Pro and Enterprise feature

This feature is available only for the Pro and Enterprise plans. To get started, reach out to support@buildwithfern.com.

Use audiences to generate tailored SDKs for different groups of API consumers, such as internal teams, beta testers, or customers.

Audiences work through tag-based filtering: you tag API elements with audience labels in your spec, then configure which audiences to include when generating SDKs in generators.yml. For OpenAPI, path-based filtering is also available.

Get started with audiences

For complete instructions, see Audiences in OpenAPI — tag elements using x-fern-audiences, then configure SDK filtering in generators.yml.
