BYOND
What BYOND is
BYOND is a free, closed-source gaming engine and community for creating, playing, and publishing games, especially multiplayer games. Developers use DM, a language designed to handle multiplayer interaction without requiring them to maintain complex networking infrastructure. BYOND lists free developer tools, built-in multiplayer support, and support for classic 2D or isometric games. Its stated targets are Windows and Linux for development or hosting and modern web browsers; listed platforms are Linux, web, and Windows. Most games can be played as a guest. A free account can save game information, track medals, and provide a password-protected identity. BYOND does not provide mobile export. The native Linux client can host games but does not provide a graphical Linux client; graphical Linux use is described through WINE or a virtual machine. Integrations include a MySQL client connector and built-in SQLite support. The software and developer tools plan costs nothing.
