What is ruby-companies?

Ruby Companies is a community-maintained directory of companies that build software using Ruby. Think of it as a public, searchable list where developers can find employers who work with the language, and where businesses can showcase their tech stacks to attract talent. The project powers a website where each company gets a profile. You can see details like where the company is headquartered, what technologies they use, and whether they offer remote, hybrid, or on-site work. The list is organized by location, continent, country, region, and city, so you can browse by geography or just scroll the overview to spot interesting companies and their main tools. It also tracks when a company was added, so you can see which ones are newest to the list. Anyone in the Ruby community can add or update a company. You do this by submitting a pull request with a simple text file containing the company's details, like its name, location, website, and tech stack. The maintainers are especially encouraging about adding smaller companies, not just big names. Behind the scenes, the website is built with Bridgetown, a modern tool for generating static websites using Ruby, but contributors only need to fill out a straightforward template to participate. The project is useful for Ruby developers looking for their next job, since it provides a curated view of potential employers and their work arrangements. It is also handy for founders or contractors who want to see which companies are invested in the Ruby ecosystem in a particular region. The tech stack listings, which highlight a company's main language, database, and frontend framework, give a quick sense of what working there might look like.
