Sequelize vs Entity Framework Core: What are the differences?
Developers describe Sequelize as "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. On the other hand, Entity Framework Core is detailed as "*Lightweight and cross-platform version of the popular Entity Framework *". It is a lightweight, extensible, open source and cross-platform version of the popular Entity Framework data access technology. It can serve as an object-relational mapper (O/RM), enabling .NET developers to work with a database using .NET objects, and eliminating the need for most of the data-access code they usually need to write.
Sequelize and Entity Framework Core can be categorized as "Object Relational Mapper (ORM)" tools.
Sequelize and Entity Framework Core are both open source tools. It seems that Sequelize with 19.8K GitHub stars and 3.08K forks on GitHub has more adoption than Entity Framework Core with 8.01K GitHub stars and 2.05K GitHub forks.
WebbyLab, Hostr, and Decision6 are some of the popular companies that use Sequelize, whereas Entity Framework Core is used by Heimdal Security, InnoCellence, and accuRx. Sequelize has a broader approval, being mentioned in 53 company stacks & 182 developers stacks; compared to Entity Framework Core, which is listed in 3 company stacks and 13 developer stacks.
