Apicurio Registry vs BBC Consumer Contracts

Both stand on contract testing tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.

Apicurio Registry

Free plan APILinuxMac+3

Choose Apicurio Registry if you need an open-source registry for API designs and evolving data schemas, with Kafka integration and configurable storage. Teams should account for enabling authentication and authorization where needed, and should not use the in-memory quick-start server for production.

BBC Consumer Contracts

Free plan APISelf-hosted

Choose BBC Consumer Contracts if you need a free, self-hosted way to express consumer expectations as executable JavaScript API checks. Its request and Joi integrations cover response codes, headers, and JSON bodies, with both command-line and programmatic execution. Consider another option if your runtime does not meet the Node.js and pnpm requirements or you need a non-JavaScript contract format.
