## What it is
Bubblewrap is a Node.js CLI and library from GoogleChromeLabs that generates, builds, and updates Android application projects that launch existing Progressive Web Apps via Trusted Web Activity. It also includes a validator library for checking TWA projects against quality criteria.

## Use cases
- wrap a pwa into an android app
- generate an apk from my progressive web app
- publish my website to the google play store
- create a trusted web activity project
- update an existing twa android app
- validate a trusted web activity project

## When to choose
- you have an existing PWA and want a Play Store-ready Android app without writing native code
- you want CLI automation or programmatic generation of TWA projects
- you need to keep an Android wrapper app in sync with your web app

## When to avoid
- you need a fully native Android app with custom native features beyond a TWA wrapper
- you prefer a GUI workflow, in which case PWABuilder may be simpler
- you are targeting iOS or desktop rather than Android
