Sqliteman Portable can run from a cloud folder, external drive, or local folder without installing into Windows. It's even better with the PortableApps.com Platform for easy installs and automatic updates.
From the publisher: "The best developer's and/or admin's GUI tool for Sqlite3 in the world. No joking here (or just a bit only) – it contains the most complete feature set of all tools available. And much more – it's available for all major platforms, and it's free. If you are looking for a tool for tuning SQL statements, manage tables, views, or triggers, administrate the database space and index statistics – then Sqliteman is the perfect choice."
