Can PSN and Xbox Live Players Play Together? No—Separate Ecosystems

No. PlayStation Network and Xbox Live are separate, incompatible ecosystems:

• Different servers, protocols, account systems
• Games built for one console don't run on the other
• No cross-platform friends lists or matchmaking

While cross-play exists for some specific games (Fortnite, CoD, etc.), it's not universal and doesn't allow adding friends across platforms.

PSN and Xbox users cannot interact via their native online services.
