Is My App Safe to Share?
Your app is safe to share if you have covered the basics: no hardcoded secrets in your code, HTTPS enabled, database access locked down, and basic input validation in place. You do not need to be a security expert — but you do need to run through a short checklist before giving anyone the link.
Why this matters
Sharing your app is a milestone — but sharing it before basic security is in place can expose user data or your own API keys. Most security incidents with builder-made apps happen because the builder skipped a simple step, not because of a sophisticated attack.
What's at stake
If someone accesses your app and finds exposed data or broken functionality, your reputation takes a hit before you even get real feedback. A 5-minute security check can prevent that.
Your checklist.
No API keys or secrets are hardcoded in your source code
CriticalSearch your codebase for any API keys, database URLs, or passwords written directly in code files. Move them to environment variables or your platform's secrets manager.
Your app uses HTTPS
CriticalMost modern hosting platforms (Vercel, Netlify, Replit) provide HTTPS automatically. If you are self-hosting, set up a free SSL certificate with Let's Encrypt.
Database is not publicly accessible without authentication
CriticalIf you use Supabase, check that Row Level Security (RLS) is enabled on every table with user data. If you use another database, ensure it requires credentials to access.
Basic input validation is in place
ImportantAny form or input field should check that the data is the expected type and length before processing. This prevents injection attacks and data corruption.
Error messages do not expose system details
RecommendedMake sure your app shows friendly error messages to users, not raw database errors or stack traces that reveal your tech stack.

Frequently asked questions.
At minimum: no hardcoded secrets, HTTPS enabled, and database not publicly writable. These three checks take less than 10 minutes and prevent the most common security issues.
Yes — sharing with a small group is a great way to get feedback. But even for friends, make sure your secrets are not exposed and your database is protected. A friend could accidentally share your link publicly.
Not necessarily. If your app is a public tool or landing page with no user data, authentication is not required. But if users can create content, store data, or access anything private, you need authentication before sharing.
Fix it immediately. Rotate any exposed keys, patch the vulnerability, and notify anyone who used the app during the exposure window. The faster you respond, the less damage is done.
