#  A Vercel alternative for one-off agent artifacts.

   Vercel is built for products — projects, branches, previews, environments. For the case where an agent emits one HTML file and you need a private link in 200 ms, that's the wrong granularity. Stacktree is the right granularity.

##  What is a Vercel alternative for agent-emitted HTML?

Stacktree. Vercel is a deployment platform; Stacktree is a publish primitive. Both can host static HTML, but Stacktree skips Vercel's project/branch/preview model in favour of a single MCP tool call. Each agent-emitted artifact gets an unguessable URL in ~200 ms — private by default, gated by password or email domain, and replaceable in place across iterations.

## Where Vercel is great (and Stacktree shouldn't try to compete)

  - Production hosting for a Next.js / SvelteKit / Astro app with edge functions, serverless routes, and ISR.
 - Branch previews tied to Git, where every PR gets its own URL.
 - Teams managing a small number of long-lived projects with CI integrations.

## Where Vercel is heavy

The granularity mismatch hurts the moment your agent starts emitting one-off HTML several times an hour:

  - Project overhead. Every artifact wants its own project, or it shares one and gets a deploy URL nobody can keep track of.
 - Build pipeline. Even a "static" deploy goes through the build pipeline, which takes 10–60 s.
 - Public by default. Preview URLs are public unless you enable Vercel Authentication (paid, organisation-wide).
 - No replace-in-place semantics for non-production. Each agent iteration generates a new preview URL.

## What Stacktree does instead

  - One tool call. The agent calls publish_html; Stacktree mints a URL.
 - Private by default. The URL is unguessable; optional password and email-domain gates layer on top.
 - ~200 ms latency. No build, no DNS, no certificate dance.
 - Replace-in-place. Every revision swaps the content under the same URL.
 - Custom domain from Solo, $19/mo. Via Cloudflare for SaaS. DNS-only, we handle TLS.

## When to use both

 Your product lives on Vercel. Your agent's one-off outputs live on Stacktree. The two don't overlap once you draw the granularity line at "is this an artifact or an app?" Artifacts on Stacktree, apps on Vercel.

FAQ

## Frequent questions

     What about Vercel Drop (June 2026)? +  Vercel Drop deploys a dragged file or folder with no Git or CLI — the easiest on-ramp Vercel has shipped, and great when the artifact is an app. Its documented limits are the agent-shaped gaps: it requires a Vercel account, publishes straight to a public production URL with no privacy controls in the flow, and per Vercel's docs "doesn't redeploy into an existing project," so every iteration is a new project and URL. Full breakdown: [stacktr.ee/blog/what-is-vercel-drop](/blog/what-is-vercel-drop).   Is Stacktree a Vercel competitor? +  Not for product hosting. Vercel is excellent for that. Stacktree competes with Vercel only for the narrow shape of "an agent emitted one HTML file and I want a private link" — a job Vercel can technically do, but with disproportionate setup overhead per artifact.   Why not just deploy each artifact to Vercel? +  Three frictions. (1) Each artifact wants its own project or deploy slot. (2) Vercel's preview URLs are public unless you wire Vercel Authentication (paid). (3) Deploys take 10-60 seconds; agent loops fire faster than that. Stacktree publishes in ~200 ms with a private URL by default.   Can Vercel's preview URLs do replace-in-place? +  Production aliases can, but each agent-emitted artifact would need its own production alias. Stacktree treats `update_site` as a first-class verb: one URL per artifact, every revision swaps the content under it.   What about Vercel's edge functions and serverless? +  Out of scope for Stacktree — we host static HTML only. If your agent is generating dynamic apps with a backend, deploy them to Vercel. If it's generating self-contained HTML files (most agent output), Stacktree is the lighter primitive.   Does Stacktree run on Vercel? +  No — Stacktree runs on Cloudflare Workers, R2, and D1. Edge-first by design.
