Deletion: Cyd offers flexible options for tweet deletion. Users can choose to delete all tweets or set parameters, such as deleting tweets older than a certain timeframe or those with less than a specified number of likes or retweets.

• Account Management: Cyd can help users who want to leave X while retaining their username. The app can delete all tweets and unfollow all accounts, leaving the account active but empty. This prevents others from taking over the username and allows users to leave a message directing followers to their new online presence.

• Likes and DM Deletion: Recognizing the potential privacy risks, Cyd can also delete a user's likes and direct messages.

Cyd prioritizes user privacy and security. The application runs directly on the user's computer, meaning neither Cyd's developers nor any third parties have access to the user's X account or data.

RSS Parrot is a service that turns your Mastodon account into an RSS feed reader. To use it, you mention @birb@rss-parrot.net in a toot with the URL of the site you want to follow. This could be a blog with a dedicated RSS or Atom feed, a website, a Substack newsletter, a Bluesky profile, or a podcast.

Here’s how it works:

• RSS Parrot finds the RSS feed for the website. If it’s the first time someone has requested this site, it creates a new Mastodon account dedicated to it.

• This new account posts a toot every time there is a new post in the website’s feed. The account’s name is based on the website address, with dots separating each letter, and hosted on the rss-parrot.net server. For example, the account for taiwantrailsandtales.com would be @taiwantrailsandtales.com@rss-parrot.net.

• You then follow the RSS Parrot account to see the new posts in your timeline.

This allows you to stay updated on your favorite websites without leaving Mastodon.

Toot is a command-line interface (CLI) and terminal user interface (TUI) tool for interacting with Mastodon instances. Toot allows users to post, reply, delete, and search for statuses on Mastodon. Users can also follow, mute, and block accounts, and upload media. The TUI supports image display in various terminal emulators like Kitty, iTerm2 and WezTerm. Toot is licensed under GPLv3.

MARL Utility and Features

MARL (Mastodon Archive Reader Lite) is a single-page app designed to help users explore the content of their Mastodon archive file. It offers a user-friendly way to view account data, posts, attachments, and more.

Here are some of MARL's functionalities:

• Direct Support for Archive Files: Users can simply drag and drop their archive file into the MARL window. The app unpacks the archive in the browser's memory without altering the original file or writing anything to the user's disk.

• Data Display: MARL displays various types of data from the archive, including basic profile information with pictures, full profile JSON data, posts with attachments, boosts, and full JSON data for each post or boost. It also provides an overview of hashtags, mentions, and users boosted in the user's posts.

• Filters: MARL offers numerous filters to help users refine their search within the archive. These include options to search full text or specific elements like hashtags, mentions, content warnings, or links. Users can also filter posts based on language, visibility, and the presence of media like images, videos, or sounds.

• Media Viewer: MARL allows users to view or play media attachments directly within the app, though there might be limitations based on file size, browser, and device capabilities.

• Accessibility: MARL prioritizes accessibility for all users, featuring optimizations for keyboard navigation, Forced Colors mode, and screen readers.

• Responsiveness: MARL is designed to function on various screen sizes, ensuring usability even on displays as small as 300 pixels wide.

While MARL offers comprehensive access to the Mastodon archive, it's important to note some limitations:

• Data Exclusions: The Mastodon archive file doesn't contain information about followed/follower accounts, blocked/muted accounts, user lists, or pinned posts. This information won't be displayed in MARL.

• Heavy Attachment Issues: Very large images or videos might fail to load in MARL due to browser/OS memory constraints. However, MARL provides the file path for each attachment within the archive, allowing users to access them directly.

• Limited Boost, Favorite, and Bookmark Data: Content originating from other Mastodon instances (boosted, liked, or bookmarked by the user) might not be fully included in the archive. This is due to instance-specific cache limitations, potentially leading to discrepancies between the displayed content and the user's Mastodon profile.

Overall, MARL provides a valuable tool for exploring and analyzing your Mastodon archive. However, it's crucial to be aware of the limitations and potential data gaps stemming from the archive file's structure and content.

Openvibe is described as a "town square for open social media" that aims to address the fragmentation of decentralized social networks. Traditional social media platforms have faced numerous issues, including data privacy concerns, censorship, and the spread of misinformation. As a result, many users have migrated to decentralized platforms like Mastodon, Bluesky, Nostr, and Threads. However, these platforms are isolated from each other, creating division and making it difficult to connect with friends across different networks.

Openvibe offers a solution by aggregating all decentralized networks into a single timeline. Its key features include:

• Connecting across open social media: Openvibe enables users to reach friends on any decentralized network.

• Following ideas, not protocols: Users can engage with content based on their interests rather than being limited by platform boundaries.

• Cross-posting: Openvibe allows users to simultaneously share content across multiple platforms.

• Floating identity: Users can maintain a consistent social presence across different networks.

• Gain control: Openvibe offers an ad-free and data-selling-free experience.

• User friendly and permissionless: Openvibe is designed to be accessible and open to all.
