Active Admin vs. PostgREST vs. pgweb

Active Admin is a Ruby on Rails framework for creating elegant backends for website administration.

PostgREST serves a fully RESTful API from any existing PostgreSQL database. It provides a cleaner, more standards-compliant, faster API than you are likely to write from scratch.

This is a web-based browser for PostgreSQL database server. Its written in Go and works on Mac OSX, Linux and Windows machines. Main idea behind using Go for the backend is to utilize language's ability for cross-compile source code for multiple platforms. This project is an attempt to create a very simple and portable application to work with PostgreSQL databases.
