I did some research here on Product Hunt but most of the nice ones are more for API documentation and kinda expensive.
- Today's knowledgebase/documentation for SaaS products is done using the same help desk software such as ZenDesk, FreshDesk, HelpScout, Desk.com etc. These products are great when it comes to ticketing/help desk capabilities but their self-service documentation comes with a lot of gaps. After facing challenges ourselves with these products for our product documentation, we decided to build Document360 focused specially towards SaaS product documentation. We wanted to focus mainly on SaaS products & Software projects. If you are interested, please sign up for the early beta access here: https://document360.io/. We are going for BETA mid April.
