JetBrains
Companies
A company founded in Prague in 2000 that makes the IntelliJ IDEA, PyCharm, WebStorm and other IDEs, plus the Kotlin language. Its own coding agent Junie works in the IDE and the terminal; Claude Agent and Codex are built into the IDE next to it, and other agents connect through the open ACP protocol. Code completion runs on its own Mellum model. Air is a workspace where several agents run in parallel (preview).
