i won at the @ycombinator agents hackathon! 3rd place of the ai infra track 🏆 i built vercel for long-running agents. why: deploys often break week-long, human-in-the-loop runs. i wanted a safe, easy way to ship new versions without killing mid-run agents. what it does: one stable url. new workflow ids → to the latest build. workflow resumes → to the original build. pinned by image digest. and hotfix or migrate cohorts safely. demo below ⤵️
