I'm looking for a SQLite graphical administration utility for Linux but I can't seem to find any (I found an extension for Firefox I'm not a user of that browser).
Is there any that you know of?
Tried Sqliteman? Look for
sqliteman in your package manager. It is stable, so should be broadly available.
I've been using
sqlitebrowser, it is a really good options. Though probably not the only one!
On Ubuntu, it is available in the default package repositores.
I've used the SQLiteStudio for working with sqlite3 database. It looks very well.
The project is maintained (as of 2018). For some reason it is not available in common packages repositories.
You can use for this purpose Valentina http://www.valentina-db.com/valentina-studio-overview, the program is free. It works on 3 OS: LIN, MAC, WIN. It works as with mySQL/mariaDB, so with PostgreSQL, SQLite and Valentina DB.
I have not used this yet but looks promising especially if you're looking for a web-based interface.
You can try Sqlite Manager Firefox Add-on.
