VK's KittenPHP/DB/Engine suite: a PHP-to-C++ translating compiler (KPHP) plus a set of specialized high-performance non-relational database engines developed at VKontakte since 2009. It is battle-tested in VK's high-load production environment and released under GPL-2.0/LGPL.

Use cases

• compile PHP code to fast native C++ binaries
• run high-throughput backend services for social networks
• deploy specialized key-value and non-relational storage engines
• speed up a large legacy PHP codebase
• study production-grade PHP compiler and storage engine internals

When to choose

• you operate very high-load PHP services and want native-speed execution
• you need VK-proven specialized storage engines
• you want to learn from a real-world PHP-to-C++ compiler

When to avoid

• you need modern KPHP development - it moved to the separate vkcom/kphp repository
• you need English documentation - only Russian docs are provided
• you want a general-purpose relational database or a typical PHP framework
• you need active community support or recent releases
