A wiki you write vs. docs that write themselves
GitBook is at heart a collaborative editor: spaces, pages, comments, change requests, a WYSIWYG surface non-engineers can use. Its Git Sync can mirror content to and from a repository, which keeps GitBook and Git *in agreement with each other* — but the content still only changes when a person edits it.
Pushpen inverts the direction of truth. The code is the source; documentation is derived from it. When you push, Pushpen reads the diff and proposes updated docs as a pull request. Nobody drafts anything. That makes Pushpen a poor fit for the things wikis are great at — product specs, meeting notes, policies, anything with no code to derive from — and a strong fit for the code-shaped docs that GitBook pages quietly drift away from.
The practical split we see: knowledge that originates in people's heads belongs in a wiki like GitBook; knowledge that originates in the codebase (setup steps, API surface, what changed this release) is exactly what should be generated, because human maintenance of it reliably falls behind.
Per-seat vs. per-repo economics
GitBook prices per user, which is fair for an editing product — its value scales with writers. Pushpen prices by plan with repository and generation limits, because its value scales with how much code motion it documents. A 15-person team that mostly *reads* docs pays for 15 GitBook seats; the same team on Pushpen pays for the repos being documented, regardless of team size on Free/Starter/Pro, or a flat Teams plan with 10 seats for shared repos.

- You need a public docs site with custom branding
Switching from GitBook — or using both
Teams rarely need to rip out a wiki. What actually works:
- →Leave people-authored content (specs, processes, product docs) in GitBook. Add Pushpen so the code-derived documents — README, changelog, API docs, onboarding — regenerate on every push instead of rotting in a space nobody reopens.
- →If GitBook's Git Sync already mirrors your docs into the repo, Pushpen's PRs flow back through that same sync — you keep GitBook as the reading surface while Pushpen does the updating.
- →Moving off GitBook entirely: export spaces to markdown, commit them, and let plain GitHub rendering serve them. Pushpen then maintains the code-shaped subset automatically; the rest you edit as normal files.
Frequently asked questions
Is Pushpen a replacement for GitBook?+
Only for the code-derived part of your docs. Pushpen generates and maintains README, changelog, API docs, and onboarding guides from your pushes. It is not a wiki — product specs, processes, and people-authored pages still belong in a tool like GitBook or a repo folder you edit by hand.
Can Pushpen work alongside GitBook's Git Sync?+
Yes. Pushpen writes to your repository through pull requests. If GitBook mirrors that repository, merged Pushpen updates appear in GitBook like any other commit.
Why is GitBook per-seat and Pushpen per-plan?+
GitBook is an editing product, so it charges per writer. Pushpen automates the writing itself, so it charges by plan based on repositories and generation volume — team size does not change the price on individual plans.
