Next.js renders server component twice even with ReactStrictMode disabled — still happens in production Help

[theanuragg]

Summary

I'm seeing my page render twice even after turning off ReactStrictMode.

The component uses \useEffect to fetch images from the backend. This still happens in production (Vercel deployed).

Is this normal in RSC/Next 13+? Or am I missing a fix?

So I’m using client components across the board, including in page.tsx. I get that skipping Server Components can cause double API calls because of client-side hydration — that part makes sense.

But hear me out: even components that don’t fetch data (like buttons and inputs) are rendering twice. That’s what made me think this isn’t just about API calls. It seems like React’s hydration behavior and how it handles effects on the initial load is playing a big role here too.

Curious if anyone else has run into this or has thoughts on what’s really going on behind the scenes?

Hi,

You can do:

npx react-scan@latest https://vras-ai-theanurags-projects.vercel.app/

And that'll help you identify the issue. I think, it can be related to ThemeProviders, or Auth Providers in your app.

I can't figure out the problem i think the problem likely has to do with useEffect, should i try shifting to react-query

Mmm can you do a profile run using ReactDevTools? And post back with screenshots and such?

What component has this useEffect? Could you link to it? GitHub search hasn't indexed your repository yet, so I can't search just yet

I tried digging into it, but I couldn't find the exact issue yet. Every component except the landing page is getting rendered twice.
