Apps and Platforms
Wikipedia explains it in detail, but here’s a shorter answer:
A “terminal” refers to a common, pre-1980s computer interface. For input, a terminal relied solely on a typewriter-like keyboard (the mouse hadn’t really caught on yet). For output, a tiny, monochrome screen only capable of displaying text. The rest of the computer was often so big that it was stored in a separate room.
Modern computers present us with a pleasant façade of buttons and touchscreens, but that old text interface still lives on underneath. Despite the steep learning curve, typing in a terminal can be faster and more expressive than clicking with a mouse.
VT220 –the same as Terminal.app, iTerm, xterm, rxvt, etc.
Cathode supports Unicode and saves files with UTF-8 encoding.
The app can display all Western European symbols, including Cyrillic, Greek, Armenian, Hebrew, and Mathematics.
It cannot currently display Chinese, Japanese, Korean, or Arabic. We’re working on this.
Any Pro Macs or iMacs made since 2007 will perform very well.
For MacBooks, MacBook Airs, and Mac minis, the cutoff is mid-2008.
Please note the following older graphics cards are not supported:
- Intel GMA 950
- Intel GMA X3100
- ATI Radeon X1600
When many effects are turned on, Cathode can take up more CPU and battery than you might like.
There are many ways to control performance:
- Set the rendering quality (minimal, low, medium, or high).
- Lower the frame rate.
- Turn off some monitor effects.
- Disable retina support.
- Increase the font zoom.
- Make windows smaller.
Cathode was inspired by computer screens as they appear in films like 2010, War Games, and Alien.
Tabs (or something functionally similar) are on the to-do list, but they’re not a top priority. We’re exploring some non-traditional ways to share multiple views in a single window.

Yes, with a credit card or a PayPal account. Here’s the link.
The two versions are almost identical. Here are some points to consider:
- Independent customers get app updates immediately, while App Store customers usually have to wait a month or so.
- The App Store version is subject to Apple’s sandboxing policies, while the independent version is not.
- Purchasing and licensing is simple for both versions, but it’s simpler on the App Store.
- When you buy through Apple, 70% of the profit goes to the developer, compared with 95% for independent purchases.
After purchasing you will automatically be emailed a unique license file. Drag and drop this file on top of Cathode.app and you’re done. The license is stored at /Users/username/Library/Application Support/Cathode.
Sorry. Once in a while a license email doesn’t reach its destination.
First, check your spam folder. If you don’t find anything, please email us and we’ll respond with your license ASAP.
One day, but not yet.
- Cathode and Blinky both share the same style, but they’re intended for different audiences.
- Blinky is a simple writing app.
- Cathode includes all the features of Blinky, but it also has full shell access.
- If you’re just looking to have fun and write, try Blinky.
- If you’re a geek who wants to go down the rabbit hole, try Cathode.
