Free-threaded Python 3.14 (python3.14t) and Node 22+. The feed records the whole market, whose opening auction changes thousands of books within seconds, by reading, parsing and writing on several cores at once, which Python does only without the GIL (a Python with it works, but warns that it can fall behind at the open). BRiSK's own decoder is a WebAssembly module that runs under Node.

pip install 'briskapi[pandas]'      # `import briskapi` and the `brisk` command

BRiSK's decoder and demo data are downloaded at runtime; the package doesn't include them. Optional prebuilt Rust tools (brisk_quote_ingest, brisk_recording) for Linux, macOS and Windows are attached to each GitHub release. To work from source, clone the repository and run pip install -e '.[pandas]'.
