LinkSo is a short-link service with direct, password-protected and five-second advertising redirects. A shared Flutter app runs on Web, Android and iOS; the API is built with Rust, Axum and PostgreSQL.
- Create direct, password-protected and advertising short links with custom slugs, expiration, titles and tags.
- Manage links, enable or disable them, export QR codes and review owner-scoped analytics.
- Register accounts, verify email, recover access and manage active sessions and profile settings.
- Use responsive Web, Android and iOS clients with English/Russian localization and light/dark themes.
- Protect redirects with server-side timers, one-time tickets, rate limits, moderation and privacy-first aggregated metrics.
- Run the complete stack with PostgreSQL, Mailpit, Rust and Nginx through Docker Compose.
The screenshots use local demonstration links, not publicly hosted short URLs.
