Timeline

Timeline is a free and open-source editor for creating, exploring, and sharing interactive chronological timelines. It allows users to add and edit events, periods, and eras with images, descriptions, and links. Timelines are stored in open .timeline files and can be exported as standalone HTML files that work offline. The editor runs entirely in a modern browser without requiring installation or internet connection, supporting offline usage and privacy, and is available both online as a PWA and as a single-file HTML download.
