What Is Codapult
Codapult is a production-ready SaaS boilerplate for Next.js 16. It gives you 70+ removable modules — authentication, billing, teams, AI chat, admin panel, blog, help center, and more — so you can ship a SaaS product in days instead of months.
Every module is self-contained and independently removable. Run the interactive setup wizard (npx @codapult/cli setup) to strip out what you don't need, and you're left with a clean codebase tailored to your product.
Key Differentiators
Adapter Pattern
Auth, payments, storage, background jobs, and notification transports all use a unified adapter interface. Switch providers by changing a single environment variable — no code changes:
| Adapter | Providers | Env Var |
|---|---|---|
| Auth | Better-Auth (default), Kinde, None | AUTH_PROVIDER |
| Payments | Stripe (default), LemonSqueezy | PAYMENT_PROVIDER |
| Storage | Local (default), S3, R2 | STORAGE_PROVIDER |
| Background Jobs | In-memory (default), BullMQ (Redis) | JOB_PROVIDER |
| Notifications | Poll (default), SSE, WebSocket | NOTIFICATION_TRANSPORT |
| Embeddings | OpenAI (default), Ollama | EMBEDDING_PROVIDER |
| Vector Store | SQLite (default), In-memory | VECTOR_STORE_PROVIDER |
