4. We need RSS for sharing abundant vibe-coded apps
We need RSS for sharing abundant vibe-coded apps — simonwillison.net · 19h ago · ⭐ 19/30 The article argues for the necessity of RSS feeds to facilitate the sharing of abundant “vibe-coded apps,” which are increasingly personal, situated, and frequent micro-applications. Matt Webb proposes an RSS web feed for these tools and app pages, each featuring an “Install” button, despite acknowledging the challenge of where these apps would be installed. This need arises because “vibe-coding” accelerates app development, making traditional, large-scale app launches less relevant for these smaller, more numerous tools. The core idea is to create a syndication layer for a new paradigm of rapid, personalized app creation. This approach would allow users to discover and integrate micro-apps more fluidly into their workflows. 🏷️ RSS, app distribution, vibe-coded apps, discovery —
