The best knowledge base and help centre software for lean B2B founders

We compared all six published tools in our Knowledge base and help centre catalogue, scored on the data we hold for each: starting price, free option, and four capability flags (public help centre, internal wiki, AI search and answers, custom domain and branding). Scores weight what a lean B2B founder feels first, a branded customer-facing help centre and an honest price, over enterprise depth. Pricing reflects publicly listed figures as of June 2026; quote-only vendors are penalised on transparency, because a price you have to phone for is rarely a price built for a small team. Honesty over affiliate incentive: where a cheaper or freer tool does the job, it ranks above a pricier one regardless of who pays us.
