Open Source & Free Tools for Web Workers

Firecamp is a platform designed to help developers build APIs faster by providing a comprehensive set of tools for testing and collaboration.

Features:

• Multi-protocol Support: Firecamp offers a dedicated playground for various protocols, making it a multi-protocol platform.

• API Playgrounds: It provides instant playgrounds for testing APIs, including REST and GraphQL.

• API Collections: Firecamp allows users to manage collections of APIs for team collaboration.

• Team Collaboration: The platform enables real-time team syncing, facilitating easier collaboration. It allows users to share endpoint details and socket events directly with their team without special documentation.

• API Documentation: Firecamp can be used to publish API documentation.

• API Test Runner: It allows users to visually run API collections within the platform.

• CLI & CI/CD: API collection tests can be run in the terminal or set up in a CI/CD pipeline.

• Variables: The platform allows setting values in variables to be reused dynamically throughout the platform.

• Web & Desktop Apps: Firecamp is available as both web and desktop applications.

• Authentication: It supports testing and debugging of authentication endpoints with a range of authentication methods.

• GraphQL Support: Firecamp provides features specifically for GraphQL, such as retrieving endpoint schemas with a button click and a GraphQL query builder.

• All-in-One Solution: It aims to be an all-in-one solution, eliminating the need for multiple tools for different types of API testing. By combining different functionalities, Firecamp removes the need to download and manage several different tools, hold different subscriptions, and file issues on different projects.

• Efficiency: Firecamp enhances developer productivity by streamlining API testing workflows.

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.

Termo is a simple terminal emulator for the browser that allows you to create a terminal-like interface on a website. It is a wrapper on top of xterm.js.

Key features include:

• Customizable appearance: You can set the terminal's title, prompt, font, and theme.

• Welcome message: A message can be displayed when the terminal opens.

• Command execution: You can add and execute JavaScript commands.

• Sound effects: Control terminal sound effects.

• Full access to xterm.js: You can access the underlying xterm.js library.

• Docking/floating mode: The terminal can be set to docked or floating mode.

Termo can be installed via CDN or npm. It offers methods to create, show, hide, set the theme, destroy, dock, and float the terminal. It accepts an object with configuration options like playSound, title, welcomeMessage, theme, fontFamily, prompt, commands, and terminalOptions. You can define custom commands with a name, description, action and optional subcommands.

Feber is a simple and free, self-hostable group calendar application. It is a single PHP file with assets that can run on almost any web host. Feber is database-free and file-based, making it easy to set up, backup, and transfer.

Feber's key features include:

• Event booking and easy repetition of events.

• Four user permission levels ranging from read-only to admin.

• Anonymous viewing/editing link option.

• ICS/ICAL subscription link option.

• Automatic dark/light theme.

• Customizable calendar title and Monday/Sunday week start.

• Localization - currently available in Danish, English, French, German, and Turkish.

Feber focuses on a limited set of features, aiming for simplicity and ease of use. For example, it does not offer CalDAV, multiple calendars per installation, native multi-day booking, or away times. You can install Feber by uploading its files to a directory on your web host and completing the setup form. Backups are created by downloading all files from the directory. Feber can be updated by dragging newer version files onto the existing directory.

A potential issue is that some web hosts have aggressive caching that may prevent PHP scripts from executing. If this happens, you may need to disable or adjust the caching settings or contact your web host's support.

Electrobun is a framework for building desktop applications using Typescript. Some of its key features and benefits include:

• Typescript: Use Typescript for both the main process and webviews.

• Speed: Electrobun prioritizes fast build times to enable rapid iteration on features and fixes. It also allows for small and cost-effective updates, enabling frequent shipping of new features and fixes to end users.

• Batteries included: Electrobun aims to provide everything you need to build, test, code-sign, and update your application in a single, integrated workflow.

• Affordability: Electrobun is MIT open-source and only requires a file server to distribute the application, making it affordable to maintain.

• Flexibility: Electrobun allows you to use any modern framework for the user interface, including plain HTML, Preact, and SolidJS. It uses the built-in system webview and will support bundling third-party webviews like Chromium in the future.

• Security and Performance: Built on Bun and Zig, Electrobun isolates the main process and browser processes. It provides optional, fast, typed, and extensible remote procedure calls (RPCs) between the main and browser processes. It also includes a custom webview tag implementation for OOPIFs to enable web browser development.

Electrobun is under active development and the API is subject to change.

"HTML to Markdown" is a tool that converts content written in HyperText Markup Language (HTML) into Markdown, a lightweight markup language. This conversion process can be applied to small code snippets or entire websites.

Here are some potential uses for this type of conversion:

• Website Migrations: Converting HTML webpages to Markdown can simplify the process of moving websites, blogs, or wikis to new platforms because Markdown is widely compatible with content management systems.

• Offline Documentation: Converting web-based documentation to Markdown allows users to download and read the content offline.

• Comfortable Reading: By converting HTML to Markdown, you can remove the visual clutter of a webpage, similar to a browser's "Reader Mode."

This process can provide a cleaner, more focused reading experience.

• Experts.js is a JavaScript framework that simplifies using OpenAI's Assistants API to build multi-agent AI systems. It removes the complexity of managing Run objects and enables linking assistants as tools.
  

• Assistants are AI agents with instructions and tools.

  They can use normal OpenAI tools, function calling, and other assistants as tools.
  

• Tools are subclasses of assistants, acting as reusable components in the system.

  They can be LLM-backed, performing actions based on their parent assistant's requests, or non-LLM tools, implementing custom logic.
  

• Threads are managed context windows for agents, essentially acting as their memory.
  Experts.js handles thread creation and management, ensuring each tool has its own thread to avoid locking issues.
  

• Experts.js provides an easy-to-use "ask" interface to interact with assistants.

  You don't need to manage Run objects directly. It also offers streaming capabilities, allowing applications to receive real-time outputs from the assistants.
  

• The framework includes advanced features like lifecycle hooks and token usage metrics.

  You can customize assistant initialization and track token consumption.

Experts.js enables the creation of multi-tier agent systems where different assistants specialize in specific domains and collaborate to solve complex problems.

For example, a company assistant can have a merchandising expert tool, which, in turn, uses an OpenSearch tool for searching a product catalog.
