Built this because annotation teams working on serious AV/robotics datasets often can't send data to a third-party cloud, and existing self-hosted options have no real multi-user workflow.

Runs on Docker + PostgreSQL. WebGL renderer handles 1M+ points at 60fps in the browser. Full annotator/reviewer/admin roles with a review pipeline, issue tracking, and audit trails. Supports local filesystem or S3-compatible storage.

Happy to answer questions about the rendering approach or the multi-user architecture.
