Buildkite is a continuous integration and delivery platform that facilitates automation in software development and deployment processes. Its primary purpose is to enable teams to build, test, and deliver software efficiently and reliably. With Buildkite, developers can automate the process of building and testing their code every time changes are made, ensuring that new features and bug fixes are thoroughly validated before being deployed to production. The platform supports various automation capabilities, such as running automated tests, code linting, and integration with version control systems. Buildkite is particularly valuable for software developers, engineering teams, and DevOps professionals, as it streamlines the software development lifecycle and helps maintain a high level of code quality and deployment confidence.
