Vibe Coding Stack 2026

The recipe

1. Spec before you vibe. One page: what it does, for whom, what it must never do. Paste it into every agent session. Vibes without a spec produce demo-ware.
2. Drive from Cursor (Pro $20/mo). Agent mode for scaffolding and feature work; keep a Sonnet-class model as default for cost control.
3. Heavy tasks to Claude Code (in Claude Pro $20/mo). Multi-file refactors, test suites and “make the build green” sessions run better in the terminal agent than in editor chat.
4. Model access via OpenRouter (~$10/mo). One key, every model: compare GPT-5, Claude and Gemini outputs on the same prompt instead of guessing which to trust.
5. Completions safety net: Copilot free tier. When Cursor’s monthly limits throttle you mid-month, Copilot’s free tier keeps tab completions alive.
6. Deploy to an edge host. Static front-end plus serverless endpoints (Vercel/Cloudflare free tiers). No servers, no Docker, no DevOps detour.
7. Git discipline from day one. Agents commit early and often — every prompt-sized change is a commit. git reset is the real undo button of vibe coding.
8. Test what you ship. Ask the agent to write the tests, then actually run them. Vibe-coded apps fail silently in ways only tests catch.

When this breaks down

The stack builds products faster than it builds understanding. The first production incident you can’t debug is the bill for skipped fundamentals — budget learning time or a contractor before that day.
