How many addons garrys mod can support?
As many as you can squeeze in until you hit the Lua limit (8096 .lua files according to Robotboy655) or your PC can’t handle more. It’s either one or the other.
It crashes with too many LUA addons for me. (Sometimes I have to uninstall some old LUA files.) So it does have a limit.
You won’t crash just for having too many addons. If you hit the Lua limit shit just gets funky from what I recall, it’s like being in “that” part of YouTube. Your reason for crashing probably has to do with some unoptimized addon(s) not working together. Or your CPU is so overloaded it shits itself, that could crash Gmod as well.
That’s caused by the “as much as your PC can handle” part of the Svenskunganka’s message.
