  3. Code-Server

    VS Code in the browser

    Project mention: Self-hosted dev sandboxes with preview URLs (Docker, Go, no K8s) | news.ycombinator.com | 2026-06-03

    I'm using https://coder.com for all my development containers. I've got mine hooked up to a k8s cluster, but anything that you can provision with Terraform can be used (e.g. docker containers).

  4. Docusaurus

    Easy to maintain open source documentation websites.

    Project mention: I built a GUI-powered Userscript manager for faster userscript creation! | dev.to | 2026-04-03

    I used Docusaurus to host my documentation website. Although it used mdx (based on React) while the rest of my website was using Svelte, there just wasn't a solution that worked nearly as well out of the box. There I made some basic tutorials and wrote documentation for the API.

  5. reactotron

    A desktop app for inspecting your React JS and React Native projects. macOS, Linux, and Windows.

  6. redux-devtools

    DevTools for Redux with hot reloading, action replay, and customizable UI

    Project mention: Zustand: React State Management Without Providers or Reducers | dev.to | 2026-04-21

    Redux DevTools browser extension

  7. react-styleguidist

    Isolated React component development environment with a living style guide

  8. cosmos-js

    Sandbox for developing and testing UI components in isolation

  9. pattern-craft

    Professional-grade background patterns and gradients for your websites and apps. Easily copy and paste into your next project. Crafted with modern CSS and Tailwind for seamless integration.

    Project mention: You Might Not Need Next.js | dev.to | 2025-08-05

    They've reached the free plan limits for server function calls, but, why are function calls needed for a website of this kind? Looking through it, all of the content is static, there's no auth, and in fact, the entire list of patterns is stored in a single typescript file. Seems like there isn't a valid reason to use a server, using Next.js was the default way and they just went with it. Had they used Vite or Next.js's static export, they could've hosted their website for free in a static hosting site like Github Pages or Cloudflare Pages.

  10. Reactime 6.0: State Debugger for React

    Developer tool for time travel debugging and performance monitoring in React applications.

    A free open-source tool that helps you to monitor your bundle size on every commit and alerts you on changes.

  15. envilder

    One secret mapping for local dev, CI/CD, and runtime. Envilder resolves cloud secrets from your own vaults without SaaS middlemen, duplicated config, or .env drift.
