Free and open source apps for Mac and iOS

Ranchero Software

Ranchero Software is a group of volunteers, led by Brent Simmons, that makes great free and open source apps for Mac and iOS.

It is not a company or even a formal organization. It’s just people working together, and everyone is welcomed — and encouraged! — to help out. You can find our repositories on GitHub.

We’re an enthusiastic team of people from around the world. And we think it’s the hottest team in the Mac and iOS worlds. 🐥

Database, scripting system, and development environment for Mac with easy ties to the web. Inspired by UserLand Frontier.

We believe that the features of popular, lovable apps are:

  • Stability
  • Lack of bugs
  • Performance
  • Accessibility
  • Platform-specific design

High quality apps — apps that don’t annoy you with crashes and bugs, that feel light and fast, that fit in with the platform — are the apps that people love and rely on. And tell their friends about.

Though we do add features to our apps, we do it slowly and carefully — because the features listed above are more important than any feature we could add.

While the rest of the industry is moving fast and paying little attention to quality, we’re moving slowly and paying all of our attention to quality.

And we’re setting out to prove that this is the path to success — and that, now more than ever, it’s also the right thing to do.

Yes. We’re on a mission.


If you’ve been around a while, you may recall that Ranchero Software used to be a company. It was founded and run by Brent and Sheila Simmons, and it shipped NetNewsWire 1.0 and 2.0 and MarsEdit 1.0. (And some small apps: Big Cat, TigerLaunch, and Huevos.)

A few years ago we decided to write apps for love instead of for money. 😻 So we closed the company and started writing free and open source apps.
