Replit security check
Replit app security scanner
Check a public Replit repository for known dangerous patterns before deployment, with source-level evidence for every finding.
No account required. Public repositories only. Preview links expire after 24 hours.
Source-level evidence
Every match points to a rule, file, line, and concrete remediation. No invented narrative.
Built for AI-app patterns
Checks cover exposed provider keys, missing auth, injection, unsafe LLM flows, web risks, and insecure configuration.
Honest result
A clean result means no applicable known-pattern issues were found. It is not a security certification.
Why add CodeCordon to a Replit workflow?
Replit makes building and hosting accessible. CodeCordon provides a separate source-level check for common security mistakes before release.
CodeCordon currently runs 31 deterministic checks. JavaScript, TypeScript, and Python receive the deepest coverage, while other supported languages receive selected pattern checks.
