What is Label Studio?

Label Studio is a web app for annotating data such as classifying text, drawing boxes on images or transcribing audio. Teams use it to build training sets and to review or evaluate LLM outputs, and it can connect to ML back-ends for pre-labeling.

Where it fits in a 10–200 person business

  • Build a labelled dataset of support tickets to fine-tune or evaluate a classifier
  • Human review of LLM answers before rolling out an assistant
  • Annotate product images for a visual search model

These use cases are our editorial suggestions, not claims made by the project.

Known gotchas when self-hosting Label Studio

  • The quick-start container keeps its SQLite database and uploads in ./mydata, so back up that folder. PostgreSQL 14+ is supported, for example via the Docker Compose setup. source
