electron/forge

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.

Storybook is a frontend workshop maintained at storybookjs/storybook. It renders UI components and pages in isolation from your main application. Core renderers include React, Angular, Vue 3, Web Components, HTML, Ember, Svelte, and Preact, plus React Native and community support for Qwik and SolidJS. It's released under the MIT license.

Strapi is a self-hosted headless CMS that auto-generates REST and GraphQL APIs from content model definitions you build visually with the Content-Type Builder — no code required on the API side. It ships with authentication, granular roles and permissions, a media library, i18n, and draft/publish workflows out of the box, and the request pipeline (Routes → Middlewares → Controllers → Services) is fully overridable at each layer. TypeScript is first-class and you can pair it with SQLite for local dev or PostgreSQL/MySQL/MariaDB in production. The plugin system and customizable admin panel are real extensibility points, not marketing. The tradeoff: there's no official Docker image (you roll your own from your project), and major version upgrades have been historically painful — the migration docs are thorough but the process still demands attention. Worth it if you need full control over your content infrastructure and don't mind owning the deployment; less ideal if you want something you can set and forget.

microsoft/vscode is the GitHub repository where Microsoft develops the Visual Studio Code editor together with the community, published under the MIT license. The README draws a clear line between this open Code - OSS source and the Microsoft-branded Visual Studio Code product, a separate distribution built from this code plus Microsoft-specific customizations.
