The most compelling argument for private servers is archival.
FGO is structured like a visual novel. When the official servers shut down (assuming the game doesn't become an offline app like Mobius Final Fantasy or Animal Crossing: Pocket Camp did), Lostbelt 6: Avalon le Fae—a story praised as one of the best in mobile gaming—becomes inaccessible to new players.
Private servers are the only bulwark against this "digital oblivion."
Most private servers run on outdated versions of the game (e.g., Version 1.x or 2.x). They often lack the most recent Quality of Life features, Servants, and story chapters found in the current global or Japanese versions. Running a server that syncs with the official game is technically difficult and legally risky, so private server admins are often slow to update.

Don't do it.
FGO is a marathon, not a sprint. The pain of the gacha is what makes pulling your waifu actually feel like winning the Holy Grail. A private server kills that emotion instantly. It turns Fate/Grand Order from a journey into a boring sandbox.
If you are really desperate to play with maxed-out servants, just watch a "NP Showcase" on YouTube. It's safer, and the video won't steal your credit card info.
Stay safe in the real Chaldea, Masters. The gacha salt is better than the malware blues. Creating an FGO private server is not a

I notice you're asking about a "feature: fgo private server" — likely referring to Fate/Grand Order.
To be clear upfront: There is no official private server for FGO. The game is server-authoritative, and all critical data (servant inventory, quest progress, Saint Quartz, summoning results) is stored on Aniplex/Delightworks' (now Lasengle's) servers.
However, I can explain what people sometimes refer to or request:
Deployment: Docker + Docker Compose or Kubernetes for scalability; Nginx as reverse proxy & TLS termination.
