Free. Here is how that works.
No plans, no trial, no account. We would rather explain the model than hide it behind a "Pro" button.
What free covers
- The PWA builder: manifest, service worker (all three caching modes), offline page, icon set, setup guide
- The Android app builder: signed APK, custom icon and splash screen, push and AdMob integration fields (the APK and the AAB for Google Play, both free)
- Trusted Web Activity test APK and
assetlinks.jsongeneration - All ten asset tools - icon resizer, screenshot frames, QR codes, palette extraction, listing text, feature graphic, listing preview, social kit, promo video, Play listing checklist
- Unlimited builds. Build a test version, change the colour, build again.
- Every guide on this site
The APK and the AAB are free too
Google Play accepts new apps only as an Android App Bundle. In the Android app builder, the APK and the AAB are both free, with no limit on builds: both files download instantly from the last step, signed with a key that stays the same for the same package name, so later builds update the app. The PWA builder itself, including its Trusted Web Activity test APK and assetlinks.json, stays free; if you go the TWA route, Bubblewrap or PWABuilder produce the AAB from the same manifest at no cost.
How it is paid for
This website shows display advertising. That revenue pays for the domain, the hosting and the time it takes to keep the generated files current with browser and Google Play changes. The trade is transparent: you see ads while you are here, and what you download is clean - no ads, no analytics beacon, no "made with" badge, no call home.
Because the builders run in your browser, our per-user cost is close to zero, which is why there is no need for a usage cap.
Costs you will still meet elsewhere
We are not the only party involved, so a straight answer about the rest:
| Item | Cost | Notes |
|---|---|---|
| HTTPS certificate | Usually free | Included by most hosts and every CDN; required for any installable web app. |
| Google Play developer account | US$25 one-time | Only if you want a Play listing. Personal accounts also need a closed test with 12 testers for 14 days before production. |
| Apple App Store | US$99 per year | Not needed for an installable web app on iPhone - users add it from Safari. Only relevant if you want a store listing, which this site does not produce. |
| OneSignal push | Free tier available | Limits change; check their current plan page before you depend on it. |
| Your own hosting | Whatever you pay now | The generated files add a few hundred kilobytes to your site. |
Will this ever become paid?
The builders and tools that exist today stay free. If we ever add a paid service - hosting, for instance - it will be a separate, clearly labelled thing, and nothing that is free now will move behind it.
