One thing that Liquibase does better than Flyway is supporting multiple different database systems with the same migrations by abstracting the changes instead of relying on raw SQL statements such as Flyway.

Liquibase and Flyway are the only major frameworks on the JVM which could be embedded into a JVM application to get rid of a sidecar or a startup process which has to run before the actual application could start.

That's exactly why Liquibase turned source-available. These abstractions are leaky, error-prone and are better maintained via the money from support contracts.

"Make problem, they earn money fixing them" is a reasonable modus operandi.
