Christos A.Daggas

I build the Linux apps I wish already existed, then give them away.

My job is keeping people, servers and networks running. My other job, the one nobody assigned me, is fixing the small frustrations of using Linux every day: a firewall you can actually read, dictation that never leaves your computer, a cleaner that shows its work before it deletes anything. All of it is free and open source.

ls ~/apps

Free apps for the Linux desktop.

Each one takes something that used to mean a terminal and a man page, and turns it into a window you can understand at a glance. Every app is open source on GitHub, with the latest release and install instructions for your distribution.

Speech to Text

Fast, private speech recognition that runs on your own computer. Capture a thought, draft a message or transcribe an audio file, and watch your words appear as you speak, with GPU acceleration and no cloud service in between.

  • Output styles for plain text, messages, emails, notes and code
  • Translation and transcription of audio files
  • Dictation, a custom dictionary and searchable history
  • LLM and API integration for your own workflows

Click the green microphone, then switch the output style.

Security Center

Redesignedv1.8.2

A complete security center for Linux. See whether your firewall is protecting you, which apps are talking to the internet and where in the world they connect, then manage zones, services and ports without touching the command line.

  • Firewall status, zones and services at a glance
  • Live connections per app, with country and throughput
  • Listening ports and network exposure overview
  • Quick actions for common administrative tasks
  • Real-time network activity monitoring

Data Cleaner

Redesignedv1.0.0

Safe and transparent system cleaning. Data Cleaner shows you how your disk is used, scans only the targets you enable, and lets you review everything in the log before a single file is removed. It was previously called File Cleaner.

  • Disk usage overview for every mounted drive
  • Smart duplicate file detection
  • Cache, temporary file and package manager cleanup
  • Safe mode with confirmations and a detailed log
  • System Maintenance
  • Disk Management
  • Optimization

Bulk Rename Tool

Rename hundreds of files in one go without writing a script. Stack simple rules such as remove, insert and numbering, and the preview shows every new name before anything changes on disk. If you change your mind, undo puts every file back.

  • Stackable rules: remove, insert, replace, numbering and case
  • Regular expression support
  • Live preview, with name conflicts caught before you apply
  • Undo and redo for every rename
  • File Management
  • Productivity
  • Batch Operations

Edit a rule with the pencil, add one with +, then press Rename. Undo puts everything back.

Network Manager

Your connection, at a glance. Network Manager shows which profile is active, whether the NetworkManager service is healthy, your current address, gateway and DNS, and live traffic, with one-click switching between saved profiles for home, office and travel.

  • Quick network profile switching
  • Wi-Fi and Ethernet management
  • VPN configuration and control
  • Connection history and favorites
  • Live network activity and service status

More tools for Linux.

PeekIn

New

Face authentication for Linux. Look at your webcam to unlock sudo, the GNOME login screen and the lock screen, with your password always there as the fallback.

  • Face enrollment, camera selection and recognition tests in one app
  • Works with regular webcams and compatible infrared cameras
  • Local processing with encrypted face models, using the TPM when available
  • Optional automatic screen lock when you walk away
Download on GitHub Rust · GTK4 · MIT

Face login is a convenience, not a replacement for password-level security.

Cockpit Remote

New

A browser-based remote desktop for your Linux host, right inside Cockpit. Built on GNOME Remote Desktop, its traffic travels through Cockpit's own authenticated, encrypted connection, so no extra ports need to be opened.

  • Detects VNC and RDP endpoints, with service health checks
  • Full-screen, view-only and scale-to-fit console modes
  • Two-way clipboard sync and per-connection credentials
  • Service logs, and an interface in six languages
Download on GitHub TypeScript · React · LGPL-2.1

vLLM Server Manager

A management app for vLLM AI model servers. Start and stop model instances and watch performance, memory and resources in real time.

About me

I fix other people's systems for a living, and build my own for the love of it.

I work where design meets infrastructure. As an IT Manager in Athens, I spend my days on networks, servers and the people who depend on them, and I bring a web designer's eye to all of it. I believe software should explain itself, which is why my apps show you exactly what they are doing before they do it.

I work primarily on Fedora. It's my daily workstation, and every app here is built, tested and used on Fedora with GNOME before anyone else sees it. Open source is how I give back: when a task felt harder than it should, I wrote an app for it: Security Center because a firewall shouldn't need a manual, Speech to Text because your voice shouldn't need the cloud, PeekIn because a laptop should know its owner's face. They are all free, written to feel at home on GNOME.

PrestaShop modules

Commercial modules, built to last.

E-commerce is the other half of my work. I've built about 30 PrestaShop modules for commercial shops, each one written to stay fast and stay easy to maintain long after launch day. They are coming to the public soon.
