It offers reliability, resource efficiency, and enterprise-grade security. Alpaquita is distinguished by multiple performance and security optimizations and LTS releases optimal for enterprise use. Alpaquita comes with three additional malloc for various workloads and best Java support. In addition, we enhanced stock musl libc. Our musl perf is similar or superior to glibc performance. We also provide two Alpaquita variants based on musl perf or glibc. Alpaquita Stream is a free rolling release of Alpaquita with the latest updates and fixes. Alpaquita LTS is a stable version supported for four years with two-years overlap with the previous version. Alpaquita comes in two versions, musl and glibc-based. Our musl perf is 100% compatible with musl def (a default musl implementation similar to the upstream release version), but boasts performance enhancements making it as efficient as glibc. The process of migrating to Alpaquita depends on several factors, such as libraries utilized for development (statically or dynamically linked) and so on. If you build an application outside Docker and copy the binary into the Docker image, simply substitute the image you are currently using. Security and updates Alpaquita Linux is designed to meet the stringent requirements of a secure software supply chain. It reduces attack surfaces with its minimal and hardened design, offering security advisories and regular updates. With long-term support (LTS) releases and SLAs, Alpaquita provides a reliable and secure foundation for server and cloud deployments. Alpaquita is distributed under EULA (End-user license agreement) — we verified all the packages regarding clean licenses and substituted some software to eliminate the risk of license violation. Alpaquita Stream is continually updated with fresh packages, features, and fixes. It can be used by developers who want the latest software, but is not recommended for enterprise applications requiring stability. Alpaquita LTS is aligned with Linux Kernel LTS. It is a stable production-grade version with a focus on security patches and critical fixes without significant package changes. Alpaquita uses APK as a package manager. Use apk update to update the index of available packages and apk upgrade to upgrade the currently installed packages. Docker images, ISO, and WSL are also regularly updated and available from the corresponding locations. Alpaquita Stream is free to use. In addition, we offer enterprise-grade support for Alpaquita Cloud Native Platform.

We provide updates for Alpaquita LTS for min. four years with two-year overlap between the latest versions. No. Alpaquita is tailored specifically for Cloud/Server deployments with low resource consumption and high performance in mind. To keep it lightweight, we refrained from the GUI functionality. Alpaquita Linux supports both x86 and AArch64 hardware architectures, providing flexibility and compatibility for a wide range of systems. Alpaquita comes with Docker and QEMU support. There are several ways of obtaining Alpaquita binary: directly from our website, Linux repositories, or Docker Hub Container Image Library. Alpaquita Linux supports various languages for application development — Java, Python, C/C++. It is also compatible with Liberica NIK, a GraalVM-based utility for native image generation. Alpaquita containers A lightweight Linux distribution contributes to significant container size reduction. Such distribution contains only the libraries your application needs plus optional packages you can remove or add as required. Alpaquita base includes only the base Linux image Liberica Runtime Container comprises of Alpaquita and Liberica Lite JDK or JRE; Liberica Native Image Kit Container is made up of GraalVM-based Liberica NIK and Alpaquita We also provide Alpaquita images for Python and C/C++ You can add, list, remove, or update packages with the APK Package Manager tool that comes pre-installed on all Alpaquita versions.
