# splitio-client — Split.io Python Client

License: permissive · Maintenance: active · Downloads: 231.3K/mo

## What it is and what it does

The Split Python SDK is a client library for integrating Split's feature flag platform into Python applications. It allows developers to query feature flags at runtime to control which code paths execute for different users, enabling safe feature rollouts, A/B testing, and gradual deployment strategies without redeploying code.

The SDK works by instantiating a factory with your API credentials, waiting for it to become ready (with a configurable timeout), then retrieving a client to query treatments for specific users and feature flags. Each query returns a treatment value (typically 'on', 'off', or a control variant) that your application logic uses to decide behavior. It has no external runtime dependencies and is maintained by Split's team.

Use it for:

- Gradually roll out new features to a percentage of users before full release.
- Run A/B tests by assigning different user cohorts to different feature variants.
- Kill-switch a feature in production without redeploying code.
- Segment users by custom attributes to deliver different experiences.
- Manage feature flags across multiple environments from a centralized platform.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

A Python client SDK for integrating Split feature flags into applications to manage controlled feature rollouts and A/B testing.

Yes, if you are already using Split's platform or planning to adopt it for feature management. The SDK is actively maintained, has no external dependencies, and is permissively licensed. The high install friction is a concern but typical for enterprise SDKs; verify whether it affects your deployment workflow before committing.

## Install

pip install splitio-client
uv add splitio-client
poetry add splitio-client

## Installing splitio-client

Before you install: High install friction reported; no runtime dependencies to manage, but the package itself requires setup. Last release was 198 days ago and the repository is active, suggesting ongoing maintenance.

License in practice: Licensed under Apache License 2.0 (permissive), allowing broad use in commercial and open-source projects with minimal restrictions.

Quickstart:

pip install splitio-client

from splitio import get_factory
from splitio.exceptions import TimeoutException

factory = get_factory('YOUR_SDK_TYPE_API_KEY', config=config)
factory.block_until_ready(5)
split = factory.client()
treatment = split.get_treatment('CUSTOMER_ID', 'FEATURE_FLAG_NAME')

Requires a valid Split SDK API key and network connectivity to the Split platform; Python 3.7 or higher.

Verify before relying:

- Whether high install friction stems from compiled dependencies, large package size, or complex setup requirements.
- Current Python version support beyond the stated 3.7+ compatibility in the description.
