Four coding agents, zero setup
Vercel Sandbox's new default image (vercel/sandbox/universal:latest) ships Node 24 and Python 3.14 with opencode, claude-code, codex and pi preinstalled on Ubuntu 26.04. Spin up an isolated agent sandbox with nothing to install — pin a SHA digest for reproducible runs, or ride `latest` for nightly security patches.
Bun.serve() WebSockets, deployed as-is
Set "bunVersion": "1.x" in vercel.json and your local Bun.serve() server — routes, fetch, and native WebSockets via server.upgrade() — deploys to Vercel Functions unwrapped. WebSockets run on Fluid compute's Active CPU pricing, so you pay only while messages process, not while a connection sits idle.
100+ connectors from your terminal
vercel connect create now completes setup for any of 100+ preset connectors straight from the CLI instead of clicking through the dashboard — easy to script into onboarding and CI.
Trace every Connect token
Vercel Connect adds observability: filter events, track metrics, and forward token-lifecycle data to any log drain endpoint — line-level visibility for debugging auth flows in production.
