libfx launches persistent adapter API. Vercel CEO Guillermo Rauch announced on October 17, 2026 that libfx's createFxAgent() now supports persistence, running locally or in the cloud via files, Postgres, or Vercel Workflows, and is compatible with Node.js and Bun. On Vercel, this capability leverages persistent workflows and queue infrastructure to deliver reliability with just 1 line of code; a process that crashes mid-tool-call can resume from the breakpoint. The capability will later expand to Pi, OpenCode, and custom harnesses. There are currently no further developments.
