Lua 5.4 generational GC and integer types, LuaJIT still untouchable in performance, Roblox Luau gradual typing and native codegen, the LazyVim and AstroNvim and NvChad and LunarVim explosion in Neovim configs, OpenResty NGINX embedding, Tarantool in-memory DB, Defold and Solar2D and Love2D indie game engines, MoonScript and Yuescript and Teal and Pluto and Fennel variants, and Hammerspoon and Wireshark and Adobe Lightroom embedded Lua — this is a one-shot tour of the 2026 Lua and Luau ecosystem.

Lua 5.4의 통합 GC와 정수 타입, LuaJIT의 여전히 압도적인 성능, Roblox Luau의 점진적 타이핑과 native code generation, LazyVim·AstroNvim·NvChad·LunarVim이 만든 Neovim 설정의 폭발, OpenResty의 NGINX 임베디드 성능, Tarantool 인메모리 DB, Defold·Solar2D·Love2D 인디 게임 엔진, MoonScript·Yuescript·Teal·Pluto·Fennel 변형 언어, Hammerspoon·Wireshark·Adobe Lightroom의 임베디드 Lua까지 — 2026년 Lua/Luau 생태계를 한 번에 정리한다.
