relivator is an open-source, MIT-licensed e-commerce starter template for Next.js 15 that combines better-auth, Polar payments, shadcn/ui, Tailwind CSS, and Drizzle ORM into a full-stack storefront foundation.
What is relivator?
relivator is a full-stack ecommerce template built on Next.js 15, React 19, and TypeScript 5.8. It takes a developer's environment variables and database connection, and produces a production-ready storefront with authentication, payment checkout, a customer billing dashboard, and database schema. The project is maintained by Nazar Kornienko (blefnk) as part of the Reliverse ecosystem and is available freely on GitHub.
Key Features
- Tech stack — Uses Next.js 15 with the App Router, React 19.1, TypeScript 5.8, Tailwind CSS 4.1, and shadcn/ui components.
- Authentication — Integrated with better-auth for signup, login, and session management, including automatic customer creation.
- Payments — Polar integration for checkout flows, subscription management, customer portal, and webhook handling, with sandbox or production environments.
- Database — Drizzle ORM with PostgreSQL on Neon (with Supabase planned); includes
bun db:push,bun db:auth, andbun db:studiocommands. - UI components — shadcn/ui components can be added or updated using the
bun uicommand. - Animations — Includes anime.js for animations.
- File storage — UploadThing integration for file uploads.
- Analytics — Vercel Analytics integration.
- DX tooling — ESLint, Biome, and Knip for linting, formatting, and dead-code detection.
- In-progress integrations — TanStack Form with ArkType validation, next-intl for i18n, Resend for email, and oRPC for API routes are marked as WIP.
Who is it for?
- Full-stack developers — who want a modern ecommerce foundation without building auth, payments, and a database layer from scratch.
- Startups and indie hackers — who need to ship a storefront with subscriptions and a billing dashboard quickly.
- AI-assisted development users — relivator 1.4.0+ is described as "AI-ready", optimized for AI-powered IDEs like Cursor to help beginners onboard.
- Next.js learners — who want to study a complete, type-safe implementation of auth, ORM, and payment flows.
What can you do with relivator?
- Launch a storefront — set up a product store with a landing page, pricing, and checkout through Polar.
- Manage subscriptions — after a user signs up, they can visit
/dashboard/billingto subscribe to plans and manage payments via the customer portal. - Extend with shadcn/ui — add or replace UI components with the
bun uiCLI instead of manually editing code. - Customize database — use
bun db:studioto inspect and edit the Drizzle schema visually.
How does relivator work?
The quick start is a five-command setup: clone the repository, install dependencies with bun, copy .env.example to .env, fill in environment variables (including Polar tokens), then run bun db:push and bun dev. The template reads the schema in src/app.ts (optional edit) and the auth config in src/lib/auth.ts, where you map your Polar product IDs to checkout slugs.
Alternatives
- versator — a sister template from the same author that replaces better-auth with Clerk and Polar with Stripe, and uses tRPC; its demo and docs are referenced from the relivator README.
