SSR with React is simple using Nextjs. Additionally, SSR has advantages like performance and SEO. Better performance and SEO must be advantageous to everyone, right? This got me to thinking: Given the advantages I just listed, why not make every program SSR? When is SSR not a good idea?

1-Slower page transitions:
browsing from page to page is often much slower with SSR than on CSR — at least if your pages contain heavy/complex data. With SSR you’re basically rendering your app twice, once on the server, and once on the client.
2-Vulnerability:
SSR sites are harder to keep secure because they have a bigger surface to attack than CSR sites. This is however not an issue if you or your developers know what they’re doing.
3-Complex caching:
configuring your cache is usually more complex on SSR sites than CSR sites.
4-Server cost:
SSR often needs a bigger and more powerful server to provide high-performance than CSR.
5-Higher latency:
SSR sites tend to get a high latency if you get lots of traffic at the same time, which delays/slows down the browsing experience for everyone. CSR doesn’t suffer from this nearly as much. Latency is also known as ping rate which is usually measured in ms (milliseconds).
