Astro sends zero JavaScript to the browser unless a component asks for it, and that one decision shapes the whole skill set. We provide Astro developers who know where it saves time and where it gets in the way. If you would rather have the site built for you, see our Astro development services.
What do we vet in an Astro developer?
- Islands. Choosing between
client:load,client:idle,client:visibleand static rendering, and mixing React, Vue or Svelte components in one page without shipping three runtimes by accident. - Content collections. Typed schemas with Zod, loaders for local files or remote sources, and how to keep builds fast as collections grow.
- Rendering modes. Static output, on-demand rendering with an adapter, and server islands for personalised parts of an otherwise cached page. Candidates must say when each is the right call.
- Actions and endpoints. Server-side form handling and API routes, with validation.
- Integrations and hosting. Sitemap, image handling, adapters for Vercel, Cloudflare, Node or static hosting, and view transitions without breaking scripts.
- Upgrades. Astro majors arrive often, and the current line is Astro 7. We ask how a candidate plans a version upgrade for a large site.
A common trap is pulling a heavy UI library into every page because it was convenient once. We look for people who measure the output.
When is Astro the right choice?
Astro fits marketing sites, documentation, blogs and content platforms with a few interactive parts. It is less natural for a fully interactive app, where Next.js is usually the better base. Our Next.js vs Astro vs Remix comparison works through the decision.
This site is itself built on Astro, with hundreds of content pages and a CMS behind it.
What would an Astro developer do first?
- Move a React single-page marketing site to static Astro pages. In our B2B SaaS case study, this took LCP from 4.2s to 1.4s with a Lighthouse performance score of 98.
- Define content collections and validate front matter in CI.
- Connect a headless CMS and set up draft previews.
- Build a block-based component library for the marketing team.
- Add an on-demand route for a form or personalised element.
What do Astro projects get wrong?
The common failures are quiet ones. A framework component gets hydrated with client:load when client:visible would do. Content collections are skipped and front matter drifts between files. Images go through no pipeline at all. Or the project stays on an old major version until the upgrade becomes a rewrite. We screen for developers who check the built output, read the page weight in the network panel and keep upgrades small and regular.
How do you engage an Astro developer?
You can take a dedicated developer, extend your team through IT staff augmentation, or hand over a scoped project with a dedicated team. Our frontend rates run from $50 to $150 per hour, and engagement starts after a short intro call.
