What is Label Studio?
Open-source data labelling for any modality.
Who is Label Studio best for?
Label Studio is best for machine learning teams that label training or evaluation data on their own servers.
Computer vision datasets
Boxes, polygons, keypoints, segmentation and frame-by-frame video tracking cover most image and video labeling jobs.
LLM and agent evaluation
Rubrics, side-by-side comparisons and turn-by-turn review let people grade model answers and agent traces.
Teams that keep data in-house
The Community Edition runs on your own servers, and Enterprise can run on-premises with SOC 2 and HIPAA reporting.
Labeling inside an ML pipeline
An API, Python SDK and webhooks connect your models for pre-labeling and send finished labels back into training.
