Debug artifacts and source maps
We check for debug flags, verbose errors, and source maps that still ship to production.
Debug leftovers hand attackers a map of your code. They also make your app look unfinished to careful users and reviewers.

Replit · Security scan
Is your Replit app secure enough to launch?
Replit's Agent scaffolds a working app inside a full cloud IDE and can deploy it straight from the same workspace, often to a live .replit.app URL.
8 security checks run automatically: secrets, CORS, headers, dependencies, config exposure, auth flaws, debug artifacts, and deployment readiness.
What we look at for Replit
The checks that matter most for Replit apps.
Wardloom always runs the full catalogue — these are the ones Replit projects most often get wrong, based on how the tool tends to generate and deploy code.
Hardcoded secrets and API keys
We look for live API keys, tokens, and credentials sitting in client bundles or source where a stranger can copy them.
One leaked Stripe or OpenAI key can empty a wallet overnight. Catching secrets before launch is the cheapest security win for vibe-coded apps.
Deployment readiness
We look for hardcoded ports and URLs, missing health checks, and environment assumptions that break outside localhost.
A deploy that only works on your laptop is not launched. Readiness checks catch the last-mile mistakes AI tools skip.
Env and config exposure
We look for server-only secrets used in the client, exposed dotfiles, and keys that belong behind the server wall.
AI scaffolds often put REACT_APP_ or NEXT_PUBLIC_ in front of secrets by habit. Config exposure is how private settings become public pages.
Common Replit mistakes
What builders miss with Replit.
- Replit's built-in Secrets manager is safe, but copy-pasted starter code sometimes hardcodes a key anyway.
- A workspace left in debug mode can expose verbose stack traces on the public deployment.
- Ports and internal URLs tuned for the Replit dev environment don't always match the deployed one.
What a scan like this can't see
Wardloom is honest about its limits. Server-side authorization & auth logic is not something a read-only scan can verify from the outside — it requires a connected repo scan or a manual review. A clean result means nothing visible was wrong, not that everything was checked.
