Astro SaaS starter with Cloudflare R2
User uploads in Astro need auth checks, pre-signed URLs, and sane defaults. Cloudflare R2 is wired with authorized upload routes so you are not building file plumbing in week one.
The problem
File uploads with Cloudflare R2 in Astro need auth checks, pre-signed URLs, and MIME validation, work that rarely belongs in week one of a new SaaS.
Building it yourself
Scaffold Astro, find a Cloudflare R2 tutorial, wire env vars, fix auth sessions, then repeat for billing and email. Most teams lose weeks before the stack deploys cleanly or handles real users.
What you get out of the box
- Pre-signed upload URLs for R2
- Authorized upload component included
- Swap to S3 or Supabase Storage later
How teams ship with this kit
- 1
Clone and configure

- 4
Swap providers later
Client wants a different payment processor or database? Change adapters through config instead of rewriting your Astro app.

Common questions
Is this only about Cloudflare R2?
No. The Astro kit is a complete SaaS foundation. Cloudflare R2 ships alongside auth, billing, email, analytics, storage, and deployment so you are not assembling the stack from scattered tutorials.
Can I see it working before I buy?
Yes. The live demo runs the same Astro starter with real auth and billing flows. Open the demo, click through signup and checkout, then compare with your timeline.
What if I need Astro or SvelteKit instead?
LaunchFast ships the same integration surface in all three frameworks. Related links on this page point to the Cloudflare R2 guides for Astro and SvelteKit too.
