The problem

When files are deleted, the data often remains on disk until overwritten. Traditional recovery tools like TestDisk require CLI expertise, Recuva is Windows-only, and commercial solutions cost hundreds of dollars per license. Most require large runtimes (.NET, Python, ncurses) and offer no remote access — you must sit at the machine. For forensic and IT teams, this means slow response times and complex deployments.

The solution

OmniRecover is a 76KB binary that scans raw disk images or devices sector-by-sector, detecting 13 file types via magic byte signatures with end-marker recognition. It auto-detects connected devices (USB drives, NVMe SSDs, SD cards) with model names and sizes. An embedded web dashboard on port 8090 lets you select scan targets, monitor progress in real-time, preview recovered images as thumbnails, play recovered audio inline, and download any recovered file — all from a browser. No CLI, no installation wizard, no runtime dependencies.

Why Bare-Metal Matters

File recovery tools need to read raw disk sectors — the lowest level of storage. A 76KB binary with zero dependencies loads instantly, uses under 3MB of RAM, and can run on any Linux system without installing anything. There is no Python to configure, no .NET to update, no library conflicts. Copy the binary, run it, open the browser. The entire tool — scanner, web server, dashboard, file server — is one file.

Use Cases

USB Drive Recovery

Plug in a USB drive, open the dashboard, click the device card (auto-detected with model name), and start scanning. Recovered photos appear as thumbnails you can click to view full-size. Download all recovered files directly from the browser.

Forensic Disk Analysis

Point OmniRecover at a disk image (.img, .dd, .raw) and scan for deleted files. 13 file type signatures detect documents, photos, audio, video, and databases. The HTTP API enables remote forensic analysis — scan a server's disk from your workstation.

IT Service / Data Recovery Shop

Deploy on a recovery workstation. Clients bring their drives, you plug them in, and the dashboard auto-detects the device. Scan, preview, and deliver recovered files — all through a clean web UI. No training needed.

Server Incident Response

After a ransomware attack or accidental deletion, deploy OmniRecover on the affected server. The 76KB binary copies in seconds. Scan the disk remotely via the web dashboard. Recover documents, databases, and media without physical access.
