In their own words
Castle Game Engine
Castle Game Engine is a free, open-source engine for building 2D and 3D games with a visual editor and an Object Pascal API. The editor supports designing game worlds and interfaces, then building projects for multiple platforms. Listed targets include Windows, Linux, macOS, Android, and iOS, with mobile export, console export, and multiplayer tools. Graphics capabilities include shader effects, physically based rendering, shadows, mirrors, bump mapping, and post-processing. Supported formats include glTF, X3D, sprite sheets, and Spine 2D animations. The project lists Visual Studio Code, Lazarus, Delphi, Blender, and Sketchfab among supported tools and services. A command-line build tool, Docker image, and CI setup documentation support automation. The engine can be used for proprietary applications. Provided Linux binaries require GLIBC 2.34 or newer; older systems can compile from source. Supported operating systems must still receive vendor security support, with Windows 10 temporarily supported as of 2026.
Unity Version Control
Unity Version Control is an engine-agnostic source control tool for game development teams working with large files and binaries. It supports centralized and distributed workflows with branching and merging, as well as file-based workflows for artists. Smart Locks check that a user has the latest version before allowing a file lock, helping reduce merge conflicts. Teams can use Unity-hosted cloud servers or run the server on their own infrastructure. Desktop clients are available for Windows, macOS on Apple Silicon or Intel, and Linux. Named integrations and supported tools include JIRA, Rider, TeamCity, Jenkins, Bamboo, Unreal Engine and Discord. The free tier is free and includes unlimited cloud seats, 25 GB storage per organization per month and 100 GB egress per month; usage beyond included limits is pay-as-you-go. Unity lists on-prem seats at $38 a month. Upload and download communications use SSL, and permissions can be set for repositories, branches and individual items.
