It premiered on January 12, 2016 and aired on Tuesdays at 9:00 – 10:00 p.m., ET/PT on Freeform. It was also distributed internationally on Netflix.
Based on the New York Times bestselling young adult fantasy book series The Mortal Instruments by Cassandra Clare, follows 18 year-old Clary Fray, who finds out on her birthday that she is not who she thinks she is, but rather comes from a long line of Shadowhunters — human-angel hybrids who hunt down demons. When her mother Jocelyn is kidnapped, Clary is thrown into the world of demon hunting with mysterious Shadowhunter Jace and her best friend Simon. Now living among faeries, warlocks, vampires and werewolves, Clary begins a journey of self-discovery as she learns more about her past and what her future may hold.

At MIPCOM on October 12, 2014, the development of the project was first revealed by Constantin Film, instead of the initially planned The Mortal Instruments: City of Ashes sequel to the first film that was initially set to begin production in September 2013, before it was delayed and ultimately scrapped.
The plan and vision was to relaunch The Mortal Instruments as a high-end drama series with one-hour episodes and as a complete reboot of the film. Producer Don Carmody expressed his desire to make the show a limited TV series, hoping to release a season (one per book) every year and shooting it in Toronto, and Constantin Film revealing its aims to spend 2.5-5 million per episode. Unique Features' Bob Shaye and Michael Lynne were onboard as executive producers, as they were on the film. Ed Decter was also hired as showrunner, executive producer, and head writer of the first season.
Cassandra Clare first shared the series' working title "Shadowhunters" on Twitter in February 2015. Along with a confirmation and extension of the title, it was revealed by an OLV source that production was set to begin in May that year in Vancouver. A Craigslist LA listing also put up the information of the series pilot, confirming the previous information and revealing casting notices, as well as part of the show's description. Casting sides were also made available online, and some audition videos, along with speculations that came with the script portions, eventually made its way online.
Author Cassandra Clare eventually met with the network that picked the series up. Days later, on March 30, 2015, it was officially announced that the series was given a 13-episode straight-to-series order on ABC Family.
The series is part of a broader strategic shift at Constantin that will see the German-based company move into English-language television series, one of several television adaptations of several of its English-language movie properties, including Perfume: The Story of a Murderer and Resident Evil. The project also marks ABC Family's first scripted "saga-to-series," and comes as the Disney-owned cable network is plotting a rebranding to target older viewers and families alike.
It was soon revealed that production would take place in May 2015 in Toronto. McG's involvement as executive producer was then announced. ABC Family later announced that Shadowhunters is part of its early 2016 programming, premiering alongside another book adaptation project, Recovery Road. Production began in May (principal photography on the 25th) and ran until October 2015. Cassandra Clare has also stated that the show will be quite different from the books and is more like an "interpretation", and that it will not be a book per season. She also revealed that the first season would incorporate elements from later books, which was also supported by the early appearances of characters that appear much later in the book series.
Casting was already a priority during early stages of development, as well as a concern among fans. The first real update was released through the Craigslist LA listing posted on March 4, 2015. Alyson Silverberg, Jonathan Clay Harris, and Anthony J. Kraus serve as casting directors, and Susan Esrock and Justin Kiang as casting associates. The pilot ad included character descriptions of Clary, Jace, and Simon, all revealed to have been aged up a few years from their book counterparts. The presence of casting sides online on sites such as Showfax and SidesExpress was also revealed. There is some indication that Isabelle, Alec, Jocelyn, Valentine, and Luke, as well as Dorothea, were among the other characters being auditioned for at the time. Some audition videos also made their way online. Via Twitter, McG publicized updates regarding the casting process, along with some production notes, in April.
On April 20, 2015, it was announced that Dominic Sherwood was cast as Jace. Casting of the main characters continued in May, with Alberto Rosende, Emeraude Toubia, Katherine McNamara, Matthew Daddario, Isaiah Mustafa, Alan Van Sprang, Harry Shum Jr., and Maxim Roy landing the parts of Simon, Isabelle, Clary, Alec, Luke, Valentine, Magnus, and Jocelyn, respectively. Other recurring roles beyond the pilot were cast and announced after.
On June 4, 2018, it was announced that Shadowhunters was cancelled, in part due to Constantin Film losing its deal with Netflix, and the premiere of the second half of the airing third season was delayed by around six months. An additional two episodes, which aired as a two-hour series finale, was ordered in order to give closure to the storyline.
Due to the unforeseen cancellation of the series and the sudden order for two additional, ending episodes after filming proper for the season had already wrapped, some of the actors had already committed to other projects. This included Alisha Wainwright, who portrays Maia Roberts. Wainwright could only manage to shoot all her scenes for the final episodes in one day. The closing story for Maia was adjusted accordingly; according to the actress, the showrunners shared with her the details of what they would have liked to do with the character if they had more time with her. Isaiah Mustafa was also filming It: Chapter Two and was barely present in the finale episodes.
Less than a month after filming for the finale episodes wrapped, an online auction of the Shadowhunters props was made public on 403 Auction, with its names and descriptions spoiling some events from unaired episodes before they were removed following outrage from the fans and involved crew members.
By that point, the writers already had plans and ideas mapped out for a fourth season. The finale episodes, which were written on short notice, consist of story lines intended for the cancelled season, condensed and hastily wrapped up in two episodes. In addition, the original ending of what was supposed to be the season finale, City of Glass, was also changed, with the cliffhanger removed and instead incorporated into the new episode for better transition into the story's conclusion.
Had the show not been cancelled, the writers hoped to delve into the following story lines:
- Magnus embracing his dark side with Asmodeus, and Alec eventually bringing him back;
- Jonathan's reign of terror, long metamorphosis, and his relationship with the Seelie Queen;
- Simon and Isabelle's romance would have finally been front and center after seasons of building them up. Isabelle's heavenly fire conundrum, and their trip to Edom, would have taken longer.
- Helen Blackthorn and Aline Penhallow's romance would have been explored and highlighted. Helen's siblings, the Blackthorns, at the Los Angeles Institute would have played a big part; specifically, the murder of one of Helen's siblings would have been played out.
- Maia's arc as pack alpha and Luke as a Shadowhunter and his life in the New York Institute;
- The showrunners would also have liked for Magnus and Alec's wedding to have taken longer to plan, and for more interactions to have taken place at the wedding, such as Jace thanking Magnus, Robert being happy that Maryse found love again, and for Luke and Maia to simply have been at the wedding, and more moments that could hypothetically have taken up an episode.
- Clary would have been racked with guilt over her actions when she was with Jonathan and would have been driven to clean up her mess, while Jace would have helped her try to return to normal. Their relationship would have normalized somewhat, with more moments like the date they had in the third season.
- Jace and Clary getting married would also have been a possibility.
- Clary and Isabelle becoming parabatai would have been built up later down the line.
