CARTO and CARTO Builder
CARTO Builder is cloud-based mapping software that does not require knowledge of code. Georectified historical maps may be used as basemaps.
You can sign up for this platform using the Github school pack or just sign up on their website. If you use your '.edu' email to gain access, it allows extra functionalities.
CARTO is transitioning to a new platform, CARTO Builder.
