``tractor`` is a `structured concurrent`_, (optionally
distributed_) multi-processing_ runtime built on trio_.
``tractor`` is a `structured concurrency`_ (SC), multi-processing_ runtime built on trio_.
Fundamentally, ``tractor`` gives you parallelism via
``trio``-"*actors*": independent Python processes (aka
non-shared-memory threads) which maintain structured
concurrency (SC) *end-to-end* inside a *supervision tree*.
Fundamentally, ``tractor`` provides parallelism via
``trio``-"*actors*": independent Python **processes** (i.e.
*non-shared-memory threads*) which can schedule ``trio`` tasks whilst
maintaining *end-to-end SC* inside a *distributed supervision tree*.
Cross-process (and thus cross-host) SC is accomplished through the
combined use of our "actor nurseries_" and an "SC-transitive IPC
protocol" constructed on top of multiple Pythons each running a ``trio``
scheduled runtime - a call to ``trio.run()``.

We believe the system adheres to the `3 axioms`_ of an "`actor model`_"

Features
--------
- **It's just** a ``trio`` API
- *Infinitely nesteable* process trees
- Builtin IPC streaming APIs with task fan-out broadcasting
- A "native" multi-core debugger REPL using `pdbp`_ (a fork & fix of
`pdb++`_ thanks to @mdmintz!)
- Support for a swappable, OS specific, process spawning layer
- A modular transport stack, allowing for custom serialization (eg. with
`msgspec`_), communications protocols, and environment specific IPC
primitives
- Support for spawning process-level-SC, inter-loop one-to-one-task oriented
``asyncio`` actors via "infected ``asyncio``" mode
- `structured chadcurrency`_ from the ground up
- **It's just** a ``trio`` API!
- *Infinitely nesteable* process trees running embedded ``trio`` tasks.
- Swappable, OS-specific, process spawning via multiple backends.
- Modular IPC stack, allowing for custom interchange formats (eg.
as offered from `msgspec`_), varied transport protocols (TCP, RUDP,
QUIC, wireguard), and OS-env specific higher-perf primitives (UDS,
shm-ring-buffers).
- Optionally distributed_: all IPC and RPC APIs work over multi-host
transports the same as local.
- Builtin high-level streaming API that enables your app to easily
leverage the benefits of a "`cheap or nasty`_" `(un)protocol`_.
- A "native UX" around a multi-process safe debugger REPL using
`pdbp`_ (a fork & fix of `pdb++`_)
- "Infected ``asyncio``" mode: support for starting an actor's
runtime as a `guest`_ on the ``asyncio`` loop allowing us to
provide stringent SC-style ``trio.Task``-supervision around any
``asyncio.Task`` spawned via our ``tractor.to_asyncio`` APIs.
- A **very naive** and still very much work-in-progress inter-actor
`discovery`_ sys with plans to support multiple `modern protocol`_
approaches.
- Various ``trio`` extension APIs via ``tractor.trionics`` such as,
- task fan-out `broadcasting`_,
- multi-task-single-resource-caching and fan-out-to-multi
``__aenter__()`` APIs for ``@acm`` functions,
- (WIP) a ``TaskMngr``: one-cancels-one style nursery supervisor.
Install
-------
``tractor`` is still in a *alpha-near-beta-stage* for many
of its subsystems, however we are very close to having a stable
lowlevel runtime and API.
As such, it's currently recommended that you clone and install the
repo from source::
pip install git+git://github.com/goodboy/tractor.git
We use the very hip `uv`_ for project mgmt::
git clone https://github.com/goodboy/tractor.git
cd tractor
uv sync --dev
uv run python examples/rpc_bidir_streaming.py
Consider activating a virtual/project-env before starting to hack on
the code base::
# you could use plain ol' venvs
# https://docs.astral.sh/uv/pip/environments/
uv venv tractor_py313 --python 3.13
# but @goodboy prefers the more explicit (and shell agnostic)
# https://docs.astral.sh/uv/configuration/environment/#uv_project_environment
UV_PROJECT_ENVIRONMENT="tractor_py313
# hint hint, enter @goodboy's fave shell B)
uv run --dev xonsh
Alongside all this we ofc offer "releases" on PyPi::
pip install tractor
Just note that YMMV since the main git branch is often much further
ahead then any latest release.
Example codez

In ``tractor``'s (very lacking) documention we prefer to point to
example scripts in the repo over duplicating them in docs, but with
that in mind here are some definitive snippets to try and hook you
