Pylon

Full-stack framework for coding agents that combines a TypeScript model with schema, policies, server functions, and typed clients for live sync, auth, storage, and one-binary deploy.

What is Pylon?

Pylon is a full-stack framework designed for coding agents, allowing developers to define a single TypeScript model that automatically generates schema, REST and realtime APIs, row-level security, and a typed React client. It integrates backend components like sync, auth, storage, server functions, jobs, and search into one deployable binary, supporting SQLite or Postgres.

How to use Pylon?

  1. 1Create a Pylon project and connect a GitHub repository.
  2. 2Define your app model in TypeScript (entities and access policies).
  3. 3Push code to the default branch; Pylon automatically deploys and syncs the schema.
  4. 4Alternatively, use the CLI: run `pylon login`, then `pylon deploy --target cloud`.
  5. 5Manage scaling and settings from the Pylon Cloud dashboard.
