Ruby on Rails Guide Best Hosting for Rails (2026)
Compare the best hosting platforms for Rails. We review Railway, Render, Fly.io, Kamal, and more with deployment patterns.
Rails deployment has evolved from Heroku to modern platforms and Docker-based deploys with Kamal. We've evaluated hosting options for Rails apps of all sizes.
Pourquoi C'est Important
Rails needs a Ruby runtime, asset pipeline support, and often Sidekiq workers. The right platform handles all this with minimal configuration.
Considérations Clés
Kamal vs PaaS
Kamal (formerly MRSK) lets you deploy Rails to any server with Docker. PaaS like Railway handles infrastructure for you.
Asset Pipeline
Rails 7+ uses Propshaft/import maps. Older apps need Node for Webpacker. Ensure your platform supports your asset strategy.
Background Jobs
Most Rails apps use Sidekiq. You need Redis and a way to run worker processes alongside the web process.
Database Access
Rails console and migrations need database access. Ensure your platform supports rails db:migrate in deploys.
Action Cable
For WebSockets with Action Cable, you need sticky sessions or Redis adapter. Not all platforms handle this well.
