Nitro / JSI Sockets vs Pure JS WebSockets in 2026
Not financial advice. Verify claims independently.
In 2026, JSI/Nitro-backed socket stacks promise lower overhead into native. Pure JS WebSockets remain easier to reason about, debug, and Expo-manage.
Use native sockets when profiling shows encode/decode or bridge traffic as the cliff. Otherwise ship JS sockets, measure Micron-night replays, then decide. Fashionable native modules are still modules you must maintain through RN upgrades.
