Best offline API documentation

[smprk]

I recently wanted to access all Ansible documentation offline and did that using this - https://github.com/ansible/ansible/tree/devel/docsite

Next day a colleague and friend shared this app, and I must say it is the best offline documentation app out there - https://kapeli.com/dash

I would be interested in finding out if there are more such utilities and how they compare. This one is super awesome...!
