## What it is
Catarse is an open-source crowdfunding platform for creative projects, originally built in Brazil and running catarse.me. It is a Ruby on Rails application with a PostgreSQL database and a PostgREST-based API using JWT authentication.

## Use cases
- launch a crowdfunding platform for creative projects

## When to choose

## When to avoid
- you need active maintenance or recent security updates - the repo is deprecated
- you are not comfortable with legacy Rails 4.2 and Ruby 2.4
- you need a modern stack or official support - development moved to common-group/services-core
