HumanSignal/label-studio
Label Studio is a multi-type data labeling and annotation tool with standardized output format
Supports active learning workflows by integrating ML models for automated pre-labeling and interactive predictions through a backend service API. Built on Django with a React frontend, it offers flexible storage backends (SQLite, PostgreSQL, S3/MinIO) and exports annotations in framework-specific formats for direct use in ML pipelines.
