Holdfast

Rescue audit for AI-built apps

Built with Lovable, Bolt or Cursor? Make sure it holds.

AI tools get an app live in days. They also leave the same handful of gaps, and they're quietly confident they haven't. If real customers or payments now depend on your app, get it checked by a senior engineer, and get the worst of it fixed.

The gaps AI tools tend to leave

Data anyone can read

Database tables with row level security off, or rules so loose that your public key opens them. One customer can see another's records.

Keys in the browser

Secret keys pasted into frontend code or prompts, including the database key that ignores every access rule.

Payments that can be faked

Webhooks that trust whatever they're sent, so a forged "payment succeeded" unlocks paid features for free.

Fixes that undo fixes

Each prompt fixes one screen and can break an earlier fix. Nobody has the whole picture, least of all the tool.

No way back

Backups that were never restored, so nobody knows if they work, and no record of what changed when.

Accounts in the wrong hands

Hosting, domain or payment accounts in a freelancer's or a former co-founder's name.
