GitBook pricing explained

How much does GitBook cost?

Prices from GitBook's pricing page, checked 2026-10-06, with yearly billing.

What does a small team pay?

GitBook's bill is sites times plan price, plus users times $12/user/mo.

A second public site, such as separate docs for two products, doubles the site fee.

How do GitBook's AI credits work?

Paid plans include a monthly AI credit allowance ($20 on Essential, $100 on Ultimate) used by features like the AI Assistant and the GitBook Agent. Essential's Assistant gives short answers; full chat and AI insights are on Ultimate. Check how quickly your readers' questions use the allowance in the first month.

Which plan should you choose?

Free works for a personal or internal project without a custom domain. Essential is the usual starting point for public product docs on your own domain. Ultimate is for teams that need authenticated docs, a custom subdirectory like yoursite.com/docs, adaptive content, or AI chat for readers.

What isn't included?

GitBook is a docs platform, not a helpdesk: there's no shared inbox or ticketing. Like other docs platforms, keeping articles current after each release is your team's job; GitBook's Agent helps write and edit, and Git sync helps engineers update docs alongside code.

How do costs grow as you scale?

GitBook's costs grow along two lines: sites and users. Adding writers costs $12/user/mo each, which stays modest. Adding sites, such as separate docs for a second product or a separate developer portal, adds the full site fee each time. Moving to Ultimate for authenticated docs or AI chat multiplies the site fee by almost four. Map out how many sites and writers you expect in a year before choosing a plan.

How does GitBook compare with other docs tools?

GitBook is often the cheapest paid option for a small team with one public site.

Which GitBook features cost extra?

Beyond sites and users, the main variable is AI. Essential's included $20 of credits covers light use of the AI Assistant and the GitBook Agent; heavier use, or AI Assistant chat, points toward Ultimate. Authenticated docs for logged in customers, a custom subdirectory like yoursite.com/docs, and adaptive content are Ultimate features too, so a requirement like private customer docs can move you up a plan on its own.

Which GitBook plan fits?

What are the alternatives?

For developer docs, Mintlify (free Starter, Pro $450/mo billed yearly) and ReadMe (free Starter, Pro $250/mo billed yearly) are common alternatives; GitBook vs Mintlify compares the first. For a customer help center, usedocs is one plan at $99/mo with 5 seats, a custom domain, an assistant with 2,000 AI conversations, and edits proposed from your merged pull requests.
