Production Hardening Kit cover

Tutorials stop at “it works.”

This is the part that stops abuse: a tampered client cannot spam your tables, exceed a free-tier cap, read another user's files, or rewrite its own audit trail.

What you get

⏱️
Rate limiting, no Redis

Per-user, per-action limits in pure Postgres, atomic and race-safe via INSERT on conflict.

🔞
DB-enforced caps

A trigger caps rows-per-user, so a patched client or direct API call cannot exceed a limit.

🔒
Private storage, signed URLs

An owner-scoped private bucket, the fix for the most common Supabase data leak.

📜
Immutable audit log

Append-only, cannot be updated or deleted, blocked even for the service role.

🧩
Four independent migrations

Apply only the ones you want, each is self-contained.

📝
Client helpers

checkRateLimit and signed-URL upload/fetch, ready to import.
