A complete database workspace

Everything your data work needs.

Engine-aware explorer

Browse schemas, tables, views, procedures, indexes, roles, Redis keys, and MongoDB collections with automatic refresh after structural changes.

SQL, MongoDB & Redis editors

Use syntax highlighting, formatting, autocomplete, selected-statement execution, timing, and engine-aware dangerous-command detection.

Powerful, safer results

Sort type-aware results, inspect JSON, edit SQL rows inline, mask detected PII, and confirm generated mutations before they run.

Type-aware cellsPII maskingMutation guards

Executable notebooks

Combine live query cells with GitHub-flavored Markdown, KaTeX math, tables, and highlighted code, then export to IPYNB, Markdown, or SQL.

Import, export & transfer

Preview and import CSV, JSON, or Parquet; export CSV, JSON, XML, or compressed Parquet; and copy tables between SQL databases.

Backup & scheduled exports

Run native PostgreSQL, MySQL, MariaDB, and SQLite backup workflows, or automate validated local exports with job history.

How it works

From connection to insight in minutes.

See every database in one organized workspace. Recent connections, saved notebooks, and pinned queries stay ready whenever you return.

  • Connect without creating an account
  • Keep every workspace local
  • Pick up exactly where you stopped

  1. 01

    Download & install

    Grab the native desktop bundle for macOS, Windows, or Linux. No account required, no telemetry.

  2. 02

    Launch the app

    Open NexusDB and pick up where you left off — recent connections, saved notebooks, and pinned queries are right there.

  3. 03

    Create a connection

    Add a local or remote database. Credentials are stored in your OS keychain, never in plaintext.

  4. 04

    Browse schemas & tables

    Use the engine-aware explorer to navigate schemas, tables, views, indexes, Redis keys, and MongoDB collections.

  5. 05

    Run SQL queries

    Compose queries in the tabbed workbench with syntax highlighting, formatted output, and timing per query.

  6. 06

    Export, import & manage

    Save results to CSV, JSON, or Parquet. Import data, schedule backups, and copy tables between databases.

Built for focused work

Explore and query without switching tools.

Move naturally from schemas and tables to a full query workbench. NexusDB keeps the database context beside your editor and results.

  • Browse schemas, tables, and collections
  • Run and format queries in tabs
  • Inspect typed results immediately

Secure by design

Your credentials belong to you.

Secrets live in your operating system's credential vault—not in frontend state. Filesystem access is restricted, certificates are validated, and risky operations require confirmation.

Protected at every layer
  • Credentials isolated in the backend
  • Query time and size safety limits
  • Dangerous command detection
  • Restricted filesystem permissions

Common questions

Everything you need to know.

Still have a question? Talk to us.

Is NexusDB really free?+

Yes. The core NexusDB desktop experience is free for individual developers, with no account required.

Where are my credentials and data stored?+

Your connections, credentials, and query history stay locally on your machine. NexusDB does not send your database data to a hosted cloud service.

Does NexusDB work offline?+

Yes. You can work completely offline with SQLite files or databases running locally in containers.

Which databases are supported?+

NexusDB supports PostgreSQL, MySQL, MariaDB, MongoDB, SQLite, Microsoft SQL Server, and Redis, with engine-aware browsing and query tools.

Can I copy data between databases?+

Yes. NexusDB lets you copy tables between SQL databases, schedule local exports, and run native backup and restore workflows.

Is my data safe?+

Credentials are isolated in the OS keychain, dangerous commands require confirmation, and the application never proxies your data through a third-party service.
