Build the future of web based coding experiences, from interactive tutorials to instant production-ready dev environments.
From interactive tutorials to full-blown IDEs, build instant, interactive coding experiences backed by WebContainers: the trusted, browser-based runtime from StackBlitz . On the SvelteKit team, we've fantasized for years about being able to build fully interactive learning material for full stack frameworks. With WebContainers it went from 'impossible' to 'easy' almost overnight. As a team working on educational products, StackBlitz WebContainers has been an invaluable tool for us. The ability to embed full-stack applications with customisable, interactive coding environment directly into our products has greatly enhanced the learning experience for our users.

I've been making JavaScript sandbox alone for 6 years2022 · playcode.io · ▲397Hi HN! Thanks for your attention to my post. It was a big challenge to run most of Node.js packages in browser, fast moreover. Virtual File system, resolve import/export. I got cold many times, depressions, burned out, yet still alive and finished it. Many guys helped me with an advice. Many users give a lot of positive feedback. There are 200,000 monthly unique users. I work full time now because of the freemium business model. To be honest - I am happy after many years of hard work.
Node.JS in the Browser – An Open-source Alternative to WebContainersAug 2026 · developer.puter.com · ▲6This is a Node.js compatible runtime in the browser. It supports CLI apps, Vite, and some agents (like Pi Agent) as well. Some notes: - This runs all code in a web worker using the host javascript runtime with rewrites for module loading and AsyncLocalStorage support using Oxc compiled to WASM. - Most of the libraries are bundled straight from Node.js upstream with light overrides where needed, ensuring compatibility. Libraries were only reimplemented where really needed - Despite having great integrations with the Puter desktop and APIs, this can be used completely seperately with OPFS…

I've been frustrated with dependency hell and clutter on my VPS from dev, so I built Devbox: a lightweight, open-source CLI tool that spins up isolated development environments using Docker. Each project runs in its own container, but your code stays in simple flat folders on the host machine—no messing with volumes or sync issues. Environments are disposable, so you can nuke and recreate them without losing your work. Key features: - Instant setup: `devbox init my-project` and you're in a fresh env with `devbox shell`. - Configurable via JSON: Define packages, services, and more in a…

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
