The Pulse: new trend of building “internal vibe-coding apps” at tech companies

The Pulse is a series covering events, insights, and trends within Big Tech and startups.

Today, we cover:

1. New trend: building internal vibe-coding apps at mid-sized companies. Ramp and Stripe built platforms for non-engineers to build internal websites and tools with, and both are taking off in those workplaces. I expect more companies to do the same.
2. Do us engineers really enjoy hard problems? Or do we actually like pattern-matching with backend problems? A provocative post by Cloudflare engineer, Sunil Pai, suggests there are other motives.
3. New open models launch in the EU and US. Kolibri, Mistral Large 4, and Beam by Reflection AI could challenge China’s dominance in open weight models.
4. Industry Pulse. Why Figma doesn’t let any agent use its MCP server; Google Cloud adds Swift support on the server side, Anthropic’s two-week sprint to speed up Claude Code, Coinbase dumps React Native shortly after Shopify announces doing so, Claude Opus 5.5 formats the C: drive, and more.
