GoLand

JetBrains' GoLand (https://www.jetbrains.com/go/) is my personal favorite. It follows the great tradition of IntelliJ IDEA, PyCharm, and other great IDEs. This is a paid version with a 30-day free trial. There is no Community Edition, unfortunately. If you can afford it, I highly recommend it. If you can't or don't want to pay for an IDE (totally reasonable), check out the other options.
