Supergirl has 0 post-credit scenes. It also does not have a mid-credits scene, so there’s nothing extra after the movie ends.

What that means

You can leave when the credits start without missing any bonus footage. Several recent reports say the film ends cleanly, with the story’s setup handled before the credits roll rather than in a teaser scene.

Quick note

Some pre-release chatter suggested there might be a post-credits moment, but the final cut does not include one.
