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).

	Pros & Cons from Real Users Pros Replit is really compelling from a product manager’s perspective because it makes prototyping feel dramatically faster. I can describe an idea, explore a flow, test assumptions, and get something working without waiting for a full engineering cycle. I like that it is not just a mockup tool. Replit helps move from concept to actual software, which is huge for PMs who need to validate workflows, build internal tools, test MVPs, or show stakeholders something more concrete than a slide. The AI agent workflow is especially useful for early product discovery. It can help turn messy product thinking into a plan, build a first version, fix issues, and iterate quickly. That makes it easier to learn what is worth building before committing serious resources. The editor is nice, though it still doesn't compare to local. The deployments feature is also great and easy to use. Repl.it is web based. You can see what your web page looks like at the click of a button. Many other languages (Python, C++, etc.) simple UI. Dark or light mode. Very easy Github integration. Cons I would not treat Replit as a replacement for engineers, designers, or proper product judgment. AI-generated apps still need review, testing, security checks, usability work, and clear requirements. I don't like what this company has turned into. It's buggy, slow, and expensive. Not as much features as paid services, but you can have a $5/month fee for more features (unlimited data, better service, etc). No service that I found (I didn't need it tho).
