Superset, an IDE for parallel AI agent development, runs on Vercel and handles 1,000–1,400 deployments per week with ~30 second average build time

Superset is built by three former YC company CTOs (Kiet Ho, Satya Patel, Avi Peltz) as an IDE that lets developers run up to 10 coding agents in parallel, each in its own isolated workspace, generating code across multiple branches simultaneously.

The platform runs six Next.js projects on Vercel (web app, marketing site, docs, and three supporting services) and generates roughly 600 preview deployments per day internally. Every branch automatically gets a live preview URL without deploy queue delays, powered by Vercel Blob for artifact storage, Cron Jobs to manage environments, and AI Gateway for model routing.

Superset experienced 57–64% week-over-week DAU growth and absorbed a Hacker News spike where user counts tripled overnight without manual infrastructure provisioning. The team reports customer incident fixes can spin up, preview, and merge in under thirty minutes with near-zero rollback cost.
