What are Free Build Automation Tools?

Build automation tools are software tools that automate the process of compiling, testing, and deploying software applications. These tools help developers streamline the building of software from source code, ensuring that the process is repeatable, consistent, and efficient. Build automation typically includes compiling code, running unit tests, generating reports, packaging software, and deploying it to different environments. By automating these steps, build automation tools reduce human errors, improve efficiency, and support continuous integration and continuous delivery (CI/CD) practices.

    Automating your workflow can be achieved by using pipelines as they are the heart of the CI process in Microtica.

The build process is defined by a single source of truth, a microtica.yaml file in the root folder of the repository. With user customizability as a key feature, every user is able to define how their build process is done and what commands are ran by changing the microtica.yaml file.

    AWS CodeBuild
    AWS CodeBuild is a fully managed continuous integration service that compiles source code, runs tests, and produces software packages that are ready to deploy. With CodeBuild, you don’t need to provision, manage, and scale your own build servers. CodeBuild scales continuously and processes multiple builds concurrently, so your builds are not left waiting in a queue. You can get started quickly by using prepackaged build environments, or you can create custom build environments that use your own build tools. With CodeBuild, you are charged by the minute for the compute resources you use. With AWS CodeBuild, your build artifacts are encrypted with customer-specific keys that are managed by the AWS Key Management Service (KMS). CodeBuild is integrated with AWS Identity and Access Management (IAM), so you can assign user-specific permissions to your build projects. AWS CodeBuild belongs to a family of AWS Code Services.

    Buildkite

    Buildkite

    Buildkite

    Run the open-source buildkite-agent on your own infrastructure for maximum speed, control, and security. The agent checks out your source code, executes custom hooks and overrides, and then runs your build jobs. Your source code never leaves your infrastructure. You can install the agent using one of our packages and binaries for almost every platform and architecture, including Ubuntu, Debian, Mac, Windows, Docker, and more. The agent’s artifact and meta-data storage allows for share-nothing, state-free build jobs that can be easily distributed and scaled across any number of agents. Run as many build agents as you need (up to 10,000 connected per account), without breaking a sweat. The open-source Elastic CI Stack for AWS gives you an easy-to-maintain, elastically scaling CI stack in your own AWS account. Or if you prefer to roll your own, you can use the tools you’re already familiar with in your production environments (such as Packer and Terraform).
