Data lineage made simple. Grai makes it easy to understand how your data relates together across databases, warehouses, APIs and dashboards.

• Pre-built connectors. Automatically synchronize lineage from across the stack so your metadata is never out of date.
• Centralized data tests. Write data validation tests which run whenever upstream data sources change (coming soon).
• Integrated with git. Run data validation tasks as part of your CI/CD process to test changes everywhere you data is used. No coordination meetings required.
• Your data, your cloud. Grai is fully open sourced and self hosted. You maintain full control over your data and hosting environment.

git clone https://github.com/grai-io/grai-core
