Dynatrace OpenFeature Provider for Python

The official Dynatrace OpenFeature provider for Python server-side applications.

The provider evaluates flags in-process: on initialization it fetches your flag configuration from the Dynatrace CDN and refreshes it in the background, so evaluations are local and do not make a network call.

Status: Early alpha — not yet ready for production use.

Installation

pip install dynatrace-openfeature-provider-python

Usage

from openfeature import api
from openfeature.evaluation_context import EvaluationContext

from dynatrace.openfeature import DynatraceProvider

api.set_provider(DynatraceProvider("dt01.server_us_<key>"))

client = api.get_client()
ctx = EvaluationContext(targeting_key="user-123")
enabled = client.get_boolean_value("my-flag", False, ctx)

# On shutdown:
api.shutdown()

Once the provider is registered, all flag evaluation goes through the OpenFeature API. See the OpenFeature Python SDK documentation for evaluation contexts, hooks, events, and the rest of the SDK surface.

Configuration

Pass options as keyword arguments to DynatraceProvider:

api.set_provider(
    DynatraceProvider(
        sdk_key,
        config_origin="https://cdn.eu.fm.dynatracelabs.com",
        metrics_origin="https://metrics.eu.fm.dynatracelabs.com",
    )
)

Option	Type	Default	Description
config_origin	str	derived from SDK key	Override the flag configuration origin.
metrics_origin	str	derived from SDK key	Override the evaluation metrics ingest origin.

Running the e2e tests

The shared provider test harness gherkin suite runs against its mock server in a container, so Docker is required:

uv run poe e2e

This initializes the fm-provider-test-harness submodule and runs the suite with pytest-bdd. Set SKIP_HARNESS_UPDATE=1 to keep a local harness checkout, and MOCKSERVER_IMAGE to use a locally built mock server image.
