Vercel introduces durable-harness for running coding-agent harnesses durably

Vercel announced durable-harness on X. In Vercel's words, it lets users run Pi, OpenCode, Codex, Claude Code, eve, fx or their own harness durably on Vercel, and agents automatically resume work after failures and run for hours, days or months.

A Vercel engineer, quoting the announcement, said the project builds on work on Workflow SDK, eve and fx and keeps the same open-source and portability semantics as Vercel's other projects. The announcement had about 1,000 likes on X by October 21. Vercel's announcement links to a blog post, "Making every harness durable". Pi's maintainers replied on X that they were excited to see Vercel building with Pi-Durable.
