Absolutely! Rails continues to power incredibly productive teams and large-scale apps (GitHub, Shopify, Airbnb, Stripe, etc.). Rails uniquely enables small teams—or even solo developers—to build powerful, integrated apps quickly, which is exactly the environment I want for an AI agent.

Rails’ structure (ActiveRecord, migrations, generators, rich conventions) provides a deeply introspectable, consistent, and predictable environment—perfect for autonomous AI agents to learn, understand, and reliably execute tasks.

Other frameworks often require more custom glue or boilerplate. Rails is "batteries-included," which lets an AI agent leverage existing integrations (like Twilio, Gmail, Stripe, Quickbooks, etc.) out-of-the-box, making it the ideal playground for experimenting with powerful, generalized agents.

I built my first startup on Rails, it's extremely powerful and productive for solo devs, and my tool of choice for building quickly. :)
