Git hosting and CI/CD for teams that live in Jira
Host unlimited private or public repositories with branch permissions, merge checks and inline code review.
Run CI/CD in the cloud or on private runners with pipeline configuration, deployment environments and centralized visibility.
Link commits, branches and pull requests to Jira issues to trace every change from requirement to production.
Atlassian's AI agents assist with code review, pipeline triage, onboarding to a codebase and converting Jira items into code.

The teaching layer that explains every line your AI coding agent writes
Every line your agent writes is explained as it happens, covering what the code does, why it was written that way and the intended goal, in the same window.
A VS Code extension brings the teaching layer to Cursor, Copilot, Claude Code, Codex CLI, Cline, Kilo Code, Windsurf, Antigravity and more without changing your agent.
Plan, Fast, Deep and Recursive modes let you propose before writing, iterate quickly, reason deeply, or let the recursive agent plan multi-step work.
49+ prerequisite-locked topics, projects, graded checkpoints and boss exams inside the IDE, with a hint economy earned by completing topics.
