Build on what we learn, put it to use,
and create a great future together.
thutil.com was founded on the philosophy of “Building with passion, learning by doing, and sharing openly.” We take what we study and experiment with into real-world, practical applications and open-source tools: such as serverless P2P file sharing (finfly), minimal URL shortener (short.thutil.com), and image converter (self-file-convert) to give back to the open-source community.
Our Core Principles
100% Free & Open Source
All projects are openly published on GitHub for developers and creators to inspect, contribute to, or self-host freely.
Privacy First & Zero Server Storage
User privacy is non-negotiable. Tools like finfly transfer files directly device-to-device via WebRTC P2P without saving any file on central servers.
Minimal & Distraction-Free
We eliminate clutter and bloated features to deliver clean, fast, and intuitive user experiences that just work.
Universal Device Compatibility
Built as modern web applications accessible from any modern browser across iOS, Android, macOS, Windows, and Linux without native installation.
Featured Open Source Projects & Services
AirDrop-like cross-device file sharing across local network or shared rooms with zero server storage.
