Image Annotation And Labeling Interface

via “multi-modal annotation interface with configurable labeling templates”

Open-source multi-modal data labeling platform.

Unique: Uses declarative XML-based label configuration (LSF format) that decouples annotation UI from backend models, allowing non-developers to compose complex labeling interfaces by combining pre-built control types (Choices, TextArea, Polygon, etc.) without modifying code or database schemas.

vs others: More flexible than Prodigy's recipe-based approach because templates are composable and reusable across projects; simpler than building custom Labelbox workflows because no API integration required for common annotation types.
