tatolab-stream

The Python SDK for Tatolab, which turns cameras, microphones, screens, models and your own code into realtime streams that browsers, other streams and AI agents can read.

Looking to get started? Install the Tatolab app first, not this package. tatolab-stream is the library you write streams with. It doesn't run them: the Tatolab runtime on your machine does, and it comes with the app.

  • macOS (Apple silicon, macOS 15 or later): brew install --cask tatolab/tap/tatolab, then open -a Tatolab
  • Linux (x86_64 with a Vulkan GPU): curl -fsSL https://get.tatolab.com/install.sh | sh

Then follow the Quickstart. tatolab new creates a project that already depends on this package, so you rarely pip install it yourself.

What it is

A stream is an ordinary Python project. You write nodes as Python classes and connect them in a function decorated @stream:

from tatolab.stream import CameraSource, DisplayWindow, StreamBuilder, stream

from nodes.inverting_effect import InvertingEffect


@stream
def main(stream_builder: StreamBuilder) -> None:
    camera = stream_builder.add(CameraSource)
    effect = stream_builder.add(InvertingEffect)
    window = stream_builder.add(DisplayWindow, config={"title": "Tatolab"})
    stream_builder.connect(camera.output("video"), effect.input("video_from_upstream"))
    stream_builder.connect(effect.output("video_to_downstream"), window.input("video"))
    stream_builder.expose(effect.output("video_to_downstream"))

tatolab dev runs it in the runtime. Each node runs in its own process, so one slow node never blocks another. An exposed output gets an address other streams, agents and browsers can read.

This package holds the authoring API (@stream, @node, StreamBuilder), typed classes for every built-in node (camera, display, microphone, speaker, H.264, H.265 and Opus codecs, MP4 recording, and more), and the protocols your nodes are handed at run time. It installs and imports without the runtime, with complete type hints, so your editor, type checker and unit tests work on any machine.

Add it to an existing project

uv add tatolab-stream

The runtime runs your nodes with the project's .venv/bin/python, so anything you install there your nodes can import. See Python SDK for details.

Supports CPython 3.10 to 3.13 (not the free-threaded builds).

Other packages

  • tatolab-webrtc: WHIP publish and WHEP play nodes.
  • tatolab on PyPI is a placeholder that installs nothing. Tatolab itself installs as an app, as above.
