It is indexed under Web Frameworks.","source":"https://micronaut.io/","question":"What is Micronaut?","confidence":0.6},{"answer":"Micronaut is open source, so it can be self-hosted and used at no licence cost. It is released under the Apache-2.0 licence. Pricing changes often, so verify at source before relying on it.","source":"https://micronaut.io/","question":"Is Micronaut free to use?","confidence":0.6},{"answer":"Micronaut supports a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.","source":"https://micronaut.io/","question":"What platforms does Micronaut support?","confidence":0.6},{"answer":"We have only confirmed a cloud / SaaS deployment for Micronaut, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.","source":"https://micronaut.io/","question":"Can Micronaut be self-hosted?","confidence":0.6},{"answer":"We have confirmed 19 integrations for Micronaut, including GraalVM, Netty, Jackson, Gradle, RabbitMQ, gRPC, Consul and Eureka, plus 11 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.","source":"https://micronaut.io/","question":"What does Micronaut integrate with?","confidence":0.6},{"answer":"Yes. Micronaut is published under the Apache-2.0 licence, a permissive licence that generally allows commercial use and modification.
