PWA → APP STORES
The PWA builder that ships to every store
From PWA to packaged app
A PWA is the perfect source: a manifest, icons and an app shell. SaaSToStore wraps it into the formats each store needs — a signed .aab via TWA or Capacitor for Android, and an MSIX via the PWABuilder engine for the Microsoft Store — without you touching a CLI.
Build your PWA app in 3 steps
1. Paste your PWA URL
We read your manifest, icons and theme color automatically.
2. Pick your targets
Android, Desktop, or both — across up to 7 stores.
3. Build and publish
Get signed artifacts and publish, or download and submit yourself.
Every store from one PWA
- Signed Android App Bundle (.aab) and APK
- Microsoft Store MSIX via the PWABuilder engine
- Desktop installers: Windows .msi, macOS .dmg, Linux .AppImage
- Amazon, Samsung, Snap Store and Flathub
- Offline support carried over from your service worker
Frequently asked questions
How is this different from Microsoft's PWABuilder?+
SaaSToStore uses the PWABuilder engine to generate the Microsoft Store MSIX, but goes further: it also produces a signed Android .aab, desktop installers, and publishes to 7 stores — all in one hosted flow, no CLI.
Does my PWA need a service worker?+
For Android via TWA, yes; without one we use a Capacitor build, so any installable PWA works. For desktop, a service worker is optional.
Can I publish my PWA to Google Play?+
Yes. SaaSToStore wraps your PWA in a Trusted Web Activity and produces a signed .aab accepted by Google Play.
Which stores can a PWA reach?+
Google Play, Microsoft Store, Amazon Appstore, Samsung Galaxy Store, GitHub Releases, the Snap Store and Flathub — seven in total.
Do I keep offline functionality?+
Yes. If your PWA ships a service worker with caching, that offline behavior carries into the packaged app.
