li-nk.me: A Modern Universal Links Platform

Universal Links are essential for mobile app marketing, enabling seamless deep linking from web to native apps. However, building and maintaining this infrastructure is complex, requiring Apple App Site Association files, Android Asset Links, custom domain management with SSL certificates, platform detection, and analytics.

li-nk.me is a managed SaaS platform that handles this complexity. It transforms long URLs into short, smart links that detect user platforms and route accordingly. On mobile, links attempt to open native apps via Universal Links or App Links. If the app isn't installed, users see a hosted fallback page with App Store buttons and QR codes.

The platform supports custom domains with automatic SSL certificate provisioning via Caddy's on-demand TLS. No manual certificate management is required. Links include UTM parameter handling, social card generation with custom Open Graph metadata, and basic analytics tracking.

The architecture runs on a single VPS: Caddy handles TLS termination and routing, while an Express edge service manages link resolution, well-known file serving, and analytics. A Next.js portal provides the admin interface. Data is stored in SQLite with automated backups.

The platform includes team collaboration features with multi-tenancy, roles, and invitations. Billing is handled through Stripe with multiple plan tiers, each with different entitlements for clicks, seats, and custom domains. The system enforces limits automatically.

li-nk.me provides REST APIs for programmatic management, vanity slugs for branded links, and a debug page for troubleshooting. SDKs for iOS, Android, React Native, Flutter, and Web are open source under Apache 2.0.

For developers and marketers who want Universal Links without vendor lock-in or self-hosting complexity, li-nk.me offers a turnkey solution that scales from solo projects to enterprise campaigns.
