Daring Fireball. Since 2002, Gruber has written and  produced Daring Fireball, a technology-focused blog. He has described his Daring Fireball writing as a "Mac column in the form of a weblog." It was partly inspired by kottke.org by Jason Kottke. The site is written in the form of a tumblelog called "The Linked List", a linklog with brief commentary, in between occasional longform articles that discuss Apple products and issues in related consumer technology. Gruber often writes about user interfaces, software development, Mac applications, and Apple's media coverage. In 2004, Gruber began selling memberships, where readers donate an amount of money annually and gain access to  other perks. The perks included more detailed feeds, but Gruber has downplayed the importance of the extra features, comparing them to "PBS tote bags."

For most of the time when Daring Fireball was a part-time project, Gruber worked as an independent web designer; between late 2005 and April 2006, Gruber's worked at Joyent where he helped with the TextDrive acquisition. In April 2006, Daring Fireball became Gruber's full-time job, funded by advertisement revenue, membership fees, T-shirt sales, and donations from software projects also  hosted on the site, such as Markdown. From 2006 to 2017, the site displayed advertisements from The Deck, an advertising network serving sites like A List Apart and 37signals in addition to Daring Fireball.
