Decision gist · record as of 2026-08-14
Yes, if you need programmatic access to Label Studio. The package is actively maintained, has low install friction, and supports current Python versions. However, verify the license terms before use—the metadata does not declare a license, which is a gap you should resolve before integrating into production or proprietary systems.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later (supports up to 3.15).
- Requires a running Label Studio instance and valid API credentials.
- Low friction installation with a pure Python wheel.

What it is and what it does
label-studio-sdk is a Python client library that wraps the Label Studio API, allowing developers to create, manage, and interact with annotation projects, tasks, and labels programmatically. It ships with both a Python API (instantiate a LabelStudio client and call methods like projects.create, tasks.create, projects.import_tasks) and a command-line interface that mirrors the SDK's resource structure.
The package is actively maintained and recently released version 2.0.0 with breaking changes and expanded feature support. It depends on a substantial set of runtime libraries including httpx and requests for HTTP communication, pydantic for data validation, and data processing tools like pandas, numpy, and opencv-python-headless. The library requires Python 3.10 or later and is distributed as a pure Python wheel, making installation straightforward across Windows, macOS, and Linux.
Use it for
- Automate bulk creation and import of annotation tasks into Label Studio projects from external data sources.
- Build a Python application that programmatically retrieves project statistics, task metadata, or annotation results.
- Integrate Label Studio workflows into data pipelines by using the CLI to manage projects and tasks without writing Python code.
- Validate label configurations and manage project settings programmatically before launching annotation campaigns.
- Sync annotation data between Label Studio and external systems via the SDK's API methods.
