AB Download Manager is a free, open-source desktop application that helps you manage and speed up file downloads. It runs on Windows, Linux, and macOS (and Android), and is built using Kotlin with Compose Multiplatform, a modern UI framework that lets a single codebase produce apps for multiple platforms. Key features include faster download speeds (achieved by splitting files into parts and downloading them in parallel), download queues and scheduling (so you can control when downloads run), and multiple color themes including dark, light, and black modes with a modern interface. Browser extensions for both Chrome and Firefox are available separately, allowing the app to automatically intercept and take over downloads you start in your browser. Installation is straightforward on all platforms: Windows users can install via Winget or Scoop, macOS and Linux users via Homebrew, Linux also has a one-line install script, and pre-built releases are available from GitHub. To build from source, you need JBR (JetBrains Runtime, a specialized Java runtime from JetBrains) and run a single Gradle command. Translations are managed through Crowdin, and the community communicates primarily through a Telegram group. The project is described as early in its development journey, with more features planned.
