description Connect Galaxy to your data stack

Sources are connections to external data systems. When you connect a Source, Galaxy observes its structure and replicates data according to your configuration.

What Sources Are

Sources are the underlying systems of record that supply the raw data used to construct your Project.

When you connect a Source, Galaxy observes the structure of your connected systems: schemas, tables, columns, files, folders, and organizational elements. Galaxy automatically manages a data infrastructure built on Apache Iceberg that replicates and stores your data.

Galaxy supports both structured and unstructured data:

  • Structured sources: Databases, spreadsheets, and other structured formats expose schemas, tables, columns, and relationships
  • Unstructured sources: Documents, files, and text content are processed to extract structure, text, entities, and semantic information

Source Types

Galaxy supports the following Source types:

  • File Upload: Direct file upload to Galaxy
  • Browserbase: Website content scraping
  • Free Text: Paste or type content into the input box
  • COMING SOON PostgreSQL: Relational database management system
  • COMING SOON Google Drive: Cloud-based file storage and collaboration platform
  • COMING SOON Slack: Messaging and collaboration platform
  • COMING SOON Amazon S3: Object storage service
  • COMING SOON Notion: Productivity and knowledge management platform
  • COMING SOON Attio: CRM platform

Each Source type has specific configuration requirements. See the individual Source pages for detailed information.

Managing Sources

![Source Details](/images/source-details.gif)

After connecting a Source, you can:

  • View structure: Browse schemas, tables, columns, files
  • View activity: See all syncs and updates to the source from your team
  • Sync: Update Galaxy’s understanding if the source system has changed
  • Configure connection: Update connection details or authentication
  • Delete: Disconnect a Source if it is no longer needed
Removing a Source does not delete Projects, but Projects that were using that Source will no longer have access to its structure.

Sources and Projects

Galaxy intentionally separates observation from interpretation.

Galaxy connects to systems and records what exists Teams define what those structures mean in context As nodes and edges are defined, a navigable graph forms When systems change, the context graph can evolve with them

Multiple Projects can attach to the same Source. This allows different teams or use cases to interpret the same Source structure differently, depending on their needs.

Don’t see a source type you're looking for? We connect to hundreds of systems - reach out to [support@getgalaxy.io](mailto:support@getgalaxy.io) to request access.
