Re-Logic

 is an independent game development studio which has developed Terraria as well as an earlier fan-game, Super Mario Bros. X. Re-Logic is also a publisher of the side-scrolling real-time strategy video game  and the turn-based strategy video game Pixel Privateers. The company is located in Indiana, USA.

Redigit
Andrew "Redigit" Spinks is the creator of Terraria and President of Re-Logic. Before Terraria, he was the lead developer of Super Mario Bros. X (SMBX). In early development of the game, Redigit released a play-through of the game, which can be viewed on YouTube to this day. He announced quitting development of Terraria in February 2012, but hinted at a return to the game in January 2013, confirming to start working on an update just two days later. He originally moved on from Terraria during the early stages of the development of 1.3 to start looking into new coding languages for his next project, however he later continued working on Terraria again until the update was finished. As of the 1.3 release in June 2015, he almost entirely focused on Terraria: Otherworld, which has been confirmed cancelled in April 2018, but he once more returned to work on Terraria for the 1.3.5 and 1.4 updates.

Redigit is Cenx's husband.

The name "Redigit" originates from the TV show  where talks about a  gun. Spinks misunderstood this as "redigit".
