WebRTC-powered video calling application with screen sharing, audio controls, and real-time communication.
Single-purpose pages, each one live. Open any of them in two tabs and the tabs meet in the same channel.
The published JavaScript SDK driven end to end: channels, presence, history and chunked transfer.
Publish messages, then read them back out of the shared store rather than a local buffer.
Round-trip latency measured by token correlation, with throughput derived from real completions.
Key scoping, channel isolation and authorisation behaviour, exercised against the live platform.
Fan real-time events out to downstream systems and watch the deliveries land.
Every documented call, runnable in the page, returning the platform's actual response.
The code you would write in each language, alongside buttons that run the same operations live and print the measurements.
CPython in the browser via Pyodide, driving a genuine socket — await channel.publish() puts a frame on the wire.
Worker-pool bursts and a latency distribution, both computed from traffic this page actually sent.
Connection, channel messaging, broadcast envelopes and presence, each one a measured round trip.
Chat, presence roster, notifications, chunked upload and a real offline queue that flushes on reconnect.
