Friday Night Funkin is a rhythm game in which the player controls a character called Boyfriend, who must defeat a series of opponents to continue dating his significant other, Girlfriend. The player must beat multiple levels, referred to as "Weeks" in-game, containing three songs each. Each week, the player faces a different opponent. During gameplay, the opponent will sing a pattern of notes represented as arrows, which the player must then mirror by using their set keybinds; by default the arrow keys (Down, Left, Right), and optionally, and keys. This is done for the duration of the song while avoiding running out of health. • Illustration — Gameplay of the fifth Week For each week, the player has the option to select one of three difficulties: Easy, Normal, or Hard. As the difficulty increases, the speed of incoming arrows increases, and the patterns of arrows become more complex. The player's high score for each week on each difficulty is tracked and shown in the top corner of the week selection screen. Friday Night Funkin contains two different modes of play: a story campaign in which songs are played linearly, and a "freeplay" mode which allows for free selection of any of the music tracks. Selected songs also have harder remixes under the "Erect" and "Nightmare" difficulties.

On October 3, 2020, video game programmer Cameron "ninjamuffin99" Taylor joined the Ludum Dare 47 game jam. Although the game jam's theme was "stuck in a loop", Taylor wanted to create a rhythm game inspired by multiple PlayStation titles, most notably PaRappa the Rapper and Gitaroo Man. Taylor contacted musician Isaac "Kawai Sprite" Garcia for a soundtrack and, after reaching out to various artists, was able to recruit pseudonymous artist evilsk8r and animator David "PhantomArcade" Brown for the project as well. Brown created the game's story—which was loosely inspired by former dating experiences—and collaborated with evilsk8r on the game's artwork and character design, while handling all the animations. Garcia based the game's songs on PaRappa the Rapper, while the characters' voices drew inspiration from Vib-Ribbon. The team released the first version of Friday Night Funkin on October 5, 2020. This version would become known as Friday Night Funkin' (Ludum Dare Prototype). Although this initial prototype did not perform well at the game jam, Taylor and the rest of the crew had plans to continue expanding the game. They reworked and improved the game with more songs and menus, and the first version of the demo was released on both Newgrounds and itch.io on November 1, 2020. The Week 7 level was released as a timed exclusive on Newgrounds. Due to the increase in traffic on Newgrounds, the site crashed. Following the release of Week 7, the developers shifted focus to the full game, titled Friday Night Funkin': The Full Ass Game. The game's soundtrack has been made available on Bandcamp and Spotify. After the release of Week 7, there would be a 3-year hiatus of updates until April 30, 2024, when new updates would again be released semi-consistently, including a new Story Mode level, multiple remixes of previous songs, a mobile release for both iOS and Android devices, and a level collaboration with K-pop group Le Sserafim and their single "Spaghetti".

In April 2021, the developers announced plans to launch a Kickstarter project later in the month to turn the demo into a full game. On April 18, a Kickstarter project for the full version of Friday Night Funkin was released, and reached its goal of $60,000 within hours. The Kickstarter ultimately raised over $2 million. In February 2022, IGN reported that Friday Night Funkin': The Full Ass Game was one of the most funded Kickstarter projects of 2021. The full game was projected to feature a mobile port, more challenging remixes of the standard soundtrack, online multiplayer functionality, and several additional levels. Some of these plans have been introduced in the current demo of the game.

A Friday Night Funkin-themed DLC was added to the rhythm video game Rift of the NecroDancer on December 10, 2025.
