Modern tech stack

What a modern tech stack looks like for AI-era products — and how to choose one that won't trap you.

What a modern stack means in practice

A modern tech stack is not the newest thing — it is the right combination of tools that let a small team ship fast, scale without rewrites, and hand the system to a larger team later without pain.

For most founder-led and growth-stage products in 2025–2026, that means: a React-based full-stack framework (TanStack Start or Next.js), a managed Postgres backend (Supabase), edge compute (Cloudflare Workers or Vercel Edge), and an AI-assisted build tool (Lovable or similar) for accelerating the front end.

The core decisions

  • Framework: TanStack Start (Cloudflare-native, type-safe routing) vs. Next.js (larger ecosystem, Vercel-native)
  • Database: Supabase (Postgres + auth + edge functions) vs. PlanetScale / Neon / raw RDS
  • Deploy target: Cloudflare Workers (global edge, low latency) vs. Vercel / Fly.io
  • AI build layer: Lovable (full-stack generation) vs. Cursor (code-level) vs. v0 (UI-only)
  • Payments: Stripe (standard) — managed by Lovable Cloud when applicable

What B. works with

B. PM Consulting builds on TanStack Start, Supabase, Cloudflare Workers, and Lovable for most client-facing products. This stack is what powers bpagelsminor.com, CanonIQ, FounderIQ, and the broader BPM product suite.

What to avoid

  • Over-engineering before product-market fit — keep the stack boring until you need more
  • Choosing a stack based on familiarity rather than operational fit
  • Ignoring edge compute costs at scale
  • Building auth from scratch when Supabase Auth or Clerk exist
