    Also this doesn't show how database access is handled which is the hard part. If you are not touching the database, you can run Rails on falcon and get fiber based concurrency.

    If you run falcon on rails and access database, then you have to explicitly checkin/checkout a connection to be safe. Details here -

  • Spree Commerce

    Project mention: Ask HN: Suggestions about platform to develop a customizable B2B marketplace | | 2023-05-01
  • ActiveAdmin

    The administration framework for Ruby on Rails applications.

    Project mention: Ask HN: Why aren't Django Admin style dashboards popular in other frameworks? | | 2023-10-28

    Can you clarify what's the "tremendous value" you're getting out of the Django admin?

    At Heii On-Call we are using Active Admin for Ruby on Rails, which seems quite similar to the Django admin. In my experience, it's mostly useful as a fairly basic read-only view of what's in the database. In Rails, it's so easy to whip together a custom view that we tend to do that, and the Active Admin is nice to have but I wouldn't say "tremendous value".

  • Kaminari

    ⚡ A Scope & Engine based, clean, powerful, customizable and sophisticated paginator for Ruby webapps

    Project mention: 12 Ruby Gems to make your Ruby coding smoother | | 2023-08-22

    With around 50 new gems released daily, it is common to use trending libraries for managing everyday tasks. You probably use Devise for authentication, Cancan for authorization, Kaminari for pagination, or run tests with Rspec.

  • Simple Form

    Forms made easy for Rails! It's tied to a simple DSL, with no opinion on markup.

    Project mention: Internationalize and Humanize your Ruby on Rails application | | 2023-08-23

    I also tend to use gems like simple_form to generate my form HTML, and this saves me from having to maintain a lot of view code to outputting translated content onto forms. Also simple_form has it's own i18n convention that compliments the Rails default pretty well.

  • factory_bot

    A library for setting up Ruby objects as test data.

    Project mention: Metaprogramming in Ruby: Advanced Level | | 2023-06-30

    factory_bot: A fixtures replacement

  • Brakeman

    A static analysis security vulnerability scanner for Ruby on Rails applications

    Project mention: [Tool] An alternative to Brakeman for Security | /r/rails | 2023-07-11

    My team and I released Bearer a couple of weeks ago, a newer open and free alternative to Brakeman to check your code for security and privacy risks. In addition to Ruby/Rails, we also cover your JS/TS code, which allows you to use a single solution for your whole Rails application.

  • PaperTrail

    Track changes to your rails models

    Project mention: historical data and "point in time" data modeling techniques, advice. | /r/dataengineering | 2023-06-28

    if the source (web) application makes their own audit tables. ex: our ruby on rails application uses the paper-trail gem

  • Searchkick

    Intelligent search made easy

    Project mention: Most performant way to build an analytics dashboard from a relational database backend that only stores numeric values, where the data the end-user sees is "categorized" into numeric brackets (e.g. 60-79 = Med, 80-100 = High, etc) | /r/rails | 2022-12-11

    I run a large scale production application that does something along these lines. If the data needs to be close to real-time, I'd say use `searchkick` + Elasticsearch, and use `searchkick`'s async feature to "stream" the data from your table to the ES index. Your dashboard will then just query from the ES index via searchkick.

  • MailCatcher

    Catches mail and serves it through a dream.

    Project mention: Preview emails with letter_opener, MailCatcher and MailHog | | 2023-08-13

    hey HN, I recently published an article going deep into email previewing (in Ruby on Rails, but I think it's relevant beyond Rails).

    MailCatcher ( and MailHog ( are super handy and easy to run locally. Both spin up an SMTP server which you can direct mail to, and give you a nice web interface to browse mail and preview it.

    Happy to answer any question! thanks, harrison

  • FriendlyId

    FriendlyId is the “Swiss Army bulldozer” of slugging and permalink plugins for ActiveRecord. It allows you to create pretty URL’s and work with human-friendly strings as if they were numeric ids for ActiveRecord models.

    Project mention: Sqids – Generate Short Unique IDs from Numbers | | 2023-11-25

    On a side note, "Sqids ... is an open-source library that lets you generate YouTube-looking IDs from numbers.", "The main use of Sqids is purely visual."

    If the purpose of it is to give a friendlier url / id, who not use something like friendly_id instead? (

    The url is readable and searchable through the history.

    I would much rather prefer people using "" instead of "".

  • Administrate

    A Rails engine that helps you put together a super-flexible admin dashboard.

  • will_paginate

    Pagination library for Rails and other Ruby applications

  • ransack

    Object-based searching.

  • CanCanCan

    The authorization Gem for Ruby on Rails.

    Project mention: A guide to Auth & Access Control in web apps 🔐 | | 2023-11-07 (Ruby on Rails ABAC) Same like casl.js, but for Ruby on Rails! Casl.js was actually inspired and modeled by cancancan.

  • Webpacker

    Use Webpack to manage app-like JavaScript modules in Rails

    Project mention: Asset Pipeline JS Migration | | 2023-02-01

    Using Webpacker in Rails provides several advantages over the traditional asset pipeline. First, Webpacker uses JavaScript modules, which allows for better code organization and improved code reusability. Second, it offers modern frontend build tools, such as Babel and PostCSS, for transforming and compiling assets. Third, it provides faster build times and faster runtime performance through code splitting and lazy loading. Fourth, it offers better integration with JavaScript frameworks such as React, Vue, and Angular. Overall, Webpacker offers a more flexible and modern asset management solution for Rails applications. And while Webpacker is being retired, this initiative is to consolidate our code accordingly before moving our bundler to another solution.

  • graphql

    Ruby implementation of GraphQL

    Project mention: Rails 7.1 Released | | 2023-10-05

    My memory is fuzzy, but...

    1. all data flow through the rails app (no pre-signed s3 upload or download links for direct uploading).

    2. no support for CDNs (I think newer rails versions added support)

    3. blobs and attachments were unnecessary abstractions.

    3a. Querying was annoying and easy to add n+1 queries.

    3b. Images are moderated and it was unclear where to put the moderation metadata (on blobs? attachments? create a new table? why so many tables?). Accessing the data was annoying (you need extra joins).

    4. GraphQL gem didn't support it:
