Why we built PortaPack

Ever needed to share a web thing but got tangled in the "how do I send this?" mess? Us too! We wanted something that lets you share interactive prototypes with anyone — no server setup, no "it works on my machine" drama. Just a thing you can drag into Slack, attach to emails, or toss on a USB stick that works perfectly offline.

So we made PortaPack:

A magic little bundler that squishes your entire website into one .html file — super portable and totally bulletproof.

The Problem

Let's be real: modern websites are a jungle of files, dependencies, CDNs, and weird asset pipelines. Great for fancy production sites! Not so great when you need to:

  • Share quick demos with non-techy folks
  • Make self-contained archives that won't break tomorrow
  • Create offline snapshots for testing or presentations
  • Package apps for kiosks or offline devices

And tools like webpack, vite, or parcel? They weren't built with "toss it in an email" portability in mind.

The Solution

PortaPack is a super simple CLI tool (with a Node API too!) that crawls through your site, grabs all the bits and pieces, cleverly tucks them inside, and spits out a single HTML file with everything included — even the fonts!

1npx portapack ./index.html -o bundle.html

You get a magical self-contained webpage with:

✅ All your styles baked in ✅ All your JavaScript tucked inside ✅ Fonts and images embedded ✅ Optional minification if you want it smaller ✅ Works offline and no CORS headaches

Who's It For?

  • Designers showing off interactive mockups
  • Developers sharing prototypes that actually work
  • QA folks needing reliable test environments
  • Kiosk builders making offline experiences
  • Anyone tired of saying "hang on, it should work if you..."
