Liquibase is truly open-source and is released under the Apache 2.0 license. While Liquibase already supports a broad range of database platforms, it has a flexible extension framework for easily adding support for new database platforms. Additionally, it is easy to embed and execute Liquibase through its Java APIs.
When using the Liquibase model, Liquibase generates database-appropriate SQL. This allows teams to efficiently scale by writing database changes once and deploying to a variety of backends. Even if your team works with a single database platform, this capability standardizes the SQL produced in development making reviews, audits, and troubleshooting easier.

Liquibase has a robust set of capabilities to precisely control when, where, and how database changes are deployed. Go beyond filenames and precisely order changes with an explicit changeLog file. Fine tune how your changes are deployed to each environment with contexts and labels. Use conditional logic to further manage the deployment of changes in each environment with Liquibase preconditions.
Liquibase is built to support teams of developers working simultaneously on database changes, and can gracefully handle branching and merging of database migrations. There are numerous options for fitting Liquibase into a build processes. It is possible to generate SQL scripts for DBA code review and even perform database diffs. Liquibase does not require a live database connection, and makes it easy to document datbase migrations. Whether you are a DBA, QA Engineer, Release Manager, or Developer, Liquibase can meet your needs.
