Login, signup, reset, a gated shell, and a 3-step wizard.
Plans, usage meters, invoices. Wire Stripe where marked.
Members, roles, and an invite flow - multi-tenant basics.
Sidebar, workspace switcher, flash-free dark mode.

One install. No database, no keys, no setup - the whole app boots instantly.
Re-skin the product by editing two CSS variables; swap the mock data for your API.
Connect auth, billing, and the AI model behind marked seams, then deploy to Vercel.
"Keel saved us six weeks. The AI assistant, auth, and billing were just there - we shipped on day one."
"The cleanest starter I've used. The command bar and AI panel make it feel like a finished product."
"Re-skinned to our brand in an afternoon. Two variables and it looked fully custom."
"Onboarding, settings, team management - the boring 80% was done. We built the fun part."

It ships with a mock engine so it runs with zero keys. Going live is a one-function swap - point generateReply() at Claude via the Vercel AI SDK and the streaming UI is unchanged.
Marketing, pricing, full auth, onboarding, a gated app shell, dashboard, settings, billing, team management, and the AI surfaces - 12 routes, responsive in light and dark.
Edit two CSS variables to re-skin the whole product, then swap the typed mock-data layer for your API. Auth, billing, and AI sit behind documented seams.
Next.js 16 (App Router), React 19, Tailwind CSS v4, and strict TypeScript, with unit-tested session and billing logic.
