releaser

One who frees

A releaser is a person or thing that releases—sets free, lets go, or makes available.

In biology, a releaser is a stimulus that triggers an instinctive behavioral response: The red spot on a gull's beak acts as a releaser for chick feeding behavior.

The term appears in technical contexts more than everyday speech.
