    Scalability Roadmap

    Stage 10 – 1K users· Single EC2 + RDS

    Monolithic Node API + Next.js on a single EC2. PostgreSQL on RDS. Enough for launch and early traction.

    Stage 21K – 20K users· Load balancer + Redis + CDN

    Separate API and frontend servers. Redis for search caching. CloudFront CDN for images and static assets.

    Stage 320K – 200K users· ECS + Elasticsearch + Aurora

    Elasticsearch for product search. Aurora for high-read-throughput. ECS for API container scaling.

    Stage 4200K+ users· Microservices + Global infra

    Search, payments, and listings as separate services. Multi-region PostgreSQL. Dedicated fraud detection service.

    Cost Breakdown

    Development Cost

    $20,000 – $60,000 (12–24 weeks)

    Infrastructure Cost

    $300 – $3,000/month at scale (Stripe fees add 2.9% + $0.30 per transaction)

    Maintenance Cost

    $3,000 – $8,000/month for trust & safety, seller support, and feature development

    Security Considerations

    Stripe Connect identity verification for seller KYC
    Buyer-seller communication stays within platform to prevent off-platform fraud
    Automated fraud scoring on all transactions via Stripe Radar
    Review system with abuse detection to prevent fake reviews
    Chargeback management and dispute workflow built into admin panel
