10 Things Every Programmer Must Do Before Launching a Website 🚀

Launching a website isn’t just about design and features.
A few small checks before going live can save you from big problems later ⚠️

Here are 10 essential things every programmer should do 👇
1️⃣ Remove test & debug code 🧹

Delete:
-test routes
-debug logs
-admin test accounts

Anything left for testing can become an entry point later.

2️⃣ Update everything 🔄

Before launch, make sure:
-frameworks are up to date
-plugins and libraries are updated
-dependencies have no known issues
-Outdated code = easy target 🎯

3️⃣ Secure environment variables 🔐

Never hard-code:
-API keys
-database passwords
-secret tokens

Use environment variables and keep them private.

4️⃣ Validate all user input ✍️

Assume all input is untrusted:
-forms
-URLs
-headers
-file uploads

Always validate and sanitize.

5️⃣ Set proper file & folder permissions 📁

Make sure:
-config files aren’t public
-upload folders are restricted
-sensitive files can’t be accessed directly

One wrong permission can expose everything.

6️⃣ Add basic security headers 🧱

Headers like:

• Content-Security-Policy
• X-Frame-Options
• X-Content-Type-Options

They’re simple, but very effective.

7️⃣ Enable HTTPS only 🔒
-Force HTTPS
-Redirect HTTP → HTTPS
-Use a valid SSL certificate

No exceptions. Ever.

8️⃣ Create backups before launch 💾

Always have:
-database backup
-file backup

If something breaks on day one, backups save lives.

9️⃣ Run a security check 🔍

Before publishing:
-scan for common issues
-review configs
-check exposed endpoints

Even a quick automated check can reveal problems you missed.

🔟 Limit admin access 👤
-Strong passwords
-Minimal admin users
-Protect admin panels

If everyone is admin, no one is safe.

💡Security isn’t about perfection.
It’s about reducing obvious risks before real users arrive.
