A contactor is an electrical switch used for switching current on and off in a circuit without overload protection.

A starter is usually an assembly, that includes a contactor plus an overload relay, used to start an electic motor.

Contactors are rated by their current in amps while starters are rated by their horsepower capacity and the current they use.
