Access control is the first thing to verify
Generated full-stack apps share one dominant weakness: data access that confirms a user is logged in but not that they own the specific record. That single gap is the most exploited bug class in real apps, and it is invisible in a demo where you are the only user.
- Per-record ownership checks
Confirm every read and write proves the row belongs to the requester, not just that someone is authenticated.
- Server-side validation
Inputs must be validated where the user cannot bypass it. Client-side checks are UX, not security.
- Secrets stay server-side
Any key reachable from the browser is public. Keep credentials off the client and rotate anything exposed.
Make it survive real data and real traffic
Apps feel instant with a handful of rows. The patterns that fall over under load are deterministic and findable before launch: queries inside loops, reads with no limit, and filters on unindexed columns.
- No N+1 queries
Lists and feeds should not fire one query per row.
- Bounded result sets
Pagination or limits on anything returning a collection.
- Indexed filters and sorts
So common queries do not degrade into full scans.
Price the busiest path before launch
Generated apps lean on managed services with default settings, which is convenient until a hot path bills per operation. Trace your most-used action to the services behind it and model it at real volume - an un-cached AI call or per-request third-party API is where margin usually disappears.
The pre-launch checklist
- Enforce per-record ownership on all data access
Authentication is not authorization.
- Validate and authorize on the server
Re-check inputs and permissions where users cannot bypass them.
- Keep secrets server-side and rotate leaks
Assume anything in the client is public.
- Remove N+1 queries and bound result sets
Make list views scale with data.
- Index hot columns
Avoid full-table scans on common queries.
- Model the cost of your busiest action
Cache or rate-limit per-operation costs.
- Verify dependencies are real and pinned
Guard against hallucinated-package supply-chain risk.

Can I launch a Base44 app to real users as-is?
It will run, but treat the first build as a starting point. Before launch, verify access control, server-side validation, secret handling, scalable queries, and a cost model - the same review any generated code needs.
What is the biggest risk in a Base44 app?
Broken access control: data rules or endpoints that check whether you are logged in but not whether you own the specific record. It is the most exploited class of bug and the highest priority to verify.
How do I keep a Base44 app safe as I add features?
PeakStack connects to your repo and scores security, scalability, and cost on every commit, so regressions surface the moment they land instead of at launch.
