Scanning your v0-generated app
v0 is strong at generating polished UI and wiring it into a modern web project. One security detail is easy to miss there: environment variables prefixed to be public are shipped to the browser on purpose. That is correct for a public site URL or an analytics ID, but wrong for a database URL or an API secret. When a real secret is given a public prefix, it goes out with every page load, and once it is bundled it looks like ordinary app data, so a check of the deployed site alone will not reliably tell it apart.
This guide uses a source scan. ShipSafeScan reads the repository itself and runs 50 checks in four groups: hardcoded secrets, code security anti-patterns, code quality, and repo health. Its 11 secret checks detect hardcoded credentials for more than 10 providers, including AWS, GitHub, Google, Stripe, OpenAI, Anthropic, and Slack, so a secret that carries a public prefix or was pasted into a config file is flagged with the file and line where it lives. The 21 code anti-pattern checks, split into 14 security and 7 quality, also catch injection and cross-site scripting patterns that generated components can introduce.
Reading the repo is what makes the difference. A value marked public in the source is invisible as a mistake on the running site, yet it is plainly there in the repository. The scan can point at the exact line, and because the rules are deterministic, the same commit always yields the same score. You can confirm that only non-sensitive values carry a public prefix, that real secrets are called from a server route instead of a client component, and that nothing sensitive was committed to a config file.
The output is a single score and a short issue list, so you can fix things before you ship. It is free, with no install and no sign-up. If a real secret is flagged behind a public prefix, move it to a server-only variable, call the external service from a server route rather than a client component, and rotate anything that was already public. Then run the scan again on the new commit to confirm the finding is cleared.
How to scan a v0-generated app for secrets and security issues
- Step 1
Copy your public GitHub repo URL
Open the public GitHub repository for your v0-generated app and copy its URL. ShipSafeScan reads public repos, no install and no sign-up.
- Step 2
Paste it into ShipSafeScan and start the scan
Paste the repository URL into the scan box and start it. The scan reads the repo source, not just the live site, and runs 50 checks across secrets, code security anti-patterns, code quality, and repo health.
- Step 3
Review the score and flagged issues
Read the score and the issue list. It flags hardcoded credentials for 10+ providers such as AWS, GitHub, Google, Stripe, OpenAI, Anthropic, and Slack, plus injection and XSS anti-patterns, with the file and line for each finding.
- Step 4
Fix, then rescan to confirm
Move any real secret out from behind a public prefix to a server-only variable, call external services from a server route, and rotate what was public. Run the scan again on the new commit to confirm the issue is gone, since the same commit always yields the same score.
What the scan checks
- It scans your public GitHub repo source for 50 checks across secrets, code security anti-patterns, code quality, and repo health.
- It detects hardcoded credentials for 10+ providers (AWS, GitHub, Google, Stripe, OpenAI, Anthropic, Slack) plus injection and XSS anti-patterns.
- The rules break down as 11 secret checks, 21 code anti-patterns (14 security and 7 quality), and 18 repo-health checks.
- It is free, with no install and no sign-up. It reads the repo source, not just the live site, and the same commit always yields the same score.

Scanning a v0-generated app: frequently asked questions
How do I scan my v0-generated app for an exposed secret?
Paste your public GitHub repository URL into ShipSafeScan. Its 11 secret checks read the source, including values exposed through public environment prefixes, mask what they find, and report it with a score so you can rotate and relocate them.
What does ShipSafeScan check in a v0 app?
It runs 50 checks on your public repo source: 11 secret checks, 21 code anti-patterns split into 14 security and 7 quality, and 18 repo-health checks. That includes hardcoded credentials plus injection and XSS anti-patterns.
Do I need to install anything or sign up?
No. Scanning a public repository is free, with no install and no sign-up. The scan reads the repo source rather than the live site, and the same commit always yields the same score.
