These are the service providers each Aextra product uses. Each table is copied word for word from that product's Privacy Policy (VibeKit, Section 8; ReMail, Section 6). When a policy's provider list changes, this page is updated in the same change.
VibeKit
| Provider | Purpose |
|---|---|
| Cloudflare | Hosting, edge compute, caching, databases, file storage, session infrastructure, usage analytics, sending of sign-in and alert emails (Email Sending), AI models (Workers AI), AI request routing (AI Gateway), and website screenshots (Browser Rendering) |
| Supabase | Customer account sign-in and project records |
| Google sign-in (only where used); Gemini model for describing design-reference websites | |
| Resend | Delivery of our product-update, onboarding and survey emails; backup delivery of transactional email |
| Airtable | The Customer's own data source, connected under credentials the Customer supplies and controls; and our own customer list (account details, progress records and survey answers) used for product-update, onboarding and survey emails |
Customers may also connect their own email provider (such as Resend, Postmark, SendGrid, or Cloudflare) to send sign-in emails for their application and, with Resend, to add form submitters to their own mailing lists, and their own hosting provider for deployments. Those providers act under the Customer's own account and terms.
