are completely portable. You can move the file between computers running LocalDB.
The host machine must have the LocalDB runtime installed, though the footprint is much smaller than the full engine. Method 2: Docker Containers (Best for True Portability) ms sql server express portable
Yes. SQL Server Express is free to use and redistribute. However, you must adhere to Microsoft's licensing terms. Generally, as long as you are using it for development or small-scale applications and not reselling the database engine itself, running a portable instance is within the bounds of the license. are completely portable

The first test at home succeeded: the Node app connected, queries ran, and he could demonstrate transaction rollbacks to his cat's unconcerned approval. The next weekend at the center, however, taught him the limits of "portable." The center's Windows accounts restricted installs and blocked services. LocalDB required per-user registration and some components couldn't be run from removable media without write access.
installer won't work on a thumb drive without installation, consider these three paths: 1. SQL Server Express LocalDB (The "Developer" Portable)
These wrappers install a minimal instance of SQL Server into a specific folder. When you launch the "Portable" executable, a launcher script silently installs the necessary services into the Windows Temp folder, starts them, and allows you to use the database. When you close the application, the script stops the services and removes them.
