Popular “Vibe-Coding” AI Stacks
| # | Stack Nickname | Core Components (Hosting / DB / Auth / LLM & Vector) |
Key Advantages | Typical Use Cases |
|---|---|---|---|---|
| 1 | VANS-AI (Vercel + Auth.js + Next.js 14 App Router + Supabase Vector) |
• Vercel Edge Functions • Supabase (Postgres + Realtime + Vector) • Auth.js or Clerk • OpenAI Assistants / Function Calling |
“Zero-ops” serverless workflow; full-stack TypeScript; huge mind-share in VC & SaaS circles | Landing-page → SaaS MVPs (e.g., FundWise AI) |
| 2 | CF-Edge AI | • Cloudflare Workers / Pages • D1 (Edge SQLite) + KV • Hono or SolidStart Router • Cloudflare AI Gateway or OpenAI • Auth.js |
Ultra-low latency from 100+ POPs; no cold starts; built-in WAF & R2 object store | Globally distributed user bases, docs/API startups |
| 3 | AWS Bedrock Serverless | • API Gateway + Lambda • DynamoDB + Bedrock vector store • Cognito / IAM • Amazon Bedrock (Claude 3, Llama 3, Titan…) |
Single-cloud governance, widest compliance set (HIPAA, SOC 2); swap models inside AWS | Fin-/Med-tech, strict regulatory environments |
| 4 | Fly-Neon-Qdrant | • Fly.io Machines (Edge Postgres proxy) • Neon Serverless Postgres (branching) • Qdrant or Weaviate (vector) • Bun/Node or Go • Clerk |
Cost-friendly; easy multi-region (EU ↔ US); Neon’s zero-copy branches = fast preview envs | Dev-heavy teams, many staging/preview pipelines |
| 5 | Replit Deploy + LangChain | • Replit Deploy Edge Containers • Supabase / PlanetScale • Replit Auth & Secrets • LangChain + OpenAI / Anthropic • Upstash Redis for rate-limits |
Cloud IDE + instant deploy; Ghostwriter AI pair-programming; perfect for solo hackers | Hackathons, weekend tools, teaching & live demos |
Why These Five Lead the Conversation
- VANS-AI is dubbed the “SaaS assembly line” in the Vercel community—tons of starter kits and blog tutorials make it the default for early-stage founders.
- Cloudflare Workers plus the new D1 edge database sparked the “Edge-first” movement; tech blogs keep highlighting sub-50 ms global latencies.
- AWS Bedrock lets enterprises stay within one cloud while switching between Claude, Llama 3, Titan, etc., balancing compliance and flexibility.
- Supabase’s native Vector store (released 2025) powers both VANS and Fly-Neon stacks, cutting integration time for RAG pipelines.
- Replit’s “100 % AI-generated code” demos went viral; the in-browser IDE + one-click deploy drastically shortens MVP cycles.
All five stacks allow plug-and-play swaps (e.g., Clerk ↔ Auth0, Qdrant ↔ Pinecone). Choose based on compliance needs, team skillset, and target user geography.
