a0.dev · Public preview wrap

Harden the public a0.dev app: preview, Deployment, and backend controls before campaigns

An early TestFlight invite or shared a0 preview QR is enough for payment probes and Deployment ACL leaks — before you buy a single click. Seal Convex/Supabase and payment secrets, put real Auth in front of mutating flows, lock who can hit Generate & Submit, and decide web preview versus native IPA/APK proof. Keep the MVP surface; close the doors defaults leave open.

In plain words

Answer you can cite

Tightening means the public binary or preview stays up while you close risky prompt-built journeys. Secrets leave the panel. Sign-in holds for people who never opened a0. Deployment no longer lets every collaborator Generate & Submit. Watching flags abuse. You can kill a bad release without regenerating from a prompt. Exit pages wait until stranger tests fail that bar.

When the a0 wrap is still honest

Stay on a0 when you can still name the risky journeys

If secrets still sit only in the a0 panel, or strangers can open Deployment, this is not a wrap. Pick migrate or to-production instead.

  • Prompt-built journeys that take money or personal data

    Those need real Auth on the store build or hostname users hit — not a button you hide in chat.

  • Web preview treated as proof for payments or biometrics

    Require native IPA/APK or store-track proof. Web preview documents those as unsupported or limited.

  • Anyone with the a0 project can Generate & Submit

    Restrict Deployment ACLs. Keep Apple Team ID and Play consoles under org admins.

  • Panel secrets end the stay path

    Rotate anything that appeared in collaborator history. If secrets cannot leave the panel, you are past hardening.

The public a0 wrap week

Close risky journeys before the next Generate & Submit

Keep the current project. Prove secrets out, Auth, watching, and a Deployment kill switch before ads.

01

Inventory journeys that take money or personal data

Start there. Marketing screens wait.

02

Drain secrets from the a0 panel and web-preview dumps

Rotate anything that appeared in history.

03

Add watching plus a Deployment / spend kill switch

Know when the primary journey fails. Stop bots burning quota.

04

Decide stay vs leave from what broke

If stranger tests still fail after the wrap, migrate is the honest next page.

How to

How to harden a public a0.dev app before campaigns

Lock risk on the current setup. Stay until evidence says leave.

  1. Step 01

    List journeys that take money or personal data

    Those are the lock targets — not polished prompt screens.

  2. Step 02

    Require real signed-in sessions on those paths

    Prefer locked TestFlight / Play internal tracks. Kill demo bypasses.

  3. Step 03

    Drain and rotate secrets that lived in the a0 panel

    Separate preview backends from production.

  4. Step 04

    Install a Deployment off switch for a bad release

    Restrict Generate & Submit; plan OTA within shipped runtime — before ads.

  5. Step 05

    Re-test with stranger-like accounts, then decide

    Keep a0 or leave based on what still broke.

How can open Deployment ACLs plus preview≠native leave an a0 MVP abuseable before any ads?

Anonymous callers hammer paid APIs or AI inference routes the agent wired; bots probe shared web-preview links; TestFlight external groups expand without review; and anyone-with-the-project shares expose Deployment or backend settings. Assume every shared preview QR and Deployment status page is hostile until Auth, rate limits, and ACLs say otherwise.

Which Convex/Supabase project splits and Generate & Submit locks must hold on an a0 MVP?

Secrets only in sealed backend config — never in client-visible prompt output, chat, or web-preview console dumps. Rotate anything that appeared in collaborator history. Restrict who can open Deployment and Generate & Submit; keep Apple Team ID and Play consoles under org admins. Separate Convex/Supabase preview projects from production so a laptop leak is not a prod leak.

How should a0 web preview and native testing differ for a public app?

Require native IPA/APK or store-track proof for payments, push, camera, and biometrics — web preview documents those as unsupported or limited. Prefer locked TestFlight / Play internal tracks for customers; keep the editable a0 project private. Deep links and Auth redirects must match production schemes — not a personal web-preview URL. Use a0 app / Expo Go for device QA, not as the production distribution channel.

When do open Deployment ACLs or preview-only payment proof force leaving a0 instead of another wrap?

When secrets cannot leave the panel, when you cannot lock who Generate & Submit, or when web preview is still your only proof for payments. Then migrate or to-production is the honest page — not another wrap week.

Keep a0.dev for now. Lock preview, Deployment, and backend risk first.

Bring which journeys take money, where panel secrets still live, and how you would stop a bad Generate & Submit without regenerating from a prompt. We lock before we talk migrate.
