Open Source & Free Tools for Web Workers

Features:

• Customizable CSS property prefixes. For example, the prefix for "display" can be changed from "dis" to "d".

• Optional custom value names. For instance, the value "flex" can be associated with the custom name "fx".

• Selective addition of !important keyword utility classes. By setting generate_utility to true, utility classes with !important can be generated for each CSS property.

• Responsive design on-demand. Users can set screen sizes and apply CSS properties selectively for each size. Responsive settings are defined in the screenSizes object. The responsive property can be set to true or false for each CSS property.

• Use of tokens. Tokens are lists of names associated with values, organized by families, and reusable. Tokens prevent repeating the same names and values across multiple CSS properties. Each token is written as a CSS variable.

• CSS variables that are automatically generated.

• Automatic documentation of the CSS output. An interactive documentation is generated automatically.

• Instant file size impact of the settings.

• Offline functionality.

To get started, users need to download the starter project, edit the build.json file, and run it through a browser. The tool requires only a text editor, a web server, and a browser. The JSON settings include:

• separator: A string to split names, values, and utility prefixes.

• responsiveSeparator: A string to split screen size names.

• utilitiesPrefix: A string for utility classes.

• cssVariablesPrefix: A string used for tokens' CSS variables.

• screenSizes: An object that defines screen sizes.

The JSON tokens are lists of names associated with values, organized by families. Tokens are optional and can be left empty if unused.

The JSON properties object has keys that are valid CSS property names. Each CSS property has a prefix, generate_from to refer to a token, a list of values, an optional list of names, responsive which is a boolean, and a generate_utility boolean to generate utility classes.

Features:

• Multiple Cursors: It allows you to share your screen with anyone and collaborate with multiple cursors. You can also use a ping feature to mark important areas with your remote cursor.

• Zero Configuration: The service requires no sign-up, login, or account creation. It generates a unique connection URL that you can share.

• Privacy First: Your data is never stored on any server, as it establishes a direct connection between you and the person you're sharing with. It uses WebRTC technology for a secure connection.

• Connection URLs: Bananas creates a unique URL for sharing your screen, but these URLs should be treated as sensitive information. The URL must be shared via another communication channel because there are no servers involved, except those needed for the initial connection.

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.
