Who is Userbook for?: It’s for devs, product teams, indie hackers and startups who don't want to write docs.
Does it work with any project structure?: Yes. Whether you use MVC, clean architecture, or something custom, we detect and group related files intelligently — no need to follow a strict pattern.
Is this different to Swagger?: Yes, with Swagger you have to manually write the docs. With Userbook, you can generate swagger documentation from code.
Can I edit the docs?: Yes. You can edit the docs directly in the UI.
How do my docs stay updated?: We auto-update your docs with every commit. You can also manually update them.
Can I export the docs?: Yes. Please contact support for a csv or JSON export.
What languages and frameworks does it support?: We currently all major web development languages and frameworks.
Is my code safe?: Yes. We use industry-standard security measures to protect your data. We use an LLM to process your code and never store it. We never sell your data. We never ask for write permission to your repo.
Do you store my code?: No, Userbook only stores the file tree and filenames, not the codebase. When generating docs the code from the connected Github repo is used.
