Docup vs ReadMe
How Docup and ReadMe compare: documentation from a repository versus an API documentation platform built around OpenAPI, and what each costs.
On this page
The short version
ReadMe describes itself as a documentation platform for API docs. It builds an API reference from an OpenAPI spec and syncs with GitHub and GitLab. Docup reads a whole repository, plans the pages the project needs and writes them, then keeps them current as the code changes.
What we say about ReadMe comes from its official site on November 3, 2026. It can change, so check readme.com and its pricing page for the current details.
What ReadMe says it offers
- A dynamic API reference generated from an uploaded OpenAPI spec, with code samples and auth handling.
- A browser editor, an IDE workflow, and Git sync with GitHub, GitHub Enterprise Server and GitLab.
- An AI Writer that drafts doc updates from pull requests and Slack threads onto a review branch, an AI linter and style guides, and an MCP server for agents.
- A free Starter plan, Pro at $250 per month billed annually, and Enterprise on request. Its site notes some AI features are in beta on Pro and higher.
Where Docup fits
- You want guides, getting started and concept pages, not only an API reference.
- Your project has no OpenAPI spec, or the docs should come from the code itself.
- You want read-only access and a private draft you review before anything is public.
- You want to pay nothing during early access.
Where ReadMe may fit better
- Your product is an API and developers need an interactive, spec-driven reference.
- You need the extras ReadMe lists, such as style-guide checks and an MCP server for agents.
Frequently asked questions
- Is Docup an alternative to ReadMe?
- For project and developer documentation, yes. If your main need is an interactive API reference built from an OpenAPI spec, ReadMe is designed for that.
- Does ReadMe have a free plan?
- Its pricing page lists a Starter plan at $0 per month. Check readme.com for current terms.
- Does Docup need an OpenAPI spec?
- No. Docup reads the files of your repository and writes the pages from them.
