Electron (electron/electron on GitHub) is an open-source, MIT-licensed framework for building cross-platform desktop apps with JavaScript, HTML, and CSS on top of Node.js and Chromium. The README covers installing it as a dev dependency through npm, lists platform support for macOS, Windows, and Linux, and points to a companion tool, Electron Fiddle, for trying the API before starting a full project.

Atom was a cross-platform, hackable text editor built on Electron that shipped with deep customizability baked in — you could swap out themes, install packages from a large ecosystem, and modify the editor's core behavior through JavaScript. Its main appeal was that it married the accessibility of a GUI editor with the extensibility of a code editor: the Flight Manual and API reference were well-maintained, and the package system gave it a second life beyond what GitHub shipped out of the box. The catch, and it's a significant one, is that Atom was officially archived on December 15, 2022 — no new releases, no security patches, no upstream updates, which makes it a poor choice for any new work today. If you're evaluating it for historical reasons or curious about its architecture, the codebase is still worth studying; just don't spin it up for active development.

freeCodeCamp is a free, self-paced curriculum for learning to code, published as open source at freeCodeCamp/freeCodeCamp. It's a 501(c)(3) nonprofit funded by donor support, structured around six certifications in its Full-Stack Developer Curriculum, each gated by required projects instead of open-book quizzes. The repository also carries beta language certifications for developers, interview-prep resources, and the code that runs the live freecodecamp.org platform.

Vue 2, also known as Vue.js 2, is the earlier major version of the Vue JavaScript framework, hosted at vuejs/vue on GitHub under an MIT license. Per the repository's own README, Vue 2 hit End of Life on December 31, 2023, is no longer actively maintained, and the project now directs users toward vuejs/core (Vue 3) and an official migration guide, while leaving Vue 2 itself installable through CDNs, package managers, and GitHub.
