Frequently Asked Questions

What is a Cassandra GUI?
A Cassandra GUI is a visual desktop client that lets you browse keyspaces, run CQL queries, and inspect tables without using cqlsh on the command line. 1bench is a modern Apache Cassandra GUI for Mac, Windows, and Linux.
Does Cassandra have a GUI?
Apache Cassandra ships only with cqlsh, a command-line shell. For a visual interface, you install a third-party Cassandra GUI like 1bench — a desktop app that lets you explore keyspaces, inspect rows, and run CQL from one interface.
What is the best Cassandra GUI for Mac, Windows, or Linux?
A good Cassandra GUI should run natively on your OS, support username/password auth and TLS, and let you browse keyspaces, inspect tables, and run CQL without leaving the app. 1bench delivers all of this with a single download for Mac, Windows, and Linux.
Can a Cassandra GUI connect to managed Cassandra and self-hosted clusters?
Yes. Any Cassandra GUI that speaks the native CQL protocol works with managed Cassandra services and self-hosted clusters alike. 1bench connects using your contact points, credentials, and TLS, and supports SSH tunnels for clusters inside private networks.
What is the difference between cqlsh and a Cassandra GUI?
cqlsh is a terminal shell that runs CQL and prints text results. A Cassandra GUI like 1bench adds a visual keyspace browser, row and column inspection, a CQL editor with syntax highlighting, and inline row editing — so you can work with tables the way you do in a relational GUI.

Not Just Cassandra

One tool for all your databases. No more juggling apps.
