Guillermo Rauch says createFxAgent() in libfx now runs durably on a laptop or in the cloud, using files, Postgres, or Vercel Workflows.

Rauch says libfx adds a durability adapter API for this, and that on Vercel it uses the infrastructure built for durable workflows and queues, giving reliability with one line of code. He says the same durability will come to Pi, OpenCode, and custom harnesses. The report is a post on X and does not include independent testing.

    Vercel's fx.sh makes agent sessions durable across crashes and restarts

    AIGuillermo Rauch says createFxAgent() now runs durably on a laptop or in the cloud via files, Postgres, or Vercel Workflows in Node.js or Bun. The libfx durability adapter API keeps a turn running to completion after a user disconnects and resumes a crashed tool call from where it stopped, with one line of code on Vercel. Rauch says the same durability will come to Pi, OpenCode, and custom harnesses.
