YouTrack is a proprietary, commercial browser-based bug tracker, issue tracking system, and project management software developed by JetBrains.

[2][3] YouTrack's Ajax-based user interface allows both keyboard and mouse interaction.

[5][better source needed] The frontend is written in JavaScript, while the backend relies on Kotlin, a programming language created by the same software house.

[citation needed] For remote procedure calls, YouTrack supports a RESTful API.

JetBrains offers YouTrack in cloud-hosted and on-premises versions.
