A student can request their free subscription at, and then renew it annually for free until they graduate. Upon graduation, JetBrains provides all the students with a 25% graduation discount.

From the very start of the JetBrains Student Program, we have offered three options to prove eligibility for a free educational license: an email address in a domain which is known by JetBrains as belonging to an educational institution, an ISIC card, or an official document which proves that you are a student.

We are happy to announce a new, fourth, option today, which aims to help make it simpler and more widely available for students to get their free JetBrains Student Packs.

Free educational JetBrains license is now a part of GitHub Student Developer Pack

Many students from around the world benefit from the GitHub Student Developer Pack, which GitHub created with some of their partners and friends to give students free access to the best developer tools.

Effective as of today, everybody who has a GitHub Student Developer Pack can get a free JetBrains Student Pack, which gives a free year-long subscription to all the JetBrains desktop tools, including IntelliJ IDEA Ultimate, PyCharm Professional, CLion, and Rider.

If you do not have a free JetBrains Student Pack yet, but have your GitHub account which GitHub has already verified as belonging to a student, please open the GitHub Student Developer Pack page (, click on the card with the JetBrains logo, and authenticate with your GitHub credentials. You will be guided to a page on the JetBrains website where you can request your free educational license for JetBrains tools, you will get a series of two messages from the JetBrains team asking you to confirm your request and then to activate your educational JetBrains license.

Celebrating the Drive to Develop on Programmers’ Day 2018

Last week on the 256th day of the year individual developers and organizations all over the world celebrated International Programmers’ Day.

We, at JetBrains, with so many incredible developers around us couldn’t just sit back and let this day pass without some kind of recognition. We asked all the programmers who follow us on social media (mostly Twitter) to use the hashtag #MyDriveToDevelop and tell the world what programming meant to them – what was their “Drive To Develop”.

Programmers' Day 2018

As for the results, developers from over 25 countries on all of the continents (with the exception of Antarctica) posted their own personal stories.

We want to thank everyone who took part, we read every single one of the #MyDriveToDevelop hashtag tweets and comments and were truly fascinated by how much the programmer profession means to so many of you.

It would be impossible to share all the comments in this blog post and also unfair to post just a few and call them the best because all of the tweets and comments were amazing, full of warmth and consideration. So what we’ve done is prepare this cloud of words to depict the most frequently used words and give you an insight into what drives developers with their work.

Programmers' Day 2018: cloud of tweets and comments
If you want to read all the original tweets just browse Twitter, Facebook or VK with the #MyDriveToDevelop hashtag.

Each and every programmer has their own #MyDriveToDevelop, however there are some commonalities that we’ve noticed.

Making a difference
Creating opportunities, simplifying the processes, building something that others find valuable.

Collaborating with others
Connecting the community, making cool things together, sharing knowledge with others, helping other developers to achieve the goals they have.

Being a challenger
Staying curious and hungry to experiment, improve and constantly evolve. Turn routine into fun and complexity to simplicity.

Being a dreamer
Making dreams come true, turning ideas into things that have a purpose.

Being a superhero
Having unlimited possibilities, solving complex real life problems, improving everyone’s life, making the world a better place with help of the software!

With the Drive To Develop nothing is impossible.

We at JetBrains could not agree more, all the things people mentioned about why people love programming, all resonate deeply with all of us in this incredible field of work. There is something that drives us as programmers to seek out the challenges, make solutions, and have an impact on the world, regardless of where you are in the world. We are just so glad to have a community of similarly driven people.

Stay passionate, stay curious, and may your #MyDriveToDevelop always be with you!

The Drive to Develop

PS: At JetBrains, we celebrated the Programmers’ Day not only online but also offline, in the company of great colleagues in each of the JetBrains offices. We had some snacks, drinks, and games. And of course cake!

Programmers' Day 2018: cake

Toolbox App 1.11: What’s New.


Download now

Ever since Toolbox App 1.0 first came about back in October 2016, more and more of our customers are finding that using it makes it even easier for them to access their projects across JetBrains IDEs and update all their IDEs to the newest versions (including EAPs). We want to thank you for supporting and encouraging us to make Toolbox App even better.
Based on your feedback we developed and launched the following features in our previous releases:

  • Auto-update for Toolbox App is now enabled by default
  • Toolbox App can update manually installed IDEs on all OS
  • Option to disable instant rollbacks


  • Command-line launchers (Shell scripts) for installed IDEs


And now we have better integration into all the different OS

  • Linux: Toolbox App detects IDEs which were manually installed.
  • Windows: run the IDEs as Administrator, IDE shortcuts in the Taskbar and on the Desktop are updated automatically.
  • macOS: fixed the bug where docked icons were broken after an upgrade (Dock restart was required after each update).


