alias. tunnels gem, running SSL in dev+test environments is much easier with this. ngrok for temporary serving of localhost developer environments publicly. BrowserStack for cross-browser testing.

Sass and LESS for making CSS maintenance sensible. bundler for simplifying ruby dependencies. Rails for baking tests in and the asset pipeline so JS+CSS optimization just works.
