Udeler Reborn

Udeler-Reborn is an open-source, privacy-first cross-platform desktop application designed to securely archive your purchased online courses for offline study. Built as a zero-trust modernization of legacy clients, it features a hardened Electron architecture, automated smart storage tiering, and local cryptographic vaults.

Udeler-Reborn provides an elegant, robust GUI client to safely backup your entire learning library into organized local directories, ensuring your education remains permanently accessible, offline, and under your absolute control. As modern digital platforms shift away from open media formats, students and data archival enthusiasts face losing access to materials they legitimately own. Udeler-Reborn fixes this.

Unlike outdated forks that suffer from broken API endpoints and memory leaks, Udeler-Reborn has been completely modernized with a secure, type-safe codebase. It acts as an orchestrator that seamlessly handles authentication, batch playlist generation, media fetching, and structure preservation without relying on untrusted third-party servers.
