What is SQLStudio?
SQLStudio is EverydayHub's free browser database toolkit at everydayhub.app/SQLStudio. It ships ten focused tools for SQL and NoSQL workflows — without accounts, uploads, or tracking.
Every operation runs locally in your browser. Queries, schemas, CSV files, and SQLite databases never leave your device.
Tools by category
Format & Convert
- SQL Formatter — beautify SQL with dialect-aware indentation
- SQL Minifier — compress queries and compare byte savings
- CSV → SQL — generate CREATE TABLE + INSERT from CSV
- JSON → SQL — turn JSON arrays into INSERT statements
Query & Explore
- SQLite Browser — open .db files and run SQL locally
- Query Builder — assemble SELECT queries visually
- EXPLAIN Visualizer — turn EXPLAIN output into a readable plan

- ER Diagram Generator — diagram tables from DDL
- Mock Data Generator — create realistic test rows
- Mongo Playground — try find/aggregate pipelines offline
Why browser-local SQL tools matter
Production dumps, customer extracts, and draft schemas often contain sensitive data. Cloud SQL playgrounds require uploads. SQLStudio keeps processing on-device so you can format, explore, and prototype safely.
