Straight to your database, nothing in between.

Built for Cassandra

1

Full Keyspace Hierarchy

Browse keyspaces, tables, and materialized views in your Cassandra cluster. Replication strategies and consistency levels visible per keyspace.

2

Visual CQL Editor

Write CQL with syntax highlighting, autocomplete for keyspaces, tables, columns, and inline error reporting. Multi-statement execution.

3

Row-Level Editing

Browse table data as a paginated grid or as row-detail cards for wide column-family schemas. Cells edit inline, changes stage before commit.

4

Create Tables with Cassandra Semantics

Visual wizards for tables (partition keys, clustering columns, custom types, TTL settings, compaction), all with live CQL preview.

10x your Cassandra productivity

Stop switching between CLI and code. Manage everything visually.

CQL Editor

Write and execute CQL queries with syntax highlighting, autocomplete, and inline error reporting.

Visual Query Builder

Build SELECT, INSERT, and UPDATE queries visually with a searchable schema tree. No CQL syntax guessing.

Keyspace Browser

Browse keyspaces, tables, and materialized views. View replication strategies and settings at a glance.

Create Table

Create tables with partition keys, clustering columns, and custom types through a visual interface.

Drop Table

Remove tables safely with typed confirmation and dependency warnings to prevent accidental data loss.

Import Data

Import data from CSV and JSON files. Map columns and configure batch sizes during import.

Export Data

Export query results or entire tables to CSV or JSON. Filter and project from the export dialog.

Token Range Visualization

Visualize token ranges and data distribution across nodes. See replica placement per key range inline.

Autocomplete

Smart suggestions for keyspaces, tables, columns, and CQL keywords as you type. Learns from your schema.

Keyboard Shortcuts

Navigate tables, run queries, switch tabs, and manage connections without ever reaching for the mouse.

Multiple Tabs

Work across Cassandra keyspaces and connections in parallel. Each tab keeps its own browsing state.

Query History

Every CQL query you run is saved per connection. Search, filter, and re-run previous queries instantly.

Production Safe

Read-only mode, destructive-action confirmations, and per-connection ACL checks keep production safe.

SSH Tunnels

Connect to remote Cassandra clusters through SSH tunnels and bastion hosts. Reads ~/.ssh/config.

DataStax Astra Support

Connect to DataStax Astra cloud databases with secure connect bundle authentication and TLS.

Not just Cassandra

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

Cassandra GUI FAQ

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.
