diff --git a/Gems.txt b/Gems.txt
 Code quality:
 rubocop - linter
 https://github.com/prettier/plugin-ruby - (NOT A GEM!) Prettier for ruby
 overcommit - git hooks to run linting before commits, etc
 bundler-audit - check your gemfile for outdated gems with security issues
 bundler-leak - check your gemfile for gems with known memory leaks
 brakeman - rails static code analyzer with a focus on security
 sqlint - linter for SQL code (I know, not ruby, but useful for a lot of ruby apps)

 Background jobs:
 good_job - uses the DB as a queue just like delayed_job, but it's multithreaded :D
 delayed_job - Shopify's background processor. A bit slower than sidekiq, but doesn't need redis, is more robust, and adaptable to specific scenarios

 Database:
 sequel - Lightweight ORM
 dexter - auto indexer for postgres
 immigrant - check for missing foreign key constraints
 indexter - check for missing indexes on foreign keys
 rein - add extra constraints support to activerecord migrations
 database_consistency - find inconsistencies between model validations and database constraints
 database_validations - validations that use db constraints instead of just validating at the model level
 active_record_doctor - auto detect a bunch of issues in your models/db
 with_advisory_lock - use PG advisory locks from ruby. great as a cross-host semaphore!

 Pagination:
 pagy - full featured but performant and lightweight pagination (ORM-independent)

 Testing:
 database_cleaner - reset database state between tests
 fabrication - sane test factories
 formulaic - Simple form fililng for capybara tests
 ffaker - generate fake test data easily
 rack_test - test helpers for rack apps
 undercover - automatically find untested code in recent changes
 crystalball - run only the minimum necessary tests to cover your changes

 Monitoring:
 notable - log errors, timeouts, etc to the database and look at the data on an admin page
 ahoy_matey - opensource analytics. stores data in your own DB
 ahoy_email - ahoy for tracking emails
 app_perf (https://github.com/randy-girard/app_perf) - WIP on a new-relic-like APM platform

 Data analysis:
 blazer - easy BI dashboards for rails (good to query ahoy data p.ex)

 Authentication:
 doorkeeper - Oauth provider for ruby apps. https://github.com/doorkeeper-gem/doorkeeper

 Authorization:
 pundit - modular authorization library

 File uploads:
 shrine - flexible file upload handling for rack (doesn't depend on rails)

 Deployment:
 capistrano - the oldie but goodie
 tomo (https://tomo-deploy.com/) - like capistrano, but can also install ruby, node, set up puma systemd units, etc

 Misc:
 noticed (https://github.com/excid3/noticed) - multi-medium notifications for rails
 truemail - validate e-mail addresses by regex, DNS records, and actually checking on the SMTP server if the email exists
 phony / phony_rails - phone number validation
 autoload_reloader - autoloader with better behaviour than activesupport's autoloader
 runbook - progressive automation based on checklists
 ruby-prof - performance profiling
 test-prof - test profiling (great to find out why a test is slow)
 premailer-rails - easier CSS styling of action_mailer mails
 active_merchant - unified API to abstract payments using dozens of payment gateways
 alba (https://github.com/okuramasafumi/alba) - simple, small, and extremely fast serializer for ruby objects
 invoice_printer (https://github.com/strzibny/invoice_printer) - easy invoice PDF creator/generator
