Vite .env Example and Validator
Vite only exposes variables prefixed with VITE_ to client-side code. Use this page to review that boundary and then validate the file.
Use Cases
- Audit VITE_ variables before release
- Find duplicate development and production keys
- Build a reusable .env.example for a Vite app
Workflow
- 1Paste your .env, .env.local, or .env.production content.
- 2Scan for insecure URLs, duplicate keys, and empty values.
- 3Download an example file after replacing private values.
Practical Tips
- Do not put API secrets behind VITE_ prefixes.
- Use mode-specific files for development and production differences.
- Keep public analytics IDs separate from backend credentials.
Common Questions
Are VITE_ variables public?
Yes. Vite exposes VITE_ variables to browser code, so they should not contain private tokens.
Can this help with .env.production files?
Yes. You can paste any Vite environment file and validate formatting and common security issues.
