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.

Curate, annotate and QA multimodal training data in one governed workspace
Annotate image, video, audio, text, documents, medical imaging, pathology, geospatial, sensor and tabular data in one governed workspace rather than stitching together separate tools.
Bring your own models into the labeling loop for pre-annotation, segmentation and object tracking, with multiple model stages combined with human review before anything is approved.
Consensus, Quality Gate and expert review stages validate labels against hidden answer keys to keep training data reliable — Unitlab cites 99%+ QA-backed accuracy.
Build dataset versions as data evolves, assign tasks, track changes and keep annotation history and label lineage auditable across the AI lifecycle.
