We recently launched DeepData by Zorozo (https://deepdata.zorozo.com/) , a desktop app designed to make it simple for developers and analysts to join, preview, and export data across different database types specifically SQL (like MySQL/MSSQL) and NoSQL (like MongoDB).
Our biggest motivation was eliminating the frustrating, multi-step process of exporting, transforming, and re-importing data just to compare customer records in SQL with user behavior in MongoDB. We built an app with a drag-and-drop playground to solve that specific headache.
A developer tool to seamlessly access, query, and join data from multiple databases (SQL, NoSQL, etc.) without building complex ETL pipelines. Get your data faster, with fewer headaches.
