Why Not Just Use a Hosted Knowledge Base?
Everything a hosted knowledge base does - without the monthly bill.
Hosted KB platforms are great software. But if your site runs on WordPress, you’re paying every month to rent a knowledge base you could own - on your own domain.
Hosted KB pricing varies widely by vendor, plan, and team size; figures are typical annual ranges for a small team. Actual pricing varies.
If you want a fully hosted platform with no WordPress site, a SaaS KB is the right tool. If your site runs on WordPress, Heroic KB does the same job on your own domain - for one flat annual fee.

Heroic KB is part of the HeroThemes family - trusted for support and documentation by teams worldwide.
“We used the KnowAll Theme to develop a Learning Knowledge Center. This Knowledge center assists our learning community by providing information on industry terminology, training programs, user guides, and much more. Our users regularly comment on the polished user experience of the theme and our admins enjoy the simplistic tools for managing the information and the analytic tools are also a plus. We would not ask to change much to the theme but if we could make one recommendation it would be to allow duplication of articles or article templates. Our team and users appreciate this tool and we would recommend it to anyone looking for a low maintenance solution for providing information and support to their customers. Thank you for a great product and your customer support is great too!”
“Love KnowAll – it has been a great move for us… it looks great, is easy to use and ensures our customers have everything they need in one place.”
“Plugin works great so far. Extremely easy to implement and install. Easy to use, very clean design, robust tracking features. All for a flat fee. Great support documentation, Solid value.”
“I love it. It gives you everything you need for your knowledge base without any hassle. Setting it up is very easy and I love the sidebar function that automatically creates a navigation.”
“I bought the KnowAll Theme and I was amazed and how fast I had a fully-functional, good-looking documentation website. I would definitely buy again!”
“At Pagely we set up the HeroThemes the KnowAll theme as a pre-sales KB for people evaluating our managed WP hosting service. Initially we had intended to run this as an internal-facing tool to be used exclusively by our sales team. The idea was to make the KB into the authoritative hub for all pre-sales questions. Training would consist of having new salespeople self-educate about our service by combing through KB articles then listening to recent calls, reading sales exchanges and internal chats and then updating that info in the KB. Midway through this process of setting this up we realized with extra work we could externalize the resource and transform it into a self-serve resource that could be used by prospects as well as salespeople. We put our interns on the task of extracting & sanitizing Q&A from the aforementioned channels. To date have over 400 discreet question & answer pairs from past sales exchanges. We added a livechat widget to the KB site for leadgen and as a mechanism to answer questions not currently addressed by the KB. In all the KB has been a great asset to the Pagely sales process. The type-ahead search feature provides a fast way to filter by keyword and the categorical organization gives a simple means to browse by topic area. Backend reports show us which articles are unclear and need refinement. Having it indexed by Google gives us long-tail SEO benefits. And most importantly we now have a scaleable way to onboard our new salespeople. The KB allows us to preserve tribal sales knowledge and exposes it in a way that teaches salespeople and also accommodates prospects who prefer to get their answers self-serve. We're happy customers of HeroThemes and endorse both the product and the support we've seen from the company.”
“So far, this theme has been incredible! it was super easy to set up, and when i did need a question answered, support was super quick and friendly! the theme has everything we needed 🙂”
“This took a LOT of work off my plate – their KB skin is incredible and has all the functions our 1200 employee business needed. Thanks!”
“Appearance options easily displayed in the backend could help us even more, mainly in the table of contents from articles.”
“The folks at HeroThemes have done a really good job. This theme works very well and it contains all the functions you need to build a quality knowledge base.”
