Theo vs Vercel — different layers of AI Cloud
Vercel optimizes the frontend layer of AI Cloud. Theo runs the agent itself — coding agent, scaffold, framework, and the backend deploy.
Vercel inspired part of Theo's DNA. This page is honest framing.
TL;DR
Pick Theo
Pick Theo if your product is agent-first — long-running workers, multi-language backends, agent runtime that survives caller disconnects.
You can use both: Vercel for the marketing frontend + TheoCloud for the agent backend.

When to pick Vercel
You're shipping a Next.js frontend
Vercel co-invented Next.js and runs it best.

Vercel's edge is mature; TheoCloud doesn't compete globally yet.
Marketing pages, dashboards, e-commerce
Vercel is the production-ready answer.
When to pick Theo
Your product is the agent
Actual agent that runs in CI, on cron, in backend workers.
You need backends in any language
Go + Python + Rust + Node in one monorepo, deployed together.
Long-running workloads
Vercel Fluid Compute is newer and narrower; Theo runs full containers by default.
Self-host matters

FAQ
Can I use both Vercel and Theo?
Yes, common pattern. Vercel for marketing site / Next.js frontend; TheoCloud for the agent backend.
Is Theo trying to replace Vercel?
No — Vercel won the frontend cloud category. Theo plays the agent backend role.
What does Vercel do better?
Frontend cloud at scale: Next.js native, edge functions, ISR, v0 prototyping loop, global edge network, preview deployments per PR.
Doesn't Vercel Fluid Compute handle long-running workloads?
Fluid Compute extends Vercel toward longer-lived workloads — it is newer and narrower than full container runtimes. For agent runtimes that hold state across many minutes and survive caller disconnects, a container platform (TheoCloud, or your own Kubernetes) is the more direct shape today.
