Amazing tool.

Works like magic, and easy to set-up. I've used this to transcribe long podcasts and make them searchable.

Unified and simple API to get video information and stats from different platforms (YouTube, Vimeo, and more) via official APIs, with fallback to web scraping if you don't have the API keys.

While it is probably the most customizable and flexible gem for file uploads, it might be too complex. I personally prefer to use a paperclip, carrierwave, or activestorage when I need to have just a simple file upload.

Rubocop is probably the de facto linter and static code analyzer for Ruby. It comes with some "sensible" defaults, but it's really really flexible, so your team can easily customize your preferences. The hardest part is to align those preferences :) That's why probably Standard Ruby exists.

Very useful gem to run distributed "cron" tasks over Redis. It works with minimal setup, you just need to define a YAML with your tasks and their scheduling time (that can be defined in natural language: "every 6 hours").
