The 7 Most Common Deployment Mistakes Beginners Make (And How to Avoid Them)

Deploying your app for the first time is exciting — until it breaks lol.

After helping beginners deploy their projects, I’ve noticed the same mistakes appear again and again.

Here are the 7 most common deployment mistakes beginners make, and how to avoid them:

1. Missing environment variables
Your app works locally but fails in production.

2. Wrong build commands
Especially with React, Vue, Next.js, Django, and FastAPI.

3. Incorrect file structure
Hosting platforms can’t find your backend.

4. Hardcoded secrets
Never do this.

5. Wrong port configuration

Your app runs but isn’t reachable.

6. Not checking logs
Logs tell you everything.

7. Deploying without testing locally
If it doesn’t run locally, it won’t run live.

I’m 17 and building LaunchAlly to help beginners avoid these mistakes entirely.

Hope this helps you ship faster.
