Show HN: A fast, minimal and offline-friendly web playground
scriptpad.devI built a web-based HTML/CSS/JS editor focused on speed, simplicity, and offline access. No bloat — just open and start coding.
What makes it different: Live Preview – Edit HTML, CSS, and JS side-by-side with instant feedback.
Offline support – Works without internet. You can even install it as a PWA and use it like a native app.
No Login Required – Just visit, code, and preview. Login only if you want to save/share.
Savable & Shareable Links – Save scripts in the cloud and get shareable links.
Customizable Editor – Themes, fonts, auto-format on save, layout tweaks, line wrapping, etc.
Hotkey Support – Power user shortcuts with tooltips showing keybinds.
Download as ZIP – Export your project with HTML/CSS/JS files separated.
Ideal for tinkering, prototyping, teaching, or even building micro-tools. It’s intentionally simple and fast — more features coming soon.

I would love it if it was open source!
Any things similar to this which are open source?
Same, a tool like this would be invaluable if OSS.
I don't know of any sadly.
Very useful and fast
Very nicely done!
Can I use it as a PWA?
Yes. You should be be to install it as PWA on any device. If it’s a desktop device that you are using, you can install it using the install icon in the far right part of the URL search bar. For mobile, “add to Home Screen“ option should do the same on iOS. Android should have a similar option too.
