AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

A Python client for Supabase Realtime that enables real-time communication via Broadcast (ephemeral messages), Presence (state synchronization), and Postgres Change Data Capture (CDC) for listening to database changes.

Low friction installation with only three runtime dependencies (pydantic, typing-extensions, websockets). Actively maintained with recent releases.

MIT license permits unrestricted use, modification, and distribution with minimal legal friction.

Usage

pip install realtime

from realtime import AsyncRealtimeClient

client = AsyncRealtimeClient("ws://localhost:4000/websocket", "api-key")
channel = client.channel("test-channel")
await channel.subscribe(lambda status, err: print(status))

Requires Python 3.9 or later; a running Supabase Realtime server or Supabase project endpoint; and a valid JWT API key with exp and role claims.

Verdict: A well-maintained, actively developed client for Supabase's real-time features with minimal dependencies and permissive MIT licensing. No known vulnerabilities and broad Python version support (3.9–3.14) make it a solid choice for applications needing real-time database sync, presence tracking, or low-latency message broadcasting.

Needs verification

Whether the package's async-only API design (AsyncRealtimeClient) is suitable for synchronous-only applications or if blocking wrappers are available.
Performance characteristics and latency guarantees under high message volume or many concurrent channels.
Whether Row-Level Security (RLS) integration is fully tested and production-ready as documented.
