A progressive web app to help you design eBooks



If you’re using a mouse/touch:

  • click the checkbox to check
  • click the label to display details
  • click reset to… reset the checklist

If you’re using a keyboard:

  • press “tab” to navigate items
  • press “enter” to check
  • press “space” to display details
  • press “backspace” to reset the checklist

Don’t worry, your checklist is autosaved: you can close this website, your current checklist will be retrieved when reopened.


If you’re on iOS/Android/Windows 8–10, you can actually install this web app. Just visit the page and “Add to homescreen”.

Thanks to service workers, it will even work offline on Android, Chrome, Opera or Firefox (appcache fallback for iOS).


The eBook Design Checklist is part of the Blitz Project. It’s a progressive web app which aim is to help you design your eBooks.

It is currently in v.1.0.2 and available on this page.


This web app is just a glorified form with checkboxes.

  • We’re using JS to toggle details.
  • We’re using localStorage (with cookie fallback) to store checked checkboxes + progress (bar’s width).
  • We’re using Service Workers and appcache (fallback) to make it work offline.
  • Keyboard features are implemented via JS when needed.

And that’s it.

What LGPL3 actually implies

You can fork this repo and make your own checklist/web app, say for Quality Assurance, InDesign’s export cleaning, metadata, etc. You can use it in commercial projets but your modifications to this specific part (consider this a library) should then be released with a LGPL3 license. Attribution is needed in any case.

Why LGPL3 OMG it’s not MIT like the Blitz Framework!

The eBook dev ecosystem is a nightmare, we need eBook tools. And fast!

Very few people actually release those tools. Now it’s just a checklist so why would you want to keep this closed source, huh?

You can’t perform that action at this time.
