GoLand 2017.3 available for download

Why settle for just IntelliJ IDEA 2017.3 when you can also have GoLand 2017.3? We “warned” you last month that this moment would come and now it’s finally here. You can now download and/or purchase GoLand.

JetBrains’ Andrey Cheptsov explained in a recent blog post that in addition to Go-specific in-editor coding assistance, GoLand also offers a built-in test runner, test coverage, and a debugger. There’s also support for Git, Docker, databases, and more. Check out the list of features here

GoLand is aimed at offering the same level of developer experience for Go as PyCharm does for Python or IntelliJ IDEA does for Java. GoLand provides clever completion, on-the-fly inspections and quick-fixes, navigation and automated refactorings – all packed together inside an ergonomic environment.

Keep in mind that the IDE is available free for selected groups including students, teachers, and non-commercial Open Source projects.

There will be three major updates per year: spring, summer, and winter. Are you ready to give it a go?
