Firebird has no problems with its license. You can use it in a commercial
setting without paying anything. And it can be used embedded (serverless).
In fact you can choose whether you want a sever installation (called
superserver) or embedded (called classic). In the embedded case it only
needs a lock manager process running to manage the locks when more than one
process opens the same database. I don't know if you can get rid of the
lock manager process if the database is only accessed from a single
With Firebird you do have all the transaction stuff.
