DJ Booth commented on the song, "Faygo sings every line of 'Knock Knock' with the confidence and clarity of a pop star, but, like so many of the scene's creations, his vocals feel stitched together, rough around the edges. The beat, too, has that handmade quality—a see-sawing MIDI orchestra courtesy of Lil Tecca, an underrated producer whose credits run rampant through Faygo's corner of online rap."^[1] Natalie Maher of Elle included the song in her list "The Best Songs on Tiktok to Listen to in Full".^[10]
