Massive vs Postico: What are the differences?
What is Massive? A Postgres-Centric Data Access Tool. Massive's goal is to help you get data from your database. This is not an ORM, it's a bit more than a query tool - our goal is to do just enough, then get out of your way. Massive embraces SQL completely, and helps you out when you don't feel like writing another mundane select * from statement.
What is Postico? A modern PostgreSQL client for OS X. Postico provides an easy to use interface, making Postgres more accessible for newcomers and specialists alike. Postico will look familiar to anyone who has used a Mac before. Just connect to a database and begin working with tables and views. Start with the basics and learn about advanced features of PostgreSQL as you go along.
Massive and Postico can be primarily classified as "Database" tools.
