Docs as code vs traditional documentation

There are two broad ways to run documentation. The traditional way keeps docs in a dedicated editor or wiki, separate from the code. The docs as code way keeps docs as plain text files in the same repository as the code, edited and reviewed with the same tools. This post compares them so you can pick the right fit.

What traditional documentation looks like

Traditional docs live in a tool built for writing, like a wiki, a knowledge base, or a WYSIWYG editor. Confluence and Notion are common examples. You write in a rich editor, click publish, and the page is live.

The strengths are approachability and speed. Anyone can edit without knowing git. Non-technical teammates, support staff, and product managers can all contribute. Publishing is instant.

The weakness is distance from the code. The docs live somewhere else, so they are easy to forget when the code changes. There is no diff tying a doc edit to the change that required it, and no review flow shared with engineering.

What docs as code looks like

Docs as code means your documentation is markdown or MDX files in your repository. You edit them in the same editor as your code, review them in pull requests, and publish them through a pipeline.

The strengths are version control and proximity. Every doc change has a history, an author, and a review. The docs sit next to the code they describe, so a developer changing a feature can change its docs in the same pull request. Docs platforms like GitBook, Mintlify, and ReadMe sync from git, so the published site follows your repository automatically.

The weakness is the barrier to entry. Contributors need to be comfortable with git and pull requests, which rules out some of your team.

Side by side

	Traditional	Docs as code
Where docs live	Separate editor or wiki	In the repository
Who can edit	Anyone	People comfortable with git
Version history	Limited	Full, per change
Tied to code changes	No	Yes
Publishing	Instant	Through a pipeline

Which should you choose?

Choose traditional docs if your writers are non-technical, your content is broad, and it does not track a codebase closely. Internal knowledge bases and company handbooks fit here.

Choose docs as code if you are documenting software, your team already lives in git, and you want doc changes reviewed like code changes. Developer and API docs fit here.

The upkeep problem is the same either way

Neither approach fixes the core issue, which is that docs go stale when the code changes. Docs as code makes the fix easier, because the docs are already in the repository where the code changes happen. That is what lets tools help.

For example, uptodate works because your docs are docs as code. It reads the code changes you merge to GitHub, finds the markdown pages a change made inaccurate, and opens a pull request with the edit. That only works when the docs live in git next to the code. It is one more reason the docs as code model wins for software teams: it puts your documentation somewhere a tool can actually keep it honest.

The short answer

Traditional docs are better for non-technical writers and broad content. Docs as code is better for software, because it ties docs to the code, adds real version history, and lets automation keep the pages accurate.
