About

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).

About

Spacesuit is a productivity and personal thinking tool designed as a “futuristic canvas” where users can organize ideas freely without the constraints of traditional folders or hierarchical systems. It provides a flexible grid-based workspace where anything can be placed anywhere, allowing thoughts, notes, and resources to evolve naturally as users think and create. Instead of rigid structures, it uses resizable “cards” as containers for ideas, which can be moved, resized, and connected across multiple grids to reflect different contexts or workflows. It includes powerful navigation features like a global search bar and grid linking, enabling users to jump between related ideas and access information instantly. Spacesuit integrates AI processors that connect with models from providers such as OpenAI, Anthropic, Google, and others, allowing users to generate insights and dynamic content tailored to their context.
