Free App Builder — Build and Publish a Real App at No Cost
Mis à jour le 23 juillet 2026
What "free" actually means here
Your free build is a real signed app, not a preview locked inside another app. It carries a small SaasToStore badge and targets Google Play. When you're ready to remove the badge and add your own logo, a one-time upgrade does it — no subscription required.
Build your free app in 3 steps
1. Paste your website or PWA URL
Any HTTPS URL works — built with a no-code tool or hand-coded.
2. Run the free build
We generate a signed .aab and APK with your icon, no credit card needed.
3. Install or publish
Download and test on any device, or upload to Google Play.
Free vs paid — what changes
- Free: 1 signed build, Google Play, SaasToStore badge
- Solo (9€ one-time): your own logo, no badge, 1 store
- Launch (from 21€): Android + Desktop, 7 stores, push notifications
- No subscription required — pay once, keep your artifacts
- Your keystore is encrypted and yours forever
Why most free app builders aren't really free
Most platforms advertising "free app builder" give you a preview that only runs inside their own app or a simulator. You can't download an installable file, you can't submit to a store, and the moment you want to do anything real, you hit a paywall. Some require a monthly subscription just to export. SaasToStore takes the opposite approach: your free build is a real, signed .aab and APK that you download and own. Install it on any Android device, send it to a friend, or submit it to Google Play. The only catch: a small SaasToStore badge appears in the splash screen.
What your free build includes
- A signed Android App Bundle (.aab) accepted by Google Play
- An APK for direct installation on any Android device
- Your app icon, automatically resized from 48px to 512px
- Your app name and a valid package name (com.saastostore.yourapp)
- A secure, encrypted keystore stored for future updates
- AI-generated store description and screenshots
- 30-day download window for your build artifacts
When to upgrade — and when not to
If you're testing an idea, showing a prototype to a client, or building an internal tool for a small team, the free build may be all you need. Upgrade to Solo (9€) when you want your own logo and branding — it's a one-time payment, not a subscription. Upgrade to Launch (from 21€) when you want desktop builds for Windows, macOS and Linux, publishing across 7 stores, or push notifications to engage your users. The Pro plan (79€/month) is for teams shipping frequent updates across all platforms.
Your keystore is yours — forever
When your app is built, we generate a unique cryptographic keystore and encrypt it with AES-256. This keystore is what Google Play uses to verify that updates come from the same publisher. It belongs to you — not to us. If you build an update later (free or paid), we reuse the same keystore automatically. This means your users get seamless updates and you never lose publishing rights to your own app.