What’s new in Toolbox 1.11

Well, it’s now time for something new. We understand how important it is for you to see the release notes before installing the version updates. Please find the What’s New in the new 1.11 Toolbox App release. Review the release notes before you update right inside the app as soon as a new version update becomes available.

Updated UI

We have also updated the Settings UI by removing the “apply” button. All changes are now applied immediately.

This release comes with the usual batch of bug fixes as well. The most noticeable of which is that Gradle support now works correctly in IntelliJ IDEA when started from Toolbox App on Windows. See the full list of release notes.

We love your feedback and will continue improving Toolbox App to make it more reliable for you. Follow us on Twitter to get the latest up-to-date news and useful tips.

Educational Products 2018.2: Scala and Project-Based Learning

Riding the 2018.2 release wave that has recently hit our IDEs, we’re also updating our Educational Products so that your everyday learning and teaching is full of even more joy and the drive to spread knowledge.


Scala is now supported

We’re happy to welcome Scala as the next programming language supported by our Educational Products. Educators can now share their Scala knowledge in the form of coding tasks and custom verification tests, the same they do for Java, Kotlin, and Python.

Unfortunately, we don’t have any Scala courses yet. We need your help!

If you’re an educator, please take a look at the Quickstart Guide and try to create your own course. If you need our support or want to help create Scala learning materials, please let us know. If you’re a learner, do share your favorite Scala learning materials with us! Just leave a comment here or contact us on Twitter.

Project-based learning, first steps

Project-based learning is about making something real, driving results that help learners stay engaged and motivated. We believe it is of paramount importance especially in learning programming. In this release, we’ve implemented Framework Lessons which is is the first step towards making project-based learning a first-class approach supported by our Educational Products.

JetBrains 6th Annual Hackathon: Shiftius Altius Ctrlius


The Hackathlon

“Don’t put a limit on anything. The more you dream, the further you get.” — Michael Phelps, winner of 23 Olympic gold medals

Faster. Higher. Stronger.

The stage was set for the event of the year; the coveted JetBrains hackathon.

The rules were very simple:

  1. The Hackathon starts on Wednesday, June 27, at noon sharp CEST and runs for 48 hours.
  2. The last commit is allowed no later than Friday, June 29 noon CEST. Presentations must be provided to the Org.Committee by this time as well.
  3. 5-minute presentations will start 1 hour later, at 13:00 CEST on the same Friday.
  4. Everyone at JetBrains can cast votes for the projects they loved.
  5. Winners get prizes.


Facilitated by a wiki page, ideas and concepts could be put forth, and potential partners found. After the date announcement, in the weeks leading up to the event, like-minded people eager to compete and bring to life their burning ideas formed the teams they would need to make this possible.
54 project ideas were entered from 125 participants. This was already a 25% increase in the number of people from last year.

On the start day, the registration opened at 10am providing the Hackatheletes with all the necessary gear they would need to get through the two days: toothbrush; washcloth; sports drinks; energy bars; t-shirt; badges and stickers.


48 projects showed up at the start line. With only 48 hours to go, teams had no time to spare if they were going to get their ideas working and ready for demo.

A Chat with Jonathan Worthington, Creator of Comma, a Perl 6 IDE Built on Top of the IntelliJ Platform

In this interview we speak with Jonathan Worthington (@jnthnwrthngtn), Edument team member and creator of Comma IDE. Comma is an Integrated Development Environment for the Perl 6 language, built on the IntelliJ Platform.

Jonathan Worthington

Welcome Jonathan. Could you please tell us a bit about yourself and your role at Edument?

I started at Edument in 2010, as the first employee. I spent my first five years at Edument working in Sweden, doing a mix of teaching and consulting. These days, I’m living in Prague, and have started a new Edument office here. I’ve been taking a much-needed break from teaching and have been enjoying focusing more on consulting and building products.

A few years before joining Edument, I got involved with Perl 6 development. Back then, there was a lot of skepticism over whether the language would ever reach a stable specification and a production implementation. I’d been especially interested in compilers, runtimes, concurrency, and language design during my time at university. Perl was at the heart of my first business, started when I was a teenager, and I delivered numerous web application projects using it. So, helping with Perl 6 felt like a nice way to give back to the community that had freely given me a tool that I used to make a living for many years.

And what a ride it’s been! Not just in that I came to play a key role in delivering the language and implementation, but every bit as much for the people I’ve had the pleasure to work with along the way.
