In their own words
Gradle
Gradle Build Tool is a free, open-source system for automating software builds across projects of different types and sizes. Build logic can use either Kotlin DSL or Groovy DSL. Incremental builds, caching and parallel task execution support the build process, while Gradle downloads and manages transitive dependencies from Maven- and Ivy-compatible repositories. The Gradle Wrapper can provision a build environment and specify the Gradle version used by a project. Its ecosystem covers JVM, Android, C/C++, Swift, Objective-C and assembler projects, and it runs on Windows, macOS and Linux. The Tooling API lets IDEs and other tools inspect projects, run builds, receive progress events and cancel operations. Listed support includes Android Studio and Ant, plus Checkstyle, CodeNarc, PMD and JaCoCo. Gradle includes dependency verification. The maker says open-source security fixes are limited by its end-of-life policy; its Security Subscription offers prioritized fixes under SLA and extended maintenance, but does not guarantee a clean scanner report when findings come from third-party libraries.
Open Build Service
Open Build Service (OBS) builds and distributes binary packages from source code in a consistent, reproducible way. Each package is built in a fresh jailed environment; when a build succeeds, OBS rebuilds packages that depend on it. The service can release packages, updates, add-ons, appliances, and complete distributions for different operating systems and hardware architectures. Documented package formats include RPM, DEB, and Arch, with recipes in formats such as spec, dsc, KIWI, and mkosi. Teams can use access controls, branches, merge requests, and submission reviews to coordinate work. GitHub.com and GitLab.com integrations are supported, as are self-hosted GitHub, GitLab, and Gitea instances when network connectivity works. The API gives clients and external services access to OBS resources, while the osc command-line client can edit sources and metadata, start builds, and gather results. OBS is GPL-licensed free software, available on a reference server for open-source developers or for installation on users’ own hardware or in a data center. The listed plan is free.
