  • Rails Erd

    Generate Entity-Relationship Diagrams for Rails applications

    This PR seems to fix it. But the issue is with the deprecating of “parent”. The PR has been open for a while, but they haven’t been able to fix the CI build.

  • RailRoady

    Ruby on Rails 3/4/5 model and controller UML class diagram generator. (`brew/port/apt-get install graphviz` before use!)

    Something that shows the relations' cardinality would be nice! Off-hand I do not know but there's this and maybe some other stuff here

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
