We are working on extensions to our companions mechanism to unlock new code patterns and improve interoperability across different platforms. This post outlines these new features and provides preliminary guidance on migration.
What is Small Talk? Small Talk is our short Q&A with founders from the JetBrains Startup Program. They answer a handful of questions in their own words about what they’re building, why they started, and what they’ve figured out along the...
Testing applications before release alone is no longer enough when it comes to quality assurance for modern software development. It needs a more dynamic approach that makes QA a part of the ongoing process.
In 2026, Kotlin turned fifteen. Over those fifteen years, Kotlin has built a mature ecosystem, been adopted by companies around the world, and established a large and active developer community.
Rider 2026.2.3 brings AI performance analysis to the Monitoring tool window and fixes an issue with the AI Agent Setup widget on Windows.
Today, we’re introducing JetBrains Air Teams – the team layer for agentic development. It gives humans and agents the shared context, environments, tools, and instructions they need to work effectively together across the full development...
The current compilation approach to Kotlin Multiplatform projects works, but sometimes can lead to unexpected or hard-to-predict behavior.
In this post, I’ll share how we designed and built the new TeamCity integration for Kotlin Multiplatform. Our guided onboarding helps KMP developers building for iOS go from their first Git push to a tested build, a TestFlight release, and...
A year ago, we introduced the first wave of PhpStorm’s open-source sponsorships. We truly believe in the power of open source and the importance of it to the PHP community, and so we want to do our bit, too.
100 Exercises to Learn Rust is our adaptation of Mainmatter’s course of the same name, written by Luca Palmieri, Principal Engineering Consultant at Mainmatter, and it has just received its biggest update since we released it a year ago.

AI can produce code. Organizations still have to produce software. Agentic development is changing how software gets made, but it hasn’t changed what it costs to be wrong.
Code quality is shaped by countless decisions, from how developers manage complexity to how quickly they detect regressions.
Ktor 3.6.0 is here! This release is full of new experimental features, including typed authentication capabilities with specialized support for OpenID Connect and HTTP/3 support for the Netty engine.
You have the change ready and the tests are green. Now someone has to launch the app, find the right screen, and check the flow. Often, that someone is still you, even when an agent helped write the code.
We want local coding agents to be smart and fast, with the ability to understand a codebase, do useful work, and finish tasks without long waits. This Junie Local update makes it practical to use a more capable model on your own machine.
We are living in genuinely interesting times. AI is disrupting software development at a pace where new models, tools, and practices appear almost daily. Many teams’ natural first instinct is to spend ever more time chasing updates.
