Getting this error in Next.js? You’re not alone.

Hydration failed because the initial UI does not match what was rendered on the server.
This usually happens when your server-rendered HTML doesn’t match what React renders in the browser.
Common causes:

• Using window or localStorage during server rendering
• Rendering different content based on browser-only values
• Incorrect date/time rendering
• Invalid HTML nesting
My first fix:
Move browser-only logic into useEffect, or make the component client-side when necessary.
💡 Tip: Don’t just hide the error. Find out why the server and client are rendering different UI.
