Probably want a async with wrapper that connects to the firehose and parses and stores the messages it receives, so that they can be checked for expected results afterwards. (will probably want to ...

Filling the remaining gap between WebSocket, WebRTC and WebTranspor
Existing web platform facilities for network communication include WebSocket and WebRTC. Each mandates a specific protocol, ensures TLS, and respects the Same Origin Policy. The proposed WebTransport is similar in these respects.
Spacedust | ATProto Notifications Firehose
A configurable ATProto notifications firehose. Consumes Jetstream, extracts links, exposes via WebSocket API.
mitmproxy - an interactive HTTPS proxy
mitmproxy is your swiss-army knife for debugging, testing, privacy measurements, and penetration testing. It can be used to intercept, inspect, modify and replay web traffic such as HTTP/1, HTTP/2, HTTP/3, WebSockets, or any other SSL/TLS-protected protocols. You can prettify and decode a variety of message types ranging from HTML to Protobuf, intercept specific messages on-the-fly, modify them before they reach their destination, and replay them to a client or server later on.

ATOM: AT Protocol Over MoQ Transport
This document specifies how the Authenticated Transfer (AT) Protocol can leverage Media over QUIC Transport (MOQT) for efficient data synchronization across decentralized social networks. The AT Protocol's firehose event stream and repository synchronization mechanisms map naturally to MOQT's publish/subscribe model, enabling scalable relay infrastructure, priority-based delivery, and improved resilience for large-scale social data distribution. This specification addresses the challenges of the current WebSocket- based transport and demonstrates how MOQT's relay architecture, group-based caching, and multiplexed streams provide significant benefits for AT Protocol deployments at scale.
runtime.sendNativeMessage() - Mozilla | MDN
Sends a single message from an extension to a native application.

fun new little websocket client published under @atproto/ws-client. works in the browser or server-side. designed for long-lived connections and reconnects. care taken with flow control and backpressure. because, you know... atproto go wsssshh. tangled.org/strings/did:plc:l3rouwludahu3…
We need to come up with some fun interactive experiments with the firehose. Seriously, back in 2013 Emojitracker was big news. Today, I asked Opus to create a clone and a couple minutes later: artifacts.vza.net/emojihose

The AI community is SLEEPING on atproto's potential. With all the "on-tap intelligence" we have these days you'd think they'd be faster to figure that out
