You can see everything was INCREDIBLE.

example.com just changed for the first time since 2013, and IANA replied to my email asking why. Here's the full reply: www.oliverdunk.com/2026/09/30/i...

Sad to be missing the eclipse, but I’m currently on a work trip somewhere where it won’t be visible. Even if it was visible, I don’t want to be accused of moonlighting 🤭

Build a 30-second timer Chrome Extension in record time with Antigravity! Learn a pro-tip for AI prompting and see your extension come to life, then load it in Chrome in a flash ⬇️

@remysharp.com Hey Remy! Could we DM about something I’m working on? Or happy to drop you an email if you’d prefer :)

Don't mind @oliverdunk.com, he's just practicing for #GoogleIO 🗣️ Catch all the latest announcements, including exciting Chrome Web Store and Chrome Extensions updates. Register today → goo.gle/io2026reg-6

I’ve been playing around with using Antigravity to build Chrome Extensions. Here’s a video with a look at how I set things up, including things I add to the agent’s context: youtu.be/i1OCGChwO_I?...

@geofftech.bsky.social Anything planned for the Cutty Sark DLR station re-opening? It’s my local and I’ve been waiting for so long 😅

Are folks mostly interacting with agents in the foreground when coding with LLMs, or has running agents in the background taken over?

We’re keeping you here in spirit!

Curious about how to monetize a Chrome Extension? We just published a video with a lot of really interesting stats on typical conversion rates / best plan structure etc. youtu.be/7i2N7Hqyqyg?...

Can you use React to build a Chrome Extension? What about Angular and Svelte? (Spoiler: Yes, you can!) This video from a couple of weeks ago has the answer, along with some general advice: youtu.be/XfsXCfv7wKM?...

Great time in Bletchley Park looking at enigma machines!

I’m surrounded by upcoming ad-breaks (UK based folk would understand: www.youtube.com/playlist?lis...)

@danabra.mov Hey Dan! I’d like to make some videos on the Chrome for Developers channel about when React makes sense in Chrome Extensions and how to use it best. Would you be interested in being a guest or providing some input?

Sam’s replies are well worth a read!

Curious as a potential video topic - what should developers be looking out for in the AI space in 2026?

2025 was a massive year for Chrome Extensions → goo.gle/4pY10Ey From completing the Manifest V3 transition to launching new built-in AI APIs, @oliverdunk.com breaks down every major update you might have missed.

One last video for 2025! Here’s everything that happened with Chrome Extensions this year: youtu.be/nOfyMlIu4jc

If you’re using server-side AI models, you usually need an API key to call them. A couple of weeks back I made a video looking at how to handle that in a Chrome extension: youtu.be/pl4pz4nWa3w

For the first time, the Web Extensions specification is linked on MDN! As we start building it out, I’m excited to see this more 🙂 developer.mozilla.org/en-US/docs/M...

GDE @henrylim96.bsky.social talks about web performance at #DevFest Birmingham 2025 - @tunetheweb.com would be proud!

It is @oliverdunk.com!🔥 Oliver is talking about how you can build web extension (Side Panel API, Built-in AI) at #DevFest Birmingham 2025. @developer.chrome.com

As part of #PasskeysWeek, I’ve been working with @agektmr.com and the rest of the team on some new videos addressing common misconceptions. Here’s the first one: youtu.be/H2naJinRzDA

Here’s my talk from #DevFestNantes! I’ve given this one before, but I think this is the most polished recording 🙂 youtu.be/IlappZPeMUM

Watching a great talk by @oliverdunk.com just starting some live demos with Built-in AI APIs. The demo gods are behaving so far! 🤞😀💯

Do you think stale issues or those for bugs which are unlikely to be fixed should be closed? Why / why not?

If we started Chrome Dev Summit again, would you be interested in it? (huh - apparently can't do polls here...), Please reply, Yes or No, or any other answer in between.

I see a lot of confusion around if Chrome Extension APIs are cross-browser, and to what extent browsers agree on Manifest V3. What questions would it be most helpful for us to share answers to?

Behind the scenes before my @squiggleconf.com talk 👀

Got questions about building Chrome Extensions? We’re recording some new videos for the @developer.chrome.com channel in October, and I’d love suggestions for topics we should cover: www.reddit.com/r/chrome_ext...

We’re on Bluesky now!

I’ll be speaking at DevFest Nantes! I’m doing a wizard themed talk, so I’m planning to learn a magic trick to perform at the start of my session - wish me luck!

I made a quiz about the JS Date parser is. It's very easy and you will score very high. jsdate.wtf

Can’t wait! I think this is going to be a great event and I would love to see people there 🙂

That’s me! Super excited about this event - I’ve heard great things from friends and colleagues.

Had a great evening at @tldraw.com’s “good content for developers but how” event. Great talks from @todepond.com, @neoeno.bsky.social and @mattpocock.com.

Just read “Everything is Tuberculosis” by John Green - A fascinating perspective on how our biases affect medical treatment in the 21st century.

Had a lovely surprise yesterday: @oliverdunk.com reached out to let me know that my talk at #SvelteLondon about building cross-browser extensions was featured on the Chrome Developer blog 🥳 #Svelte #WXT

I bought some Sonos speakers and I’m quickly becoming the person that complains when something isn’t Dolby Atmos 😂
