What’s in this stack
Query and interact with PostgreSQL databases, inspect schemas, and run SQL directly from your AI editor.
Rails convention is Postgres in production. Query your database, inspect Active Record schemas, and debug migrations inline.
Manage Docker containers, images, volumes, and networks. Run, stop, inspect, and monitor containers from your AI editor.
Containerize your Rails app with all its dependencies — Redis, Postgres, Sidekiq — in one Docker Compose stack.
Pull up-to-date documentation and code examples for any library directly into your prompt context using the Context7 API.
Rails has strong conventions that change between versions. Up-to-date docs prevent your AI from generating Rails 6 patterns in a Rails 7 app.
Access the GitHub API to manage repositories, issues, pull requests, branches, and workflows directly from your AI editor.
Rails PRs tend to be large and convention-heavy. GitHub integration makes code review and CI management seamless.
Automate browser interactions, take screenshots, fill forms, and test web applications using Microsoft Playwright from your AI editor.
Rails system tests pair perfectly with Playwright. Test your full-stack Rails app from browser to database in one flow.
