Astro on Netlify
Netlify 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 Netlify publishes about each. Netlify documents 3 of the 4.
Build allowance
Not documented
Astro prerenders by default, so most of the work happens at build time and the build allowance is the real constraint.
Concurrent builds
Personal: 1 concurrent build included, purchasable up to a maximum of 3, at $40/month per additional build
A content site rebuilds on every edit. One build slot turns a busy publishing day into a queue.

- Credit-based pricing plans | Netlify Docs ↗
“1 concurrent build included in plan with option to purchase more. Limited to 3 concurrent builds, meaning up to 3 builds can run at the same time. Ideal for using multiple agents and running projects that depend on each other. Add 1 additional concurrent build as an add-on at $40/month”

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.

- Edge Functions overview | Netlify Docs ↗
“All this dynamic processing happens in a secure runtime based on Deno directly from the worldwide network edge location closest to each user for fast response times.”

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

“When you push changes to your site's Git repository, Netlify detects your changes and triggers automated deploys, functions, and more across our global CDN.”

Astro features on Netlify
Capabilities Netlify documents specifically for Astro, with the constraint it documents alongside each.
ssr_adapter
Supported
The adapter is actively maintained by the Astro team. [...] On Netlify, on-demand rendering is powered by Netlify Functions
Image optimization
Supported
component automatically uses Netlify Image CDN to transform images on demand, without slowing down build times. The Image CDN also handles content negotiation to use the most efficient image format for the requesting client.
ISR / revalidation
Supported
Astro gives developers full control of caching headers with Astro.response.headers, allowing them to take advantage of Netlify's durable cache and Incremental Static Regeneration (ISR).
edge_middleware
Supported
middleware runs at build-time for pre-rendered pages, and on-demand for server-rendered pages. On Netlify, middleware for on-demand pages uses Netlify Edge functions behind the scenes, running on the network edge.
zero_config_deploy
Supported
Whether you use the adapter or not, Netlify automatically detects Astro in your project and provides a suggested build command

- How credits work — Netlify Docs ↗
“Once your credit balance is completely used up, all of your web projects (sites/apps) are paused and visitors to your web projects will find a Site not available page at each of your web project's URLs.”

Whether it suits you.
Teams that want Git-driven deploys onto a global CDN with a managed Postgres database built into the same platform. The free tier is 300 credits a month with a hard limit, so spend cannot surprise you.
Consider something else if…
You need to run containers or long-lived processes — Netlify does not document either.
