eniston Knowledge Bases is a simple hosted knowledge base for startups, internal teams, and support teams: it creates customer-facing help centers and internal documentation with an article editor, categories, tags, related articles, themes, custom category icons, customer feedback, and instant search, without charging per user.
The AppSumo deal is a single lifetime tier: $79 once against a $1,080 original price, mapped to the Business plan with up to 10 workspaces (extendable), unlimited categories, articles, and users, a custom domain with SSL, custom CSS, IP restriction, password protection, frontend authorization, team management, and read-only API access. The code must be redeemed within 60 days of purchase, and all future plan updates are included. No yearly regular price for the exact Business mapping is stated here, because the vendor pricing page does not publish one in fetchable text.
AppSumo shows 182 reviews averaging 4.95 out of 5 (174 five-star, 6 four-star, 2 three-star, none lower), and recent reviews from July to October 2026 are all five-star.
