Cosign Plans Pricing
Cosign publishes no plans and no pricing, and this is not an omission — it is an Apache-2.0 open source project of the OpenSSF, and the Sigstore public-good instance it talks to is free to use for everyone with no account, no key and no billing relationship. There is no signup, no paid tier and no enterprise "contact us" form. This file replaces a 2026-05-04 bulk-sweep scaffold that invented a "Free" tier with an "API Requests" quota; no such tier or quota exists.
Cosign Plans Pricing is the pricing profile for Cosign on the APIs.io network.
