Vercel Edge + Serverless

StackSwap runs on Vercel with a mix of Edge and Node serverless functions. Lightweight API routes (email capture, waitlist, analytics events) run at the edge for low latency; StackScan's heavier work (LLM calls, Supabase writes, Stripe verification) runs on Node. Background scan jobs are claimed via a Supabase RPC and executed in Node functions with retry/reclaim logic so a slow or failed job never blocks the intake flow.

Preview deploys run on every PR, so any change to the StackScan pipeline, pricing UI, or data layer is reviewed in a production-like environment before merge. The same Vercel project hosts marketing, product, and the internal dashboard — one deploy, one rollback, one set of env vars.

Edge + Node under one Vercel project lets StackSwap ship fast without running its own infrastructure. Cron + job-claim patterns turn long-running work into something the UI can fire-and-forget and the report page can poll — the user sees 'analyzing…' and the backend handles the rest.
