Ruby / Rails is a first-class citizen for most AI tools due to convention-heavy codebases.

FAQ
Is Cursor the best AI tool for Ruby?
Depends on your workflow. Cursor is strongest when you want autocomplete speed. For a full head-to-head, see the comparisons page.
Does Cursor support the latest Ruby version?
Cursor supports models like claude-sonnet-4-6 and claude-opus-4-7, which are trained on Ruby through late 2025 at minimum. Bleeding-edge language features may need context.
Can I use Cursor offline for Ruby?
Yes, Cursor supports local models via Ollama or LM Studio, which works for Ruby but with smaller model quality.
