Schemezy

Schemezy is a straightforward web tool for documenting NoSQL database schemas. It focuses on MongoDB and Firebase Firestore, two of the most popular document databases. Instead of writing formal schema definitions by hand or juggling spreadsheets, you open Schemezy in your browser and start building collections and fields visually.

The interface is minimal: you add a root collection, then define fields within it. Schemezy doesn't try to guess your schema — it gives you a blank canvas to design exactly what your app needs. You can import sample schemas to see how it works or to use as a starting point. The tool also supports exporting your schema, which is handy for documentation or sharing with teammates. A help dialog explains the basics if you get stuck.

Schemezy is best for backend developers and database architects who need a quick, no-fuss way to sketch out a NoSQL schema before writing code. It's also useful for documenting an existing database for team reference. If you're planning a new project or need to communicate your data model clearly, Schemezy gets the job done without unnecessary complexity.
