# Astro on Vercel

Canonical: https://inetgeek.com/stacks/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 requires from the platform underneath it, and what Vercel publishes about each. Vercel documents 4 of the 4.

| Requirement | Vercel | Why it matters |
| --- | --- | --- |
| 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. |
| 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. |
| 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

- **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 ([source](https://vercel.com/docs/frameworks/frontend/astro))
- **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 ([source](https://vercel.com/docs/frameworks/frontend/astro))
- **isr**: 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 ([source](https://vercel.com/docs/frameworks/frontend/astro))
- **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 ([source](https://vercel.com/docs/frameworks/frontend/astro))
- **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. ([source](https://vercel.com/docs/frameworks/frontend/astro))

## What it costs to run there

|  | Vercel |
| --- | --- |
| 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.
