batteries included

No assembly required

Batteries included describes products or software that come ready to use without additional purchases or setup.

The phrase originated from toy packaging warnings but now applies especially to programming languages or frameworks that ship with comprehensive built-in functionality: Python is known for its batteries-included philosophy.

The opposite approach requires assembling components yourself.
