01 / What usually goes wrong on Replit

The defaults that bite.

These are the mistakes we see most on sites built with Replit. Not your fault: they are what the builder does unless you tell it otherwise.

01Projects and databases can default to public or shared.
02The agent has been known to act against production data.
03Secrets and keys can end up in the bundle.

The fix, in short

Separate dev and prod databases, restrict access, keep backups, and never let an agent touch production.

SECURITY
A-01
Anyone can read your database
Your Supabase table answers to anyone who asks, no login needed. That is your users' data, readable by strangers. We ask once, read-only, and report what came back.
CRITICAL
A-04
Your Firebase database is open
Your Firebase data can be read without logging in.
CRITICAL
S-01
Your master key is inside the page
The Supabase service key sits in your site's code. Whoever reads it owns your whole database, every lock ignored.
