A developer in DevOps pushes a Kubernetes deployment with no resource limits, a pod running as root explicitly, and a GitHub Actions workflow runs with mutable tags – and it goes straight to production, unnoticed. No quality gate. No IDE warning. No CI failure. An innocuous change, silently shipped, but with high …

This PyCharm release is a big one for anyone building with AI. Your agents can now roll up their sleeves inside your Jupyter notebooks – working against a live kernel instead of firing off disconnected scripts.

AI agents are supposed to save you time. Ask one to install a dependency or run your project, though, and it often does the opposite: It installs into the wrong Python, ignores the uv or virtual environment your project uses, and hands back a broken setup for you to fix yourself. PyCharm’s new Agent Environment […] …

If you’ve handed notebook work to an AI agent, you know how it tends to go: More often than not, it corrupts your .ipynb, loses your trained model the moment the run finishes, or burns budget sitting idle through a long job while you watch. To solve this, we’re introducing a brand-new Jupyter skill. Built […] Link to …

When developers hear “AI in the IDE”, the first thing that often comes to mind is a chat window. IntelliJ IDEA includes an AI chat, but JetBrains AI features also appear in many other parts of the development workflow. Some of those features are easy to miss because they are built into existing IDE actions: […] Link to …

Frontend development has historically meant working in three separate environments: a design tool for specs and prototypes, the IDE for coding, and a browser to check if everything works. A few days ago, we released the new plugin Figma Connect for WebStorm, which eliminated the first context switch. Design intent, …

Somewhere between the fifteenth open tab and the third iced coffee, it hit me. Maybe we don’t hate meetings. We just hate the ones where nobody has anything to say. Welcome back to another mandatory meeting. This one’s got range: Kotlin just turned 15, IntelliJ IDEA Conf dropped a lineup worth clearing your calendar …

The simplest tools are often the most useful, and debugging is a prime example of this. There are many advanced debugging techniques, and while they all have their use cases, println debugging is still the #1 choice, whether you’re doing it manually or with the help of coding agents. Inserting a println statement to …

Where time actually goes in design-to-code Every design implementation starts the same way: find the Figma tab, find the right frame, screenshot it, paste it somewhere, switch back to the terminal. By the time you write the first line of code, you’ve already done five minutes of busywork, and you’ll do it again when …
