Developing and designing just got easier. The most powerful browser for web developers. Available on all platforms.
Polypane shows your site in multiple viewports at once and keeps them all in sync while you work.
Develop responsive websites and apps twice as fast and get better results, because you wont be skipping screen sizes and wishing for the best.
Build higher quality websites, whether you use Wordpress, React, Angular, Svelte, Bootstrap, Drupal or any other CMS, library or framework.
Polypane has the right tools built-in for developing, debugging and testing, like devtools extensions, live reloading, accessibility testing and more.
Polypane CodeMirrorPolypane is particularly recommended for web developers, front-end developers, UX/UI designers, and accessibility specialists who require an integrated environment for testing different screen sizes, resolutions, and accessibility features in a cohesive manner.
CodeMirror might be a bit more popular than Polypane. We know about 51 links to it since March 2021 and only 40 links to Polypane. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
The point isn't showing what they look like, it's that the result is randomized. Screenshots aren't, so that kind of defeats the purpose. The article starts with instructions on how to actually see and interact with the demos (the easiest is to use [Polypane](https://polypane.app)), as well as a video showing all the demos from the article running in Polypane. - Source: Hacker News / 3 months ago
We also need to talk about Source Order vs. Tab Order—they’re more different than you’d expect 👀. Source Order is the sequence of nxodes inside their parent in the DOM. Tab Order is the sequence of focusable nodes navigated using the Tab key. If a focusable element lacks tabindex, it follows a depth-first traversal of Source Order (visualized conceptually as a traversal path).

That's pretty cool! Get ready to keep these up to date monthly or become obsolete quickly. One of the downsides of tools like this is that your URL needs to be available online so if there's an issue, your iteration loop is quite long. In Polypane [1] I've built social media previews that work with any local URL but also let you overwrite that URL for the social media that display those. I built (and frequently... - Source: Hacker News / about 2 years ago
The address bar in Polypane can match URLs and page titles based on fragments. So you can type po blo 20 to get to e.g. https://polypane.app/blog/polypane-20-browser-features-and-performance/. - Source: dev.to / about 2 years ago
No syntax highlighting in the editor? I vibecoded a more robust browser Filesystem API based markdown editor last week. Recommend either rolling your own with a transparent textbox layered approach or just using Monaco or https://codemirror.net/. - Source: Hacker News / 8 days ago
The query editor in the Trigger.dev dashboard is built on CodeMirror 6 and uses a dual-parser architecture. - Source: dev.to / 6 months ago
CodeMirror – lighter than Monaco, still powerful. - Source: dev.to / 8 months ago
CodeMirror is amazing these days, super lightweight compared to Monaco, and pretty extensible: https://codemirror.net/ For something non-browser, I’m currently using Zed and it’s pretty good: https://zed.dev/. - Source: Hacker News / about 1 year ago
Scrappy co-creator here. Scrappy is local-first, so data is stored locally in your browser, and optionally replicated to a lightweight sync server, to help coordinate syncing between peers. In other words, Scrappy is almost entirely front-end. The only third-party dependencies are Yjs and CodeMirror . We don’t use any other libraries or frameworks like React. There’s no... - Source: Hacker News / about 1 year ago
