About Seedep.
How is this different from a plain chatbot starter?
Besides chat, you get a credits wallet, subscriptions, permissions, and admin. The agent layer is pluggable — swap instructions and tools to become your vertical product.
Can I try it without an LLM API key?
Yes. Without LLM_API_KEY the demo agent runs offline, still spending credits and streaming SSE so you can validate the product loop.
How do I add my own agent?
Copy libs/agent/agents/demo, change instructions and tools, register it. Auth, billing, and admin stay untouched.
How do credits and subscriptions work?
Each agent run spends credits first. Stripe Checkout plus webhooks grant subscription credits. WeChat and Alipay stubs live under libs/payment.
What is the stack?
Nuxt, Better-Auth, Drizzle/PostgreSQL, AI SDK, Tailwind, and a shared design system.

Start with a chat, prove the runtime, then grow it into your SaaS.
