Hi, I am Marcel, an IT security professional, open-source contributor and hands-on builder from Germany.

I create tools that solve problems I encounter in real environments. My current main project is WebSSH, a self-hosted web application that provides secure SSH access and SFTP file management directly from the browser.

WebSSH includes features such as:

-Multiple simultaneous SSH sessions
-Split terminal layouts
-Persistent tmux sessions
-Broadcast commands across multiple servers
-Saved connection profiles
-SSH key management with encrypted storage
-A dual-pane SFTP file manager
-File previews and browser-based editing
-Audit logging and administrative controls
-Docker-based deployment
-Mobile-friendly access
-Tailscale SSH integration

The project is open source and available under the MIT license.

I maintain WebSSH in my spare time. That includes developing new features, reviewing security implications, fixing bugs, improving documentation, maintaining Docker images and testing updates across different environments.

Support through Buy Me a Coffee helps me spend more time improving the project and keeping it actively maintained.
