This go library provides beautiful Cucumber HTML reports.
gocuke-html is a fork of gocure that has been customised to address certain problems and to add new features.
For example gocuke-html is intended to fully support the standard Cucumber Json file format.
Issues raised against gocure are not getting any attention, so I assume it is unmaintained.
Gocure appears to be a reimplentation of the UI design of the earlier NodeJS project Cucumber-Html-Reporter.
