Polypane 29 is here! 🥳
It comes with our take on a network panel, our snippet store, a custom selector outline, the best way to test pseudo states, passkey support on macOS, WhatsApp previews, grid/flex overlay visualizations and, like, 10 more things.

By the way, did you know the browser helper extension also registers a shortcut?
Press alt/opt P on any tab to send it to Polypane. ✅
We updated our browser extension that lets you quickly open URLs and links in Polypane!
A big theme in our survey was about lowering the friction of opening Polypane. Now the extension shows an on-page button for all local pages, making it super easy.

If the button is in the way, you can quickly collapse it, so it's still there when you need it, just not as visible.
If the top right corner doesn't work for you, you can place it in any of the other corners or fully hide it from the extension menu.

Recently discovered tools giving me tons of joy:
- ⌨️ Haptyk (mechanical keyboard sounds)
- 🏝️ Vibe Island (notch/Dynamic Island to manage agents across sessions/terminals by @edwardluox)
- 💻 @polypane (a very cool development browser)
- 📁 Consul (convert files by renaming)

Safe-area-inset lets you make the most use of device screens, even with their pesky notches or islands that get in the way.
Check out our deep dive to learn how to use safe-area-insets, what to use them for, and the best way to test them on desktop.

Polypane. Browser for devs who care retweeted
Polypane has pixel perfect social media previews for ten different social media platforms. That's already much more than any other tool out there.
But Polypane is the kind of app that goes to 11. 🧑🎤
So we're adding WhatsApp in the next release.

We make good use of the Intl API in our app and on our website, so it was high time we did a Polypane-style deep-dive on it.
Check out our new article, play around with the interactive examples or hear Kilian yap about it on video. Whatever works for you!

Want to share a WIP of your localhost?
That's just two clicks in @Polypane. You even get to drive the experience since your interactions are synced.
polypane.app/portal/
Been playing with the cursor cloud agents and I was surprised the terminal wasn’t locked down. I could install anything
Do you guys have any plans to surface the localhost urls to the web automatically so I could share a WIP?

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

If you tried installing a VPN or proxy extension into Polypane, can you tell us why?
It happens a lot and it's a use case we really want to understand. We follow back, so you can DM if you prefer 🙏

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 tool isn't listed, let us know!

Special shout-out to @SimpleAnalytic which automatically filters out Polypane without you having to do anything 🙌

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.
ALT A context menu on a header, showing a list of options like "inspect element" and "reload this pane". The cursor is on a highlighted item named "Copy link to document fragment".

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 than ever, and it now all runs on Chromium 146.
