It is indexed under API Mocking.","source":"https://github.com/pricing","question":"What is Nock?","confidence":0.6},{"answer":"Nock is open source, so it can be self-hosted and used at no licence cost. It is released under the MIT licence. Pricing changes often, so verify at source before relying on it.","source":"https://github.com/pricing","question":"Is Nock free to use?","confidence":0.6},{"answer":"Yes. Nock is published under the MIT licence, a permissive licence that generally allows commercial use and modification. Licence terms can change between releases, so verify against the repository for the version you intend to use.","source":"https://github.com/nock/nock","question":"Is Nock open source?","confidence":0.95}]` | `[{"answer":"An open-source platform that lets developers build mock APIs for testing applications in isolation. It records interactions with real services for replay, creates stateful mock scenarios, supports fault injection, and tests multiple protocols, enabling faster and safer development cycles.
