JetBrains Plugin Developer Conf 2026: AI, New APIs, and More

What does the rise of AI agents mean for plugin development? And what new tools and APIs can help you build better plugins for JetBrains IDEs?

These are some of the topics we’ll explore at JetBrains Plugin Developer Conf 2026, taking place online on November 10 at 1:00 pm UTC. Join us for a free day of technical talks, real-world examples, and live Q&A sessions with JetBrains experts and fellow plugin developers.

What’s on the agenda?

This year’s program covers AI-assisted plugin development, language support with LSP, new IntelliJ Platform tools and APIs, and practical lessons from building and maintaining plugins.

Here’s the full lineup:

• Opening Keynote by Ivan Chirkov, Yuriy Artamonov, Jakub Chrzanowski, and Róbert Novotný
• Dependency Assistant: An IntelliJ Plugin That Started With a Prompt by Mark Paluch
• Building Language Plugins With the Native LSP API by Vladimir Logachev
• Integrating a Web-Based Profiler Into IntelliJ IDEA by Johannes Bechberger
• Your Plugin’s Second Service: Architecture for Integrations That Grow by Evgeny Kudelevsky
• EelApi: Developing Plugins for Every Project Environment by Alexander Koshevoy

From exploring where AI helps (and where it doesn’t) to building language plugins, integrating web-based tools, and supporting different development environments, the sessions offer practical insights you can apply to your own projects.

You can attend the entire conference or tune in for individual talks.

The sessions will be streamed live on YouTube and available to watch afterward, so you can catch up on anything you missed. Bring your questions for the live Q&A sessions!
