Advertiser disclosure: iTechGuides is reader-supported. Vendors can pay for top positions in our rankings and for a place on other products' pages, and we may earn a commission when you click some links. Bought places stand at the number bought; this page and our disclosure say so. Paying vendors may get a fuller, more detailed review from our editors, and that review can change their score.

Our review
Pros
  • Supports embedded, client/server, mixed, disk-based, and in-memory modes
  • JDBC support plus integrations with Hibernate and PostgreSQL client protocol
  • Includes encryption, clustering, transactions, and SQL-based backup commands
  • Embedded replicas support replicated databases inside applications
  • SQLite API and SQL dialect compatibility ease migration
