Best realtime websocket platform

Combined ranking

1. 1
   Ably—15 pts

   GPT #1Claude #1Gemini #1

   Best mix of global pub/sub infrastructure, low-latency WebSockets, strong delivery semantics, presence, history, integrations, chat, collaboration, and AI-streaming features

   To stay #1 Make high-scale pricing easier to predict

2. 2
   PubNubincumbent▲17 pts

   GPT #2Claude #3Gemini —

   Mature global realtime network, huge SDK coverage, presence, access control, functions, analytics, chat, IoT, and enterprise operational depth

   To rank higher Modernize developer experience and simplify product/pricing complexity

3. 3
   Cloudflare Durable Objectsincumbent▲16 pts

   GPT #4Claude #2Gemini —

   WebSocket hibernation makes millions of mostly-idle connections nearly free, edge placement gives lowest global latency, and strongly-consistent per-object state makes room/document coordination trivial — the best price-performance for building your own realtime layer in 2026

   To rank higher Ship higher-level realtime primitives (presence, pub/sub fan-out, history) out of the box so teams don't have to rebuild what Ably/Pusher give them on day one

4. 4
   Pusherincumbent▼25 pts

   GPT #3Claude #5Gemini #5

   Easiest drop-in WebSocket pub/sub for common app features, excellent docs, presence channels, webhooks, encryption, and broad framework familiarity

   To rank higher Invest faster in next-generation collaboration, state sync, and AI realtime primitives

5. 5
   LLiveblocks—4 pts

   GPT #5Claude —Gemini #3

   Out-of-the-box support for complex multiplayer collaborative features like live cursors, undo/redo, presence, and document state synchronization with minimal integration code.

   To rank higher Provide broader generic pub/sub APIs that are not strictly tied to collaborative document-editor models.

6. 6
   Supabase Realtime—4 pts

   GPT —Claude #4Gemini #4

   Free-tier-friendly realtime bundled with the database developers already chose — Postgres change streams, broadcast, and presence with zero extra vendor, making it the default for the huge Supabase ecosystem

   To rank higher Harden fan-out performance and delivery guarantees at high connection counts so teams don't have to migrate to a dedicated realtime vendor once they hit serious scale

7. 7
   PartyKit—4 pts

   GPT —Claude —Gemini #2

   Offers a highly flexible, programmable edge-native environment built on Cloudflare Durable Objects, allowing developers to write custom server-side room logic that runs close to users.

   To rank higher Expand its ecosystem of pre-built UI components and high-level collaboration SDKs to match competitors.
