VibeKit

A Next.js SaaS starter repo with auth, billing, teams, email, storage, admin and verification workflows built for coding agents to extend.

VibeKit: Early access, open to join. Get it at vibekit.dev.

VibeKit is a Next.js SaaS foundation designed for people who build products with coding agents such as Codex or Claude. Instead of an empty repo, the agent starts from a working application with authentication, billing across providers like Stripe, Polar and Paddle, teams and roles, email, storage, admin tools and documentation already in place. Agent workflow files such as AGENTS.md, PRODUCT.md and DESIGN.md guide the build, and local mocks for payments, email, storage and AI allow testing before connecting real services. Buyers get the full source code with one payment, unlimited projects including client work, and lifetime updates.
