Stainless

Stainless positioning themselves as "fittings for your REST API" is the kind of nerdy wordplay that makes developers actually smile — they're calling themselves the connectors, the adapters, the little bits that make the whole system hold together. That's a strong bit of branding for a dev tool, and honestly, with just the tagline and a gallery listing, it's early days still — but the name alone tells you exactly who they want to appeal to.
