Markdown Is Production Code: Why We Built Zenzic

Markdown Is Production Code: Why We Built Zenzic

We built Zenzic because we kept seeing the same problem: a documentation repository could be technically “green” while the documentation itself was already broken.

A build can succeed while an internal link points to a file that no longer exists. A page can remain in the repository while no navigation path reaches it. An anchor can become invalid after a heading is renamed. An image can disappear while the Markdown still references it. A code example can contain a live credential that gets copied into a public repository.

The build can still pass.

The deployment can still complete.

The defect is discovered only when a user follows the broken path—or when an exposed credential is abused.

We decided that this was the wrong model.

We built Zenzic to treat documentation integrity as a property that can be tested before a change reaches the main branch.

10 Documentation Bugs Caught by Zenzic

Documentation isn't just text — it's a critical interface. When users rely on your docs to deploy infrastructure, configure security policies, or integrate APIs, a "simple typo" can lead to hours of lost productivity.

In a docs-as-code workflow, documentation is code. And just like code, it has bugs. That's why we built Zenzic: a Deterministic Document Integrity Engine for Markdown/MDX graphs.

Here are 10 subtle, frustrating, and downright dangerous documentation bugs that Zenzic catches automatically in your CI/CD pipelines.
