Hey HN,

I'm Sindre, CTO of Scrimba (YC S20). We originally launched Scrimba to make video learning more interactive for aspiring frontend developers. So instead of passively watching videos, you can jump in an experiment with the code directly inside the video player. Since launch, almost two million people have used Scrimba to grow their skills.

However, one limitation is that we've only supported frontend code, as our interactive videos run in the browser, whereas most of our learners want to go fullstack—building APIs, handling auth, working with databases, and so forth.

To fix this, we spent the last 6 months integrating StackBlitz WebContainers into Scrimba. This enables a full Node.js environment—including a terminal, shell, npm access, and a virtual file system—directly inside our video player. Everything runs in the browser.

Here is a 2-minute recorded demo: https://scrimba.com/s08dpq3nom

If you want to see more, feel free to enroll into any of the seven fullstack courses we've launched so far, on subject like Node, Next, Express, SQL, Vite, and more. We've opened them up for Hacker News today so that you don't even need to create an account to watch the content:

*Other notable highlights about our "IDE videos":*

- Based on events (code edits, cursor moves, etc) instead of pixels - Roughly 100x smaller than traditional videos - Recording is simple: just talk while you code - Can be embedded in blogs, docs, or courses, like MDN does here: https://developer.mozilla.org/en-US/curriculum/core/css-fund... - Entirely built in Imba, a language I created myself: https://news.ycombinator.com/item?id=28207662

We think this format could be useful for open-source maintainers and API-focused teams looking to create interactive docs or walkthroughs. Our videos are already embedded by MDN, LangChain, and Coursera.

If you maintain a library or SDK and want an interactive video about it, let us know—happy to record one for free that you can use however you like.

Would love to answer any questions or hear people's feedback!

Legal red tape, overpriced attorneys, or not knowing where to start when life hits you with a legal problem?

We’re building ProSe — an AI-native legal platform designed to help you research, strategize, and act in your own legal matters with confidence. It’s like having a law firm in your pocket (minus the billing clock).

Every year in the U.S., over 70 million people face legal problems — from unfair medical bills and debt collection to landlord disputes, family issues, and civil claims. Most of them never get the help they need. Lawyers are expensive, courts are confusing, and legal aid is stretched thin.

Think:

Personalized legal guidance, explained clearly

Smart form-filling with AI reviewing every detail

Case-specific playbooks, automatically generated

Legal research agents trained on real court data

Document analysis, flagging risk and opportunity

AI chat for objections, filings, and strategy on the fly

All in plain English. All in one place. No jargon. No paywalls. No intimidation.

We’re not replacing lawyers. We’re filling the massive access-to-justice gap for the 70M+ Americans who face legal problems every year and can’t get help.

Coming soon. Would love your feedback.
