DBLens is a free and open-source PostgreSQL client with database performance metrics and disk usage. Here this is a powerful PostgreSQL editor that you can use to quickly connect to a database, run SQL, browse through database tables, and see the database system perforce on a dashboard. It lets you connect to multiple databases as well, both local and remote ones.

We have covered PostgreSQL editors before, but this one here is a nice one to have, especially if you also want to keep an eye on how well your database is performing. Apart from feeding and retrieving data from the database, you can see the index and table hit rate. You can see the size of the tables on the disk and statistics about the longest running queries.

There are some other details that it shows you graphically for you to analyze. If you have a large PostgreSQL database that you use frequently, then the database metrics that it shows will help you tune or optimize it. For now, you can use DBLens on Window and macOS, but I hope there will be a release in the future for Linux systems as well.
