XCX is a statically typed, multi-paradigm backend language built in Rust. HTTP, SQLite, JSON, crypto, and file I/O are part of the language itself - no frameworks, no ORMs, no boilerplate. Write logic; the runtime handles the rest.

|---|---|---|
| XCX 4.0 | ✅ Released | Full architectural rewrite of the VM and JIT, zero-copy JSON, arena allocator, reworked REPL |

XCX runs on Windows, Linux (Ubuntu, Arch/Manjaro, and generally all major distros), and has an experimental FreeBSD build.
XCX is developed by a single contributor. The language is usable for small backend services and tools; production use in large systems is not recommended at this stage.
