# Free Data Explorer for MySQL and PostgreSQL Migration Checks

**[DBconvert](https://daily.dev/sources/dbconvert)** · 5 min read · 0 upvotes · 0 comments

## Summary

DBConvert Streams offers a free Data Explorer tool for inspecting MySQL and PostgreSQL data before and after migration or sync runs. It fills the gap between a migration tool reporting success and actually verifying the data landed correctly. The tool supports MySQL, MariaDB, PostgreSQL (including managed services like RDS, Aurora, Cloud SQL), plus local CSV, JSON, JSONL, Parquet files, and S3-compatible storage. Key features include schema browsing, a SQL console with query history, and staged inline editing. A typical use case is opening source and target tables side by side to compare row counts, spot value mismatches, and validate data integrity without writing custom verification scripts.
