Project Mirador


Launched: 2013
Record Updated: Apr 18, 2024
Annotations system
Media viewer/player
Mirador is a configurable, extensible, and easy-to-integrate image viewer, which enables image annotation and comparison of images from repositories dispersed around the world. Mirador has been optimized to display resources from repositories that support the International Image Interoperability Framework (IIIF) API's. Mirador provides several workspaces for comparing image-based resources, suitable for use in both cultural heritage and research settings.


Mirador is an open-source, web based, multi-window image viewing platform with the ability to zoom, display, compare and annotate images from around the world.

Key Achievements

As of Summer 2023, Mirador community members are focused on updating core dependencies and related tests, which includes upgrading to the latest versions of React and Material UI. Updating Mirador’s core has been the highest priority for the community since February and will continue to be for the months to come, as it will resolve a number of known issues and unblock plugin development.

You can follow day-to-day progress on this work through the activity in Mirador’s project repository on GitHub, or get informed at a broader level by visiting the project milestones doc. We’d be thrilled for you to join the effort! Please reach out to the community through the channels listed above if you wish to learn more about where and how to help.
