Fern · FinOps Profile

Fern Api Finops

FinOps view of Fern spend. Fern is open-core: the `fern` CLI and code generators are open source (Apache-2.0), so running SDK and docs generation in your own CI/CD carries only your compute cost with no vendor invoice. The hosted Docs and SDK product is a SaaS subscription billed per plan - Hobby (free), Team (flat monthly, billed yearly), and Enterprise (custom) - with the AI documentation features (Ask Fern) metered against a monthly AI-credit allowance included in each plan. The dominant Fern-invoiced cost is the subscription tier plus any Enterprise add-ons (self-hosting, SSO, support).

Fern Api Finops is the FinOps profile for Fern on the APIs.io network, aligned with the FinOps Foundation Framework.
