Nova
Panic
If we're being honest, Mac apps are a bit of a lost art. There are great reasons to make cross-platform apps — to start, they're cross-platform — but it's just not who we are. Founded as a Mac software company in 1997, our joy at Panic comes from building things that feel truly, well, Mac-like. Long ago, we created Coda, an all-in-one Mac web editor that broke new ground. But when we started work on Nova, we looked at where the web was today, and where we needed to be. It was time for a fresh start. It all starts with our first-class text-editor. It's new, hyper-fast, and flexible, with all the features you want: smart autocomplete, multiple cursors, a Minimap, editor overscroll, tag pairs and brackets, and way, way more. For the curious, Nova has built-in support for 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. -

PromptIDE
xAI
The xAI PromptIDE is an integrated development environment for prompt engineering and interpretability research. It accelerates prompt engineering through an SDK that allows implementing complex prompting techniques and rich analytics that visualize the network's outputs. We use it heavily in our continuous development of Grok. We developed the PromptIDE to give transparent access to Grok-1, the model that powers Grok, to engineers and researchers in the community. The IDE is designed to empower users and help them explore the capabilities of our large language models (LLMs) at pace. At the heart of the IDE is a Python code editor that - combined with a new SDK - allows implementing complex prompting techniques. While executing prompts in the IDE, users see helpful analytics such as the precise tokenization, sampling probabilities, alternative tokens, and aggregated attention masks. The IDE also offers quality of life features. It automatically saves all prompts.Starting Price: Free -

nano
nano
GNU nano was designed to be a free replacement for the Pico text editor, part of the Pine email suite from The University of Washington. It aimed to "emulate Pico as closely as is reasonable and then include extra functionality". The Debian GNU/Linux distribution, known for its strict standards in distributing truly "free" software (i.e. software with no restrictions on redistribution), would not include a binary package for Pine or Pico. Many people had a serious dilemma: they loved these programs, but the versions available at the time were not truly free software in the GNU sense of the word. GNU nano is a small and friendly text editor. Besides basic text editing, nano offers features like undo/redo, syntax coloring, interactive search-and-replace, auto-indentation, line numbers, word completion, file locking, backup files, and internationalization support. Starting with version 4.0, nano no longer hard-wraps an overlong line by default. -

JSFiddle
JSFiddle
JSFiddle has the notion of panels (or tabs if you switch into the tabbed layout), there are 4 panels, 3 where you can enter code, and 1 to see the result: HTML - structure code, no need to add body doctype head, that's added automatically, CSS - styles. You can switch pre-pocessor to SCSS, JavaScript - behavior. There are many frameworks and code pre-processors you can use. Once you enter code, just hit "Run" in the top actions bar, and the fourth panel with results will appear. SFiddle allows you to switch the layout of the editor from the classic 2x2 grid to something that suits your needs. In addition to the grids mode it also has a tabbed mode. Grids are fully resizable. As an addition resizing the Results panel will tell you its width (handy for working on media queries). -
