Zero-dependency Python script to decode the Bluesky Firehose

This is a pure Python implementation of code necessary to decode the Bluesky Firehose's low-level binary data format.

It does not depend on any third-party libraries for decoding; we implement DAG_CBOR and CARv1 decoding ourselves.

To run this, install Astral's UV.

Then:

This small Python script makes it easy to convert from ATProto DIDs to their associated handles and back again:

$ ./resolve.py handle @davepeck.org
did:plc:caznr5mgvjft4mu4p2vpttfx
$ ./resolve.py did did:plc:caznr5mgvjft4mu4p2vpttfx
davepeck.org

Connect to the Bluesky Jetstream, emitting one JSON line per message received.

To use, make sure you have Astral's UV installed.

Then, run it as:

$ uv run https://gist.githubusercontent.com/davepeck/5484fc026a2e8269cf1ead00fff0ef8f/raw/ab4b06145d01f16c216ca3135da2945abdaf0010/jetstream.py

It's pretty simple. Example usage:

>  python3 wordle.py
