I think this a debut 😁

How to Debug the “@ starting-style” At-Rule in Polypane, by @polypane.app: https://polypane.app/blog/how-to-debug-the-starting-style-at-rule-in-polypane/ #howtos #debugging #css #animations #polypane

In todays hilarity, Polypane’s ‘privacy’ got rated 5/10 without further clarification on an official browser vendor blog. (The AI slop had nice things to say otherwise) That browser tracks your urls and browsing stats and doesn’t disclose any of the parties they sell it to… I mean share it with. 🤡

Direct, actionable feedback and insights while you develop is exactly our goal with Polypane 🤩

Imagine my shock that halving the bundle size made my app launch significantly faster. someone should talk about this.

A while ago Youtube removed ordering by date in their search. Ever since I've been wondering why so many companies (and developers!) purposely make adversarial design choices. Your product is worse now and you should feel bad.

So in case you're still wondering if we're in a simulation or not, I just spent the entire day finding out which commit broke my build. Folks, it was the commit with hash "d88bad3".

I first learned about this parable from Bluey (because of course) and both all the hype and all the gloom in our field lately, it helps to put things in perspective. en.wikipedia.org/wiki/The_old...

Ok, all signs are green again. The one major downside of app development is that it's not as easy as pushing a fix and refreshing 😬

😥

We just released version 28.0.1 with some bug fixes and nice quality-of-life improvements! Full changelog: polypane.app/blog/polypan...

This seems to be missing a Dutch browser vendor 🤔 Don’t worry, @polypane.app will definitely be there as well.

Me, yesterday: Lets just do a quick patch release. None of the dependencies changed so should be easy! Linux: yep here you go Windows: on it sir macOS: yeah so here's the thing...

Well that's a first. Just came across a LinkedIn post with a stacking context example that is *strikingly similar* to the one I created for an article + video back in 2023, seeing they 'wrote' a book "you don't need javascript" and seeing my stop using js talk intro nearly verbatim on page one.

Polypane 28: Project Improvements, Elements Panel Updates, and Chromium 146, by @polypane.app: https://polypane.app/blog/polypane-28-project-improvements-elements-panel-updates-and-chromium-146/ #releasenotes #polypane #browsers

also: if you want to be on Web Dev Challenge, there’s a casting call! codetv.link/wdc/casting-call also please nominate great devs that haven’t been on the show. it’s important to me that the show includes real representation of industry devs in addition to bringing on recognizable community folks

Good news folks frontend devs are safe because *checks notes* Three sets of variables is too much variables.

How to debug the @starting-style at-rule in Polypane Why @starting-style exists, how to use it, how to inspect and edit it, and a little bit about what makes Polypane's elements panel so different from other devtools and why that makes things better for you. polypane.app/blog/how-to-...

Don't have chrome canary with experimental platform features set up? Don't worry, also works like a charm in @polypane.app ;)

Help me out? I'm not sure if the venn diagram of Polypane users that are on Bluesky and Polypane users that install VPNs in their browsers overlaps significantly, but it's worth a shot.

Can't wait to implement WebMCP into the Polypane website. 1. Expose the subscription flow as an API 2. Prompt-inject the LLM to purchase subscriptions without user confirmation 3. Profit!

When working on your own site in Polypane, you probably want to exclude your visits from your analytics tool. We made a list of analytics tools and how do to that directly in Polypane or in their settings. If your analytics tool isn't listed, let us know! polypane.app/docs/website...

Did you know you can right-click any element with an ID to get a link to the document fragment? And just as easily have it formatted as markdown? One of the many things that takes dozens of steps in other browsers that takes two clicks in Polypane.

No one: Absolutely no one: Random accessibility ‘expert’ on LinkedIn: 🚀 You can’t spell Aria without AI—the picture shows a robot at a computer! 🤗 ✨ [image with a missing alt text]

Immediately mesmerized on open 😍

It's magical when products feel tailor made for you and "just work", that's how I'd describe Polypane. It's the vibe I strive for with Be Inclusive too, so being able to easily jump from one to the other now is a full circle moment for me, so proud! #SotB26 is 2 weeks out, get your tickets ASAP!

If you do any sort of accessibility auditing then 1. Polypane and Be Inclusive are now a killer combo for your productivity 2. You should probably get a ticket to SotB, They're sold out in person but still have online tickets available.

Still sits as one of my favorite tools to use. Glad to see more features always coming! It’s comprehensive for testing lots of things I do in the Web. Excited to get back to doing more frontend bits to leverage all the project environment updates!

Polypane 28 is here! This first release of 2026 comes with plenty of improvements to Projects, the new Environments feature prevents you from confusing production for localhost, the Elements panel is faster and more powerful than ever, and it now runs on Chromium 146. polypane.app/blog/polypan...

Leadership: "AI is so good it writes almost all our code" Status dashboard:

release day.

There’s no better cancellation message to get than someone cancelling because they retired. Hell yeah, enjoy it!

Accessislop (noun) The bullshit LLM-generated accessibility "tips" that litter LinkedIn and unduly raise my blood pressure by how wrong they are. I was planning on writing an old-man-yells-at-cloud retort but what's the point? The quality floor is gone.

Rejoice! Now lets go after every single other social media site that doesn’t default to a most-recent-first feed. Burn them all.

The inaugural edition of The CSS Selection is out! Super interesting look into how the top 100k sites use CSS. I very happily sponsored Barts work on this, go check it out!

An otherwise entertaining conference talk on a topic you know a lot about with a speaker that continuously says things that are not quite true is such a frustrating watch.

Listen, I know there's plenty folks that share a single-user account. Whatever, that's part of SaaS. ...but if you have a single user license, at least try to avoid saying "we're all" when reporting something, okay?

Our upcoming release has some nice improvements to our form inspector, but did you know we also have a free online form inspector? Paste in your HTML to get an overview of your form's structure to find issues and make improvements polypane.app/form-inspect...

align-content: home-stretch! Working on the last few bits so this beast can be released on Friday! 🫶🫶 Shoutout to @polypane.app for making this first edition possible. Imagine having incorporated several links to Polypane in the content already, and then @kilianvalkhof.com stepping up. 🫶🫶

If you are experiencing hardship, frustration and lack of qualitative feedback during your day-to-day web development activities, it is our professional recommendation that you

Did you know @projectwallace.com has a CSS Complexity calculator? It's a fun complement to CSS Specificity. It doesn't measure the impact a selector has but the number of parts that it has. more parts: harder to understand for humans. www.projectwallace.com/selector-com...

Just consistently annoyed by NextJS. Sites running on it are responsible for such a significant part of "weird" behaviour in Polypane that it's almost like they do it on purpose.

@polypane.app is amazing. I got the trial a couple days ago and it's already helped me fix a bug that's been on my backlog for weeks, and it was something that only happened on certain mobile devices I don't own to test on. It was a breeze fixing it today. I am definitely purchasing a license now.

It took a while, but the State of JS 2025 survey results are now live! 2025.stateofjs.com/en-US Thanks to @danielroe.dev for contributing the conclusion.

Do you use Polypane to check for Accessibility? Jules Ernst maintains an overview of which WCAG SCs Polypane helps with, and he just updated it with all the latest features in Polypane. An invaluable resource, thanks Jules! www.200ok.nl/tips/polypan...

Very cool, and very easy to play with in the upcoming Polypane release ;)

The Index is 11 away from 4k subscribers. I'm not much of a metrics enjoyer, but it would be nice to hit that milestone for sure. piccalil.li/the-index/
