On July 30, 2013, it was announced that Arrow co-creators Greg Berlanti and Andrew Kreisberg, Arrow pilot director David Nutter, and DC Comics CCO Geoff Johns would develop a television series based on the Flash for The CW, and it would detail Barry Allen's origin. Kreisberg revealed after the announcement that Allen would first appear as a recurring character on Arrow in three episodes of season two—all written by Berlanti, Kreisberg and Johns—and the last of the episodes would act as a backdoor pilot for the new show. Kreisberg added that Allen would be a forensic scientist and the introduction of his superpowers, as well as the reactions to this, will be very human and grounded. Johns stated that the character of the Flash in the show would resemble his comic book counterpart, complete with his trademark red costume, and not be a poor imitation. Kreisberg elaborated: "No sweat suits or strange code names; he will be The Flash." While researching the best way to depict the Flash's lightning speed, Johns stated it would not just be the standard "blurring around".

Barry ultimately appeared twice in Arrow's second season, with the planned backdoor pilot cancelled in favor of a traditional pilot by The CW executives, who had been impressed by early cuts of Barry's first two episodes on Arrow. This allowed the creative team to flesh out Barry's story and his world on a bigger budget, as opposed to a backdoor pilot's constraint of incorporating characters from the parent show. The pilot was officially ordered on January 29, 2014, and was written by Berlanti, Kreisberg, and Johns, and directed by Nutter. On May 8, 2014, The Flash was officially picked up as a series, with an initial order of 13 episodes. Three more scripts were ordered in September 2014 following a positive response to newly completed episodes by executives, while a back ten was ordered the next month for a full 23-episode season.

With the commencement of production on the series' second season, former Arrow and Ugly Betty writer Gabrielle Stanton was promoted to executive producer and showrunner; after having served as consulting producer and writer on the first season's finale "Fast Enough". However, it was later reported that Kreisberg would be returning to sole showrunner duties at an unspecified time. That time was later proved to be at the start of 2016, "Potential Energy", when Stanton was no longer credited as being involved with the show. In May 2017, it was reported that Aaron Helbing would be departing the series. Helbing had served as a writer since the first season, and as co-showrunner, along with his brother Todd and Kreisberg, since the second.


Production on the pilot began in March 2014, with filming taking place in Vancouver, British Columbia; additional filming for the series takes place in Portland, Oregon. On how action sequences are shot for the series, compared to Arrow, Gustin said, "When [Arrow] shoot[s] action sequences, pretty much what you see is what you get and they're really doing everything. We do a lot of plate shots that are empty shots of the area we're going to be in and then they're putting us in later in post. I do a lot of the fighting. I don't have to do it full speed and then they ramp it up and a lot of people have to freeze and I keep moving. Then I have to clear frame and step back into frame. It's really tedious stuff that we have to do. On theirs, they learn fight choreography and they shoot it from the perfect angles and what you see is what you get." Production on the third season began in early July 2016.
