Variety is a lightweight schema analyzer for MongoDB that runs via the mongosh/mongo shell or Node.js. It scans collections to reveal the document structure, field frequencies, value types, and rare keys or schema outliers.

Use cases

  • analyze the schema of an unknown MongoDB collection
  • discover rare or outlier fields in a MongoDB database
  • learn the data structure of an inherited codebase's data dump
  • profile BSON types present in MongoDB documents
  • document field coverage across a MongoDB collection

When to choose

  • you work with MongoDB and need a quick, lightweight schema overview without a GUI
  • you inherited a dataset and want to understand its structure fast
  • you need to find rare keys or inconsistent fields across documents

When to avoid

  • you use a database other than MongoDB
  • you need a persistent GUI-based schema explorer or data modeling tool
  • you need continuous schema validation or enforcement rather than one-off analysis
