stackless-sdk (Python)

Python SDK for stackless. Published as stackless-sdk on PyPI (import stackless). Speaks the JSON protocol (../PROTOCOL.md) via the stackless CLI.

The PyPI distribution is stackless-sdk; the import package remains stackless.

Editable (from this repo):

pip install -e "sdks/python[dev]"

Usage

from stackless import Client, Create, Resume

client = Client.system()
out = client.up(Create(on="local", file="stackless.toml", name="demo"))
print(out.origins["web"])
print(out.integrations.get("clerk", {}))
client.down("demo")

Secrets

up returns secret references scoped to the immutable instance ID. Inject credentials into service or verify environments with ${integrations.<name>.<output>}. The controller redacts known secrets from returned logs and errors.

Tests

cd sdks/python && python -m pytest

Named endpoint bindings are in out.endpoints. Each entry has workload, url, and source (provider or declared). out.endpoint_urls supplies the map accepted by generated bind_endpoints. Declared URLs are unverified. TCP workloads return tcp://host:port; endpoint URLs do not imply HTTP support.

Resolved hosting providers are in outcome.placements.workloads and the corresponding resources map. The top-level substrate is the default; individual workloads and resources can select other providers with on.
