| content.faq | `[{"answer":"CircleCI is a cloud-based continuous integration and continuous deployment (CI/CD) platform that automates the testing, building, and deployment of software projects. It integrates with version control systems to automatically run configured workflows whenever code is pushed or pull requests are created.","source":"https://circleci.com","question":"What is CircleCI?","confidence":0.95},{"answer":"CircleCI supports all major programming languages and frameworks, including Python, JavaScript/Node.js, Java, Go, Ruby, PHP, and Rust. Language support is achieved through Docker containers, allowing teams to define any custom environment needed for their builds and tests.","source":"https://circleci.com/docs","question":"What programming languages and platforms does CircleCI support?","confidence":0.92},{"answer":"CircleCI offers a free tier for open-source projects and individual developers with limited monthly compute credits. Paid subscription plans scale based on resource usage and organization members, with per-pipeline-run pricing models rather than per-project fees.","source":"https://circleci.com/pricing","question":"How is CircleCI priced?","confidence":0.88},{"answer":"Orbs are reusable, shareable packages of CircleCI configuration that bundle commands, jobs, and workflows to reduce duplication across projects. They accelerate setup for common integrations like deploying to cloud providers, running popular testing frameworks, or performing security scanning.","source":"https://circleci.com/docs","question":"What are CircleCI orbs and what can they do?","confidence":0.91},{"answer":"CircleCI provides self-hosted runners that execute jobs on a team's own infrastructure while maintaining centralized CI/CD orchestration through the cloud platform. This option addresses requirements around data residency, network isolation, or specialized compute environments.","source":"https://circleci.com/docs","question":"Does CircleCI offer self-hosted deployment options?","confidence":0.9},{"answer":"CircleCI natively integrates with GitHub, GitLab, and Bitbucket, using OAuth-based authentication to connect accounts and manage repository permissions. Workflows are automatically triggered by push events and pull request activities on these platforms.","source":"https://circleci.com/docs","question":"Which version control systems does CircleCI integrate with?","confidence":0.93},{"answer":"Yes, CircleCI supports both test parallelization and job-level parallelization, allowing test suites to run across multiple containers simultaneously. The platform also provides caching for dependencies and build artifacts to reduce redundant work across pipeline runs.","source":"https://circleci.com/docs","question":"Can CircleCI parallelize tests and jobs to speed up builds?","confidence":0.92},{"answer":"Competing CI/CD platforms include GitHub Actions, GitLab CI/CD, Jenkins, Travis CI, AWS CodePipeline, and JetBrains TeamCity. Selection typically depends on existing toolchain integration, deployment targets, compliance requirements, and organizational preferences.","source":"https://circleci.com","question":"What are the main alternatives to CircleCI?","confidence":0.89}]` | `[{"answer":"A platform that replaces shell scripts and YAML configurations with code-based pipelines. Runs identically on local machines and in CI/cloud environments, with built-in observability through OpenTelemetry traces and automatic content-addressed caching. It is indexed under CI/CD Tools.","source":"https://dagger.io/blog/new-dagger-cloud-pricing","question":"What is Dagger?","confidence":0.6},{"answer":"Dagger is open source, so it can be self-hosted and used at no licence cost. It is released under the Apache-2.0 licence. A commercial or hosted edition starts at $50 per month. Prices are published openly on the vendor's own pricing page. Pricing changes often, so verify at source before relying on it.","source":"https://dagger.io/blog/new-dagger-cloud-pricing","question":"Is Dagger free to use?","confidence":0.6},{"answer":"Dagger supports the web and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.","source":"https://dagger.io/blog/new-dagger-cloud-pricing","question":"What platforms does Dagger support?","confidence":0.6},{"answer":"Yes. Dagger can be deployed cloud / SaaS, on-premise and self-hosted, so it does not have to run on the vendor's infrastructure.","source":"https://dagger.io/blog/new-dagger-cloud-pricing","question":"Can Dagger be self-hosted?","confidence":0.6},{"answer":"We have confirmed 9 integrations for Dagger, including Docker, GitLab CI/CD, GitHub, Kubernetes, Terragrunt, Istio, Jaeger and Honeycomb, plus 1 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.","source":"https://dagger.io/blog/new-dagger-cloud-pricing","question":"What does Dagger integrate with?","confidence":0.6},{"answer":"We have independently confirmed SOC 2 and GDPR for Dagger. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Dagger not holding them. Always confirm compliance directly before you rely on it.","source":"https://trust.dagger.io","question":"What security certifications does Dagger have?","confidence":0.7},{"answer":"Yes. Dagger is published under the Apache-2.0 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/dagger/dagger","question":"Is Dagger open source?","confidence":0.95}]` |
