Git-like version control for data lakes over your existing object storage.

Open-source data version control that turns object storage (S3, GCS, Azure Blob, MinIO) into Git-like repositories. Teams branch, commit, merge, and roll back petabyte-scale data lakes for isolated experimentation, reproducible ML pipelines, data-quality gates, and compliance lineage — without copying data. Integrates with Spark, Trino, Databricks, Delta Lake, and Iceberg.

Open-source platform for the ML and GenAI lifecycle.

MLflow is an open-source platform for managing the full machine-learning and GenAI lifecycle — experiment tracking, model registry, deployment, and, more recently, LLM/agent observability. Its GenAI stack adds OpenTelemetry-based tracing, systematic evaluation with built-in metrics and LLM judges, and prompt versioning. Framework- and provider-agnostic, it runs on your own infrastructure with no vendor lock-in.
