For the code you already have
App builders are great for a new prototype. KLINCH is for the next hundred changes to a real repository.
Start from your repository
Connect any existing GitHub repository and branch: a Next.js site, a backend, a library. The agent learns the structure from the code itself instead of generating a project from a template.
Your hosting stays the same
KLINCH only writes commits. Cloudflare, Vercel, Netlify or your own CI keep deploying the repository as before, so there is nothing to migrate.
Your model, your bill
Instead of credits, KLINCH uses your provider key, so heavy weeks cost what the tokens cost.
