Label Studio

Label Studio is an open data labeling platform for audio, text, images, video, and time series. It provides configurable labeling interfaces, project management, model-in-the-loop pre-labeling with an external inference backend, and export to common training formats. Deployable via pip, Docker, or Docker Compose and self-hostable. The OSS edition is complemented by a paid cloud and enterprise tier from HumanSignal.
