What’s the best lightweight LUA executor for scripting in 2025?

[Callum Hanna]

Hi everyone,

I’ve been looking into different scripting executors for testing and automation purposes. Most options I tried either add a lot of overhead or require complicated setups with key systems.

Recently I came across Fluxus Executor v2.690 (@https://fluxusteams.com/) it runs LUA scripts pretty smoothly, supports multiple platforms, and doesn’t need a key to start.

Has anyone else here tested it or something similar? Curious if Fluxus is considered reliable compared to other executors, or if there are better alternatives in 2025.

Fluxus runs fine, but if you want something really lightweight and reliablestick with official Lua 5.4 (tiny, no overhead) or LuaJIT if speed matters. Fluxus is more of a convenience tool, while Lua/LuaJIT are the “set and forget” options.

Thanks for clarifying that! Lua 5.4 and LuaJIT are definitely solid choices when speed and low overhead are priorities.
