# RubyCoder.ai vs TrendingDevTools

> RubyCoder.ai is the better fit for Ruby and Rails developers who want gems, libraries and tutorials for LLMs, agents or RAG. TrendingDevTools suits developers and founders who want to browse trending tools across many languages, or makers who want a free listing for a developer product.

RubyCoder.ai and TrendingDevTools are both free directories, but they cover different ground. RubyCoder.ai focuses on Ruby. It lists 3,292 resources for AI and machine learning, including 762 gems, 98 frameworks and over 2,000 articles.

TrendingDevTools is broader. It lists more than 77 developer tools, AI tools and SaaS products, such as Supabase, Firecrawl and Svix, each with a pricing tag. Makers can submit a tool for free or pay for a sponsored spotlight.
