To be candid, Mac applications seem to be fading into obscurity. While there are valid motivations for developing cross-platform applications — primarily their versatility — it doesn't align with our core identity. Established as a Mac software developer in 1997, the team at Panic finds joy in creating products that embody the essence of Mac. Many years ago, we introduced Coda, a groundbreaking all-in-one web editor specifically for Mac users. However, as we began developing Nova, we reassessed the current landscape of the web and recognized the need for a new beginning. Hence, our journey commenced with a top-tier text editor that is not only brand new but also incredibly fast and adaptable, packed with all the essential features like intelligent autocomplete, multiple cursors, a Minimap, editor overscroll, and tag pairs and brackets, among many others. For those interested, Nova offers integrated support for a variety of languages including CoffeeScript, CSS, Diff, ERB, Haml, HTML, INI, JavaScript, JSON, JSX, Less, Lua, Markdown, Perl, PHP, Python, Ruby, Sass, SCSS, Smarty, SQL, TSX, TypeScript, XML, and YAML.
