Does Get Out have a post-credit scene?

There is no scene during the credits and nothing after them. Get Out ends on Rod's TSA cruiser pulling away from the Armitage driveway, and Jordan Peele holds nothing in reserve.

The placement is the point. Peele rebuilt the ending specifically so that the release of tension lands on Rod's arrival — his stated reasoning was that the finale "needed to transform into something that gives us a hero, that gives us an escape," and that "there's nothing more satisfying than seeing the audience go crazy when Rod shows up." A stinger would have re-tightened a knot the film spent 104 minutes earning the right to cut.

He shot the opposite version first. In the filmed alternate ending, the vehicle that arrives is a police car, Chris is arrested at the scene, and the film jumps forward to a prison visiting room where he tells Rod he has made peace with it because he stopped them from hurting anyone else. Peele, on his own commentary: "you're meant to think — oh snap, wait a second, is that a good thing, is that a bad thing?" He shelved it because the world outside the theatre had already made that argument without his help. A second, unfilmed idea had Chris escape the community entirely, then meet Rod later and deny through a window reflection that he had ever known Rose.

All of it lives on the home release alongside the deleted scenes and Peele's feature commentary — which, for anyone hunting this film's hidden details, is the single most valuable extra attached to it, since a large share of Get Out's confirmed easter eggs come straight off that track rather than out of journalism.

Nothing sets up a sequel. Peele has never treated Get Out as the start of anything, and Us and Nope are unconnected originals rather than a shared universe. When Rod tells Chris he warned him not to go in that house, you have seen the whole film.
