From the developer:
Codye helps you present your code in more than 180 languages and more than 100 themes. You can export your highlighted code snippets to PNG, JPEG, HTML, and RTF, while fine-tuning many options to your liking. Codye allows navigating and using most of its features entirely from your keyboard.
You may want to check out more Mac applications, such as RAGE Sitemap Automator, Navicat Lite or WebCrusher, which might be similar to Codye.
