IntelliJ IDEA 20 years

Today we’d like to take a moment to thank you, our amazing users. IntelliJ IDEA wouldn’t be where it is today without you and the valuable feedback you provide!

Thank you for being with us, and let’s celebrate this milestone together!

IntelliJ IDEA Conf is over.
Please join us next time!

IntelliJ IDEA Conf was a free virtual event that we held on February 25–26, 2021, to celebrate IntelliJ IDEA’s 20th anniversary.

The creators of IntelliJ IDEA talked about its incredible features and provided the inside story on the evolution of IntelliJ IDEA, and our experts shared tips, tricks, and best practices for becoming a more productive developer.

We've made recordings of the talks that you can view whenever you like.
