When news broke that SpaceX would acquire Cursor's parent company, Anysphere, in a reported $60 billion all-stock deal, most of the discussion centered around AI. This was another milestone and enormous valuation, and signal that AI is still bringing enormous disruption. Those reactions aren't wr…

We evaluated coding agents across the JVM, .NET, and Python – and Codex was the winning agent.

Starting with the Toolbox App 3.6 Early Access Program (EAP), SSH connections to remote environments use the JetBrains Daemon (jetbrainsd) by default. We’re making this change available in the EAP first because jetbrainsd is becoming the shared background service for JetBrains tools. Moving SSH t…

Imagine there’s a stranger out there who has nothing but API access to your chatbot. They are interested in knowing whether a specific patient, employee, or customer appears in the data you trained it on.

At the JetBrains x Codex Hackathon, I spent two days watching teams build and then pitch their projects. The thing that decided most of the winners wasn't just the previous twenty-four hours of work. It was the few minutes they spent presenting it. A strong project with a confusing demo loses to a s…

Our ROI (return on investment) calculator was designed to help estimate the potential gains of JetBrains IDEs and AI Ultimate subscriptions.
