The verdict
Centrifugo appears in 1 AI-ranked category — best position #2 for realtime websocket platform.
Best self-hosted value: open-source, language-agnostic, fast, and unusually complete, with presence, history, recovery, delta compression, multiple transports, strong SDKs, and Redis-backed scaling. Near-tie with Ably if the team can operate it.
Gemini High-performance Go-based open-source real-time messaging server supporting WebSockets, SockJS, and gRPC; scales horizontally via Redis or NATS and provides language-agnostic APIs without per-message fees; near-tied with Soketi for self-hosting but wins on native feature depth and multi-broker support.
Claude Mature open-source realtime server that scales to millions of connections via a Redis/Nats engine, is language-agnostic (works behind any backend), and supports channels, presence, history, and JWT auth out of the box — the strongest self-hosted platform for teams that want control and no per-message billing.

Where Centrifugo falls short, per the models
- GPT You own global availability, Redis, scaling, upgrades, and monitoring; it is not a zero-operations choice.
- Claude You own the ops — scaling, HA, and monitoring are on you; there's no first-party fully-managed cloud at the maturity of Ably/PubNub.
- Gemini Demands self-managed deployment, scaling, and infrastructure monitoring without an official turnkey global SaaS offering.
