The complete 2026 OpenCode guide: what it is, how to install it, AGENTS.md, what it costs, and when to pick Claude Code or Codex.
A 5-phase professional flow for taking vibe coding to production in Next.js: cuts per tool, the Cursor-plus-v0 combo, review before deploy, spending caps, and a planned exit.
AI-generated auth passes the demo and breaks in production: colliding sessions, 3 middleware patterns, 20M tokens in one bug, and $15k debug versus $6k build, with an off-prompt checklist.
What vibe coding costs in credits and tokens with Replit, Bolt, Lovable, and v0 numbers, where the doom loop multiplies 5.4x, and how to lock the bill.
