Vibe Coding's $4.7B Quarter: What 92% Developer Adoption of AI Codegen Means for Who Owns the Deploy Target
Vibe-coding tools hit $4.7 billion in 2026 spend with 92% daily developer adoption, but every one of those dollars pays for the tool that writes the app, not the platform that runs it. Here's the deploy-target map — which vendors bundle deployment, which stay open to any agent — and what that split actually costs once a prototype becomes a real production app.
9 Seconds to Delete Production: What 93% of AI Agent Incidents Teach About Deploy-From-Chat Guardrails
A 9-second database deletion, a 13-hour AWS outage, and a blown annual budget — five documented 2026 AI agent incidents, the common root cause behind all of them, and the specific guardrails that would have stopped each one.

OpenWorkers and Vorker let you run Cloudflare Workers' V8-isolate model on your own hardware. Here's the real cold-start, memory, and filesystem tradeoff against a container-based PaaS, with numbers.
