The series was first announced on November 30, 2018, by the author herself, Wendelin van Draanen, on her official Facebook page, as well as her role as developer for the series. She agreed for it to be shopped to The CC (Cartoon Comedy) as it would mean a chance for developing the story "wondrously" without any "restrictions", such as the books' adult innuendos and references to alcohol. A complete season of 22 episodes, 5 4-parters (each lasting 22 minutes) and 2 hour-long episodes, were ordered to air sometime in late 2019. Voice cast and filming schedule for the series were left out of the announcement and were therefore unknown. The release date was officially announced as August 16, 2019. The series was renewed for a second season of 22 episodes in the wake of the various TV show renewals and cancellations for the 2018-19 TV season by television networks. It is rated TV-14 due to some drug/alcohol use or references and inappropriate language.


On December 31, 2018, after the series finale broadcast of RoboCop titled "Scarlett Night", a commercial aired that featured child actresses Emma Rayne Lyle and Zoe Colletti discussing the Sammy Keyes book series with author Wendelin van Draanen. The last shot of the commercial listed the actresses as the voice roles of Sammy Keyes and Heather Acosta, respectively, along with the remaining cast. The voice cast for the secondary characters would be announced on April 29, 2019.
