Deployment problems it can diagnose

It recognizes the errors that most often stop a website or web app from building, starting or working after deployment.

Build errors — TypeScript errors, failed installs and build scripts that don't exist.
Missing packages or modules — Imports that work on your computer but can't be found on the server.
Node.js version problems — A host running an older Node.js than your project needs.
Wrong build output folder — Hosting settings that look for your built site in the wrong folder.
Missing environment variables — Keys and settings your production host doesn't have yet.
Blank page after deployment — Scripts and styles that load from the wrong path.
404 after refreshing a page — Single-page apps that need every route sent to index.html.
Production still calling localhost — API requests that still point to your own computer.
Login redirect problems — Sign-in redirects that point to localhost or the wrong domain.
Secrets exposed to the browser — Private keys shipped in the frontend, where anyone can read them.

Paste the error — Copy the red lines from your build log, hosting dashboard or browser console.
See the likely cause — Profit Studio checks it against known deployment errors, right in your browser.
Fix it and verify — Follow the steps, confirm it worked, then continue with the right guide.
