x is an open-source, full-stack React framework built natively on Bun. Instead of stitching together 5 separate tools, x handles SSR, file-based routing, API endpoints, server functions, auth, and image proxying in a single process. Key features: • Zero-config single Bun process architecture • Astro-style frontend speed + Next.js-style backend DX • Build-time secret isolation for server actions • Built-in @thexjs/mcp server so AI agents write valid code out of the box
