Your Own Auth, Mail
& Storage — No Lock-in.
Auth-Pro is an independent, self-hosted replacement for Supabase's auth, email, and storage features. Use your own PostgreSQL database, your own SMTP provider, and your own Cloudflare R2 bucket — with your own credentials for each.
No shared infrastructure. No vendor lock-in. No surprise billing. Full ownership of every layer.
Authentication
JWT-based signup, login, email verification, and password reset — all using your own PostgreSQL database. Your data, your server, your rules.
Email Delivery
Plug in any SMTP provider — Resend, SendGrid, Gmail SMTP, or your own mail server. Full control over every email template sent to your users.
Media Storage
Avatars and image libraries stored in your own Cloudflare R2 bucket. Auto-compressed to WebP, tagged per user, served from your CDN.
