Built by Rails developers, for Rails developers
A real head start for your next Rails SaaS
Each app kit is a set of real, designed screens for a kind of SaaS: dashboards, auth, settings, billing, and email, built in clean ERB and Tailwind. Start from the one closest to what you're building, then make it yours.
Rails-native code
Clean ERB templates and Tailwind classes wired to Stimulus and Hotwire. The product layer your AI-generated code is missing.
Coherent by design
Every screen in a kit agrees with the next. That's the system-level consistency AI can't generate one prompt at a time.
Yours to change, not a cage
Plain ERB and Tailwind you own the moment it's installed. Keep what fits, delete what doesn't, restyle anything. A head start, not a template you conform to.
App kits are not skins you drop over an app. They are the screens a real product needs, already designed and wired for Rails: full pages, layouts, and the patterns that connect them. Pick the kit closest to your idea, keep what fits, change what doesn't, and ship months sooner.
