Question 1

Zally vs Spectral: which is better for OpenAPI linting?

Accepted Answer

Zally is more focused on enforcing RESTful design guidelines with customizable rules via Java/Kotlin, while Spectral offers broader JSON Schema support and a larger ecosystem. Zally excels for organizational standards, but Spectral is more flexible for general validation.

Question 2

How to integrate Zally into a CI/CD pipeline?

Accepted Answer

Use the CLI or REST API to run Zally in CI scripts, such as invoking the Docker container to validate OpenAPI specs at build time. The unofficial Maven plugin can also be added for Java projects to automate checks.

Question 3

Can Zally be used with GitHub Actions?

Accepted Answer

Yes, but it requires custom setup since there's no official action. You can run Zally via Docker in a GitHub Actions workflow, pulling the image and executing checks against your API specifications.

Question 4

What are the performance implications for large API specs?

Accepted Answer

Performance depends on server resources and spec size; Zally handles typical APIs efficiently, but very large specs with numerous rules may slow down. It's recommended to test with your specific data to gauge impact.

Question 5

How to ignore specific checks in Zally using x-zally-ignore?

Accepted Answer

Add the x-zally-ignore extension to your OpenAPI spec with a list of rule IDs to exclude, allowing targeted bypass of checks. This is useful for legacy code or temporary exceptions without disabling all validation.
