Astro on Vercel
Vercel publishes its own guide for deploying Astro.
Content-focused framework that ships zero JavaScript by default and renders components from several UI libraries.
What Astro needs.
Every host claims to run Astro, so the claim on its own decides nothing. These are the things Astro actually requires from the platform underneath it, and what Vercel publishes about each. Vercel documents 4 of the 4.
Build allowance
No monthly build-minute allowance. Build CPU minutes are billed from $0.0035 each on Pro, against the plan's usage credit, and any single build is capped at 45 minutes.
Astro prerenders by default, so most of the work happens at build time and the build allowance is the real constraint.

- Limits — Vercel docs ↗
“Build Time per Deployment (Minutes) 45 45 45 [...] Build CPU Minutes Starting at $0.0035 per CPU Minute [...] The maximum duration of the Build Step is 45 minutes. When the limit is reached, the Build Step will be interrupted and the Deployment will fail.”

Concurrent builds
Pro: up to 500 concurrent deployments with on-demand concurrency, or 3 if on-demand concurrency is off
A content site rebuilds on every edit. One build slot turns a busy publishing day into a queue.

- Managing builds — Vercel Docs ↗
“Concurrency limits by plan Hobby: 1 concurrent deployment. Builds beyond this run sequentially. Pro: Up to 500 concurrent deployments with on-demand concurrency (3 if on demand is off). You are billed for the build minutes you use. Enterprise: Custom concurrency limits tailored to your organization's needs.”

Edge network
Supported
A prerendered Astro site is a directory of static files. After that, the only thing left that affects speed is where they are served from.

Git deployment
Supported
Astro's usual workflow is a push that triggers a build. Anything else means wiring the build yourself.

Astro features on Vercel
Capabilities Vercel documents specifically for Astro, with the constraint it documents alongside each.
ssr_adapter
Supported
Using SSR, or on-demand rendering as Astro calls it, enables you to deploy your routes as Vercel functions on Vercel. This allows you to add dynamic elements to your app, such as user logins and personalized content. [...] Or, manually installing the @astrojs/vercel package
Image optimization
Supported
When deploying to Vercel, images are automatically optimized on demand, keeping your build times fast while improving your page load performance and Core Web Vitals [...] Image Optimization with Astro on Vercel is supported out of the box with Astro
ISR / revalidation
Supported
Incremental Static Regeneration (ISR) allows you to create or update content without redeploying your site. [...] To enable ISR in Astro, you need to use the Vercel adapter and set isr to true in your configuration in astro.config.mjs
edge_middleware
Supported
Deploying middleware at the Edge [...] Set to true to automatically convert Astro middleware to Routing Middleware, eliminating the need for a middleware
zero_config_deploy
Supported
You can deploy a static Astro app to Vercel with zero configuration. [...] Statically rendered, or pre-rendered, Astro apps can be deployed to Vercel with zero configuration.

What it costs to run there.
- Entry paid plan
- $20 per developer seat / month (Pro)
- Pricing model
- Per-seat subscription plus metered resource usage; CDN charges cover requests, data transfer to visitors and Fast Origin Transfer, and vary by the region a request comes from.
- When you exceed a cap
- Billed automatically: extra usage beyond the included amount or Pro credit is charged, not throttled or suspended
- Regions
- 20 compute-capable regions, from Stockholm and Mumbai to Cleveland and Cape Town; functions default to iad1 (Washington, D.C.).

Whether it suits you.
Teams building on a framework the CDN understands natively, who want a predictable per-seat cost with metered usage on top. The Git integration covers GitHub, GitLab, Bitbucket and Azure DevOps, so it drops into an existing review workflow.
Consider something else if…
The team is large enough that $20 per developer seat dominates the bill rather than the metered usage underneath it.
