A self-hosted app factory for solo founders
One idea in. A store-ready iPhone and Android app out.
Starwisp runs in your GitHub and your vendor accounts, on your own Anthropic API key. It builds a secured Expo app with a backend and automates your own uploads to TestFlight and Google Play internal testing. No human approvals until the stores' own review.
Runs on Claude. You bring the API key and pay Anthropic directly. Not affiliated with or endorsed by Anthropic.

Console shown with demo data. Screens may change before release.
You own it
Your code, your data, your bill.
- The app lives in your GitHub, deployed to your Cloudflare, with data in your Supabase.
- Your keys stay in your GitHub secrets. We never see, store or proxy them.
- No credits to burn and no revenue share. If you stop paying for updates, the software keeps running.
- No daily license check. The only calls to this site are the optional release-feed read and your own update downloads.
What you still do yourself
- Open about eight vendor accounts (GitHub, Cloudflare, Expo, Supabase, Anthropic, Resend, Apple, Google).
- Pay Apple ($99/yr) and Google ($25 once). Those fees are third-party figures and may change.
- Pass store review. A new personal Google Play account also needs 12 testers for 14 days before production access.
- Check the output. AI-written apps still need a human look before real users.

$100–200 typical Anthropic spend per app (estimate)
The plausible band is $45–$400. We have not yet measured this in dollars on a real API-key run, so it is labelled an estimate until we have. See the full table.
14-day refund until your first factory run completes. Refund policy.
Proof
Real runs, including the ones that fail.
No public runs yet.
We would rather show nothing than invent something. Each real run will be logged here with its idea, hours, measured API cost and outcome, failures included.
Straight answers
Before you ask.
Do I need my own Claude account?
Yes. You bring your own Anthropic API key. Usage is billed to you by Anthropic, at Anthropic's prices. We never see, store or resell your key, and we don't sell Claude access.
Can I use my Claude Pro or Max subscription?
No. Claude Pro/Max subscriptions can't be used. Anthropic directs products and automation to API keys.
Is this made or endorsed by Anthropic?
No. It runs on Claude. We are not affiliated with Anthropic.
Does it publish my app for me?
No. It automates your own uploads, from your own Apple and Google accounts, to testing tracks. You decide when to submit for review, and the stores decide whether to approve. Rejections, suspensions and approvals are between you and them.
What if I stop paying for updates?
Nothing stops. You keep running the last version you were entitled to. You just don't receive releases published after your update window ends. Pricing and renewals.
What does the license check?
Your key is verified offline. There is no daily phone-home. See Security for the complete list of calls to this site.
