Sure it's not
SimPE? That's the only programme I know of that lets you do all of that. It's entirely free, and is updated to work with all EP's and SP's up to AL/MG.
You can change things in the neighborhood folder; change the sims' eyes, skintones, ages and so on; recolor furniture; make mods/hacks; make new mesh packages for hair/clothes/accessories... Pretty much everything possible.
Takes some time to learn everything - but there are plenty of tutorials
SimBlender is practically a simplified version of insimenator, and is a bit less likely to cause any harm to the game. But it won't let you change skintones or backup neighborhood files or anything like that.
