Which apps read/write an SQLite 3 database in Ubuntu?

Check out Beekeeper Studio. It's MIT licensed, works great with SQLite and can handle MySQL, PSQL, SQL Server as well.

My friend and I built it because we wanted a more modern feeling and easier to use SQL editor that worked for all database types.

I use it every day. Hope others like it too.

Take a look at SQLite Studio. Despite it is not available in Ubuntu packages repositories, it works perfectly well on this OS and is free and open-source.

The project is maintained since 2007 (as of 2018). It's multiplatform, feature rich and can be extended by plugins.

Full history is available if you feel like curious.

Try DB Browser for SQLite. From the site:

DB Browser for SQLite is a high quality, visual, open source tool to create, design, and edit database files compatible with SQLite.

It is for users and developers wanting to create databases, search, and edit data. It uses a familiar spreadsheet-like interface, and you don't need to learn complicated SQL commands.

Controls and wizards are available for users to:

• Create and compact database files
• Create, define, modify and delete tables
• Create, define and delete indexes
• Browse, edit, add and delete records
• Search records
• Import and export records as text
• Import and export tables from/to CSV files
• Import and export databases from/to SQL dump files
• Issue SQL queries and inspect the results
• Examine a log of all SQL commands issued by the application

Install with sudo apt install sqlitebrowser

There is an application in the repositories for Ubuntu versions before 18.04 called sqliteman. It is listed in those repositories as "GUI tool for SQLite3 admin and developers alike".

I haven't used it much but it seems like it's a readily available GUI tool in the repositories. If you are using a version of Ubuntu earlier than 18.04, you can install it with apt-get install sqliteman.

A method would be to use mozilla's firefox plugin called sqlite manager:
