react-image-annotation

A React library for adding annotations to images. Current stable version is 0.9.10 (last updated 2019). Release cadence is low; no active development since 2020. Supports customizable selectors (rectangle, point, oval) and full rendering control via render props. Key differentiator: provides both annotation creation (geometry) and metadata storage (data) with custom component slots. Requires React 16.3+ and prop-types. Alternative for newer versions or ESM-only environments may need to consider forks.
