Pylon Sync emerges as an agent-first, full-stack, real-time framework designed to streamline the development and deployment of applications, bridging the gap between hobby projects and production-ready systems. It integrates server-rendered React, TypeScript functions, entities, and policies, offering real-time synchronization, built-in authentication, and job management capabilities. The framework defaults to SQLite but supports PostgreSQL for production environments, with an authentication system inspired by better-auth.

The runtime is powered by a Rust server executing TypeScript functions and server-rendered React via Bun. Pylon emphasizes convention over configuration, drawing parallels with Rails. Its architecture aims to simplify app development for coding agents by providing a cohesive system that includes schema management, access policies, and typed React clients, eliminating the need for separate resolvers or backend services. All backend components—schema, sync, auth, functions, storage, and SSR—share a single schema and runtime.

Pylon facilitates easy self-hosting as a single binary or offers Pylon Cloud for managed hosting, providing a developer experience akin to Vercel. Deployment is achievable via Git integration or its CLI, with apps running on scalable, zero-idle servers. The managed hosting includes features like global caching and TLS. Pricing tiers range from a free Hobby plan to a Pro plan at $25 per organization per month, with custom Enterprise options available.
