KotlinConf 2026 CFP is open! 🔥 Looking forward to all your awesome submissions, and hearing about all the cool things everyone has been up to😁 sessionize.com/kotlinconf-2...

Watching at @sebi.io and @zsmb.co talking about building with AI in Kotlin!

Koog, the Agentic AI framework for Kotlin that we're building at JetBrains, is, well, kind of cool. Especially since it's not designed for toy projects, but to ✨ scale ✨! Learn more: medium.com/@vadim.brili...

@lilywhiteout.bsky.social Azerbaijan Kodee greets you!

If you have feedback about *anything* around Kotlin, this is the time to have your voice heard in our annual Kotlin Developer Survey. The language, the tooling, the ecosystem, Kotlin Multiplatform, Compose... It's all in there! Takes just 10 minutes:

We're running the Kotlin Developer Survey 2025; make your voice heard! 🎤 Help us understand what's great when working with Kotlin, and what's not! You'll help make Kotlin better not just for yourself, but for everybody! Thanks in advance ❤️ surveys.jetbrains.com/s3/68aaa1b46...

🎉 New Talking Kotlin episode! @sebi.io chats with Alex Sysoev, author of KotlinX RPC, an experimental but powerful library for building RPC services and clients in Kotlin. Watch on YouTube 👉 kotl.in/572emq

@sebi.io as he's looking at our YouTube channel (Subscribe here! www.youtube.com/@Kotlin)

A nice conference about #ComposeMultiplatform for iOs and more by @sebi.io at #KotlinConf 25 www.youtube.com/watch?v=YKTl...

OH FUN FACT FOR THOSE WHO DONT LOOK AT MY X/TWITTER i drew fanart for this

Kotlin coroutines are great. Their core primitive is the suspending function. With a small change in your IDE settings, you can give them a custom color (like a bright green), which makes it easy to spot them at a glance, even when you're looking at a lot of code.

the brain that can see a face in a wall outlet was always doomed to hear the voice of God in a markov chain

something something @nanami.codes something something this looks so ass IM SORRY

@nanami.codes found you a date

And as a reminder, you can already run the same code on iOS, web (hah) and desktop already. You even get Compose Hot Reload for live tweaking in that last case!

If you’re a Kotlin library maintainer, consider submitting to the Kotlin Foundation Grants program for a chance to get financial and promotional support for your library! 🚀 Deadline is July 31, don’t miss it!

Somehow I missed the livestream with @sebi.io and the Kotlin language designers! I don't know how it happened 🤯 Did you miss it too? Quick, let's watch it before they notice! www.youtube.com/watch?v=jne3...

Video of my talk at @kotlinconf.com 2025 now publicly available youtu.be/O0BqoLcRuJI?...

In two days Mikhail Zarechenskii, @sebi.io and I will be exploring the new features of @kotlinlang.org 2.2 in a livestream. Learn about the new tricks, and ask any questions you may have! 📅 July 10 ⏰ 4:00 pm CET 👉 kotl.in/2-2-livestream

At KotlinConf 2025 I gave a 15m talk stuffed with all the information I could about Structured Concurrency and Coroutines in Ktor! 🗣️ KOTLIN SERVER SIDE PEEPS! Perfect for a small break in this heat 🥵 Grab a drink & stay hydrated during these warm days! www.youtube.com/watch?v=JxTI...

New favourite piccie from the past week at @droidcon.bsky.social New York with the absolute legend that is @sebi.io ! If he still has the AI altered version of this it's absolutely hilarious & will likely be his new Greatest Hits Album cover ;) ;) #dcnyc25

“Compose Multiplatform for iOS: Ready for Production Use” 🚀 In this KotlinConf’25 talk, @sebi.io shares what’s new, what’s under the hood, and what’s next. 📺 Now available on Kotlin YouTube: kotl.in/conf-compose...

Was watching @sebi.io's fantastic video on using Kotlin MCP SDK to control Hue lights (www.youtube.com/watch?v=jwev...) and he mentioned you could also run IntelliJ as MCP server....so used prompt here to build project (using Android Studio in my case) and set office lights to green if successful 😀

It's "bring your husband to work" day!

i love kotlin

Really impressive demo by @sebi.io using Junie AI with Compose Hot Reload #KotlinConf

We have new AI Assistant and Junie licenses and pricing, including FREE access! Check it out below:

Great session today (@zsmb.co was also hosting). Testament to maturity of KMP that related question are getting more detailed each year. Lot of CMP questions this year as well.

I love using JetBrains Junie for creating applications that does something I don't know how to do, or for things that are better explained by example than explanations

🙂

Yes, hot reload really is 🔥 #Kotlin #KMP #CMP youtube.com/shorts/xgtHm...

@jetbrains.com has joined the chat. Tried Junie's EAP version with my github.com/iurysza/modu... project. IMO the sweet spot for these kind of tools are projects with a clear (and narrow) scope. Worked super well so far. I liked how it was smart enough to figure out how to run tests by itself.

Enjoyed presenting at Appdevcon in Amsterdam on Kotlin Swift Export.

Compile time DI verification with #koin in #kotlin! The Koin project has grown incredibly over the years. Impressive work 👏👏 Always amazing to see #OSS projects grow with the community, and language. It’s really marvellous to see what motivated people can accomplish working together. 🥰

Junie is such a huge help for quickly getting an implementation of e.g. an API client. For a video, I was implementing smart light control with MCP, and I was able to delegate the REST client entirely to our agent. Fewer mechanical tasks, more focus on the things that matter 🚀 youtu.be/jwevCa96Z4Q

www.youtube.com/watch?v=jwev... Kotlin 🤝 MCP @sebi.io nailed it on this one! I rly want to try this out! github.com/SebastianAig...

🔥🔥 Hot Reload for Compose Multiplatform is a game changer for iterating on your UIs – it allows you to instantly see and “feel” the changes you make as you tweak your app! Give it a try! 🧵👇

god bless Junie 🙏 "make a program that reads an xml, takes the values found Field1 and encloses them in single quotes and comma separates all these values then saves them to a file, chunked to 800" Junie: "okiedokie :)" me: update Table1 set column1=foo where ID in (juniedata) i could cry

nothing hotter than attention to detail

There’s nothing I love more than going through an entire login flow in a web app only for it to realize at the very last stage that it wanted to deep link into the app instead. You know, the app that’s already authenticated. Great stuff.

@daveceddia.com thank you again for building Recut -- you've saved me 741 manual cuts today ❤️

🎉 The Amper project now has a public `main` branch on GitHub, so you can take a sneak peek at the latest developments before they make it into a release! Check it out ⤵️ github.com/JetBrains/am...

A glimpse to the Android Studio history by @yo-le.bsky.social yole.blog/2025/01/27/m...

Lots of you were asking for AI Assistant in Android Studio, it's finally ready to try!

Inspired by this article, I built a small tool in Compose Desktop to more easily iterate through building fancy mesh gradients from @sinasamaki.com's Modifier recipe! Code is here github.com/c5inco/Mesh with the code export assuming you are using the same Modifier recipe

i love sqlite!

Trying out Junie AI coding agent (jetbrains.com/junie/) from @jetbrains.com .....very impressive so far!

If you want to participate in a naming battle, here's your chance! I'd even say it might have an effect similar to deprecating String.capitalize(), but this time with a (hopefully) properly-named replacement

We're reworking one of the sharp edges of kotlinx.coroutines, the `withTimeout` function, which is useful, but has a few funky cancellation corners. 👉🏼 We need a name for the improved replacement function! What would you suggest as a name? (e.g. I'm a fan of `withTimeLimit`!)
