## What it is
lakeFS is an open-source data version control service that turns object storage (S3, Azure Blob, GCS) into a Git-like repository with branching, committing, merging, and rollback over data lakes. It is S3-API compatible, works with Spark, Athena, DuckDB, Presto, and pandas, and provides zero-copy isolated branches for ETL testing and AI agent workflows.

## Use cases
- version control for data lake on S3
- test ETL jobs in isolated dev branch before merging to production
- roll back bad data loads atomically
- give AI agents isolated zero-copy branches of production data
- reproducible snapshots of training data
- manage data quality checks with hooks before merging
- query data lake with Spark or DuckDB against versioned branches

## When to choose
- you run a data lake on S3, Azure Blob, or GCS and need Git-like branching, merging, and rollback over data
- you need isolated dev/test environments for ETL without copying data
- you want reproducible, auditable data versions for analytics, ML training, or AI agents
- you want an S3-compatible API so existing data tools work unchanged

## When to avoid
- your data lives in a traditional database rather than object storage
- you only need simple file backups or sync rather than versioned data operations
- you need row-level versioning inside a single table rather than object-level lake versioning
- you cannot operate an additional self-hosted service or prefer a fully managed warehouse
