Liquibase vs Sequelize: What are the differences?
What is Liquibase? Source control for your database. Developers store database changes in text-based files on their local development machines and apply them to their local databases. Changelog files can be be arbitrarily nested for better management.
What is Sequelize? Easy-to-use multi sql dialect ORM for Node.js & io.js. Sequelize is a promise-based ORM for Node.js and io.js. It supports the dialects PostgreSQL, MySQL, MariaDB, SQLite and MSSQL and features solid transaction support, relations, read replication and more.
Liquibase and Sequelize are primarily classified as "Database" and "Object Relational Mapper (ORM)" tools respectively.
"Great database tool" is the primary reason why developers consider Liquibase over the competitors, whereas "Good ORM for node.js" was stated as the key factor in picking Sequelize.
Liquibase and Sequelize are both open source tools. It seems that Sequelize with 19.2K GitHub stars and 3.01K forks on GitHub has more adoption than Liquibase with 1.78K GitHub stars and 1.09K GitHub forks.
WebbyLab, Decision6, and Hostr are some of the popular companies that use Sequelize, whereas Liquibase is used by Viadeo, Orbitz, and Virgin Pulse. Sequelize has a broader approval, being mentioned in 38 company stacks & 33 developers stacks; compared to Liquibase, which is listed in 15 company stacks and 12 developer stacks.

Flyway vs Liquibase #Migration #Backwards-compatible
We were looking for a tool to help us integrating the migration scripts as part of our Deployment. At first sight both tools look very alike, are well integrated with Spring, have a fairly frequent development activity and short release cycles.
Liquibase puts a lot of emphasis on independence with the DB, allowing you to create the scripts on formats like JSON and YML, abstracting away from SQL, which it's also supported. Since we only work with one DB type across services we wouldn't take much advantage of this feature.
Flyway on the other hand has the advantage on being actively working on the integration with PostgreSQL 11, for it's upcoming version 6. Provides a more extensive set of properties that allow us to define what's allowed on what's not on each different environment.
Instead of looking for a tool that will allow us to rollback our DB changes automatically, we decided to implement backwards-compatible DB changes, for example adding a new column instead of renaming an existing one, postponing the deletion of the deprecated column until the release has been successfully installed.
