Changes to Tech stack

Oct 10, 2025

After some research I decided to trade scalability for cost since I'm starting small

Here's the changed tech stack

💻 Tech Stack

DomainTechnologyRole
FrontendNext.jsFrontend will still be developed in Next.js
Hosting & CDNVercelFor faster development I decided to use Vercel instead of AWS to deploy frontend
Database & Vector SearchSupabase (PotgreSQL)I will use pgvector for Rag and Supabase Storage for storage
AU OrchestrationAWS Lambda(Python)I will still stick with Lambda for RAG and do the heavy computation and this will be a learning opportunity
AuthenticationSupabase AuthUser management, JWT and I was more familiar with this than Cognito anyway
Billing/FinOpsStripe API (Webhooks)I will use Stripe for Payment
GenAIGeminiI will use Nano Bannana for image generation

TL&DR

Did my research and changed my tech stack to vercel + supabase + aws lambda
