It was released through Grand Hustle and Epic Records as the seventh track from the former's debut studio album, Rodeo, on September 4, 2015.
Josephine Cruz of Hypebeast described the song as "one of the strongest tracks" from Rodeo, elaborating: "Backed by standout production and a catchy hook, this a testament to the songwriting chops of all three of these young rappers, and while a lot has been made of Swae Lee's 'influence' on Travi$' style in recent months, here there's room for everyone to shine".
[1] Matthew Ramirez of Spin felt that "Swae Lee's cherubic voice contrasts nicely with Scott's groaned delivery and Chief Keef's Auto-Tuned mumble on 'Nightcrawler,' which hits its precise aim of ominous and fun".
[3] In 2018, over two-and-a-half years after the release of the song and album, Aaron Williams of Uproxx summarized that "Travis' best songs are often marked by star turns by guest stars acting as foils for his artistic proclivities and 'Nightcrawler' is one of the best examples", adding that "while Travis' singing is often the centerpiece of his catchier tracks, Rae Sremmurd's Swae Lee comes through to highlight just how good Travis is by providing a comparison point for his crooning against one of the best in hip-hop (another great example is Swae's 'Close' from his own album earlier this year)" and "Scott's warbling stands up against Swae's, illustrating the polish on his well-rounded artistic versatility".
