An AI framework built by the Gatsby team

About

• A framework for reliably running AI agents and workflows in production
• Development started in October 2024 and grew over about 15 months; hundreds of teams use the beta in production
• Used by real companies such as Replit, PayPal, and Sanity
• Ran reliably in large-scale production for months, so a 1.0 release is now considered possible
  • Reached a level of maturity where the API can be fixed
• New projects can be scaffolded with the 1.0 defaults through the CLI, and existing projects get automatic migration through a codemod
