Astro SaaS starter with Facebook Login
Ship Facebook Login in your Astro app with sessions, protected routes, and email auth working together. Skip the callback wiring, cookie edge cases, and deploy surprises that stall most OAuth rollouts.
The problem
Rolling your own Facebook Login in Astro means OAuth callbacks, session storage, CSRF edges, and protected routes that break the first time you deploy to production.
Building it yourself
Scaffold Astro, find a Facebook Login 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
- Facebook Login wired with server-side sessions
- Protected routes and admin headers included
- Combine with Google, GitHub, or email auth in one app
How teams ship with this kit
- 1
Clone and configure
Add your Facebook Login keys and provider settings to the included env template. The Astro app boots with the integration active.
- 2
Customize product flows
Adjust pages, pricing, and onboarding on top of pre-wired routes. Auth, webhooks, and integration helpers stay intact.
- 3
Deploy with included configs
Use the bundled Vercel, Cloudflare Workers, or Node deployment setup. Sessions and webhooks are tuned for production, not just localhost.
- 4
Swap providers later
Client wants a different payment processor or database? Change adapters through config instead of rewriting your Astro app.
Also ships with every Astro kit
- Stripe or Polar billing
- Magic-link email
- Protected admin routes
- Deploy configs
Common questions
Is this only about Facebook Login?
No. The Astro kit is a complete SaaS foundation. Facebook Login 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 Facebook Login guides for Astro and SvelteKit too.
