ReSeeder

Instant torrent seeding without rehashing

Website · Download · Русский

---

ReSeeder is a free Windows utility that instantly seeds movies and TV shows you already have on disk to Kinozal, RuTracker and other trackers — skipping hash checks. It finds already-downloaded files on your drive and starts seeding in seconds (cross-seeding existing data). No rehashing, no re-downloading.

Features

• ⚡ Instant cross-seeding — put already-downloaded files back into seeding in seconds, without re-checking hashes.
• 🔎 Finds renamed files — matches your files to torrents even if they were renamed, by hashing only the first and last piece.
• 📦 Seeds what you have — seeds the files actually present on disk, no re-downloading. Your files are never renamed, moved or modified.
• 🔗 One file, multiple trackers — a single local file can be seeded to several trackers at once.
• 🗂️ Auto-sort by tracker — automatically organizes your seeds per tracker.
• 🗺️ Peers map — see who you are seeding to: country, city and provider.
• 🛠️ For tracker admins — passkey and API support for tracker integration.

Windows 10 / 11 (x64) · Free · No .NET installation required (self-contained) · No telemetry.

👉 reseeder.app — the app updates itself.

Build from source

You need Windows 10/11 x64, Visual Studio 2026 with the .NET desktop and C++ (C++/CLI, v145) workloads, the .NET 10 SDK and vcpkg (VCPKG_ROOT set to your clone).

1. Torrent engine (C++/CLI wrapper over libtorrent 2.0.12 + OpenSSL):

   cd engine\LibtorrentDotNet
   %VCPKG_ROOT%\vcpkg install --triplet x64-windows
   build.bat
   

   The first vcpkg install builds Boost and takes a while. libtorrent and OpenSSL are pinned by the overlay ports in overlay-ports\.
2. The app: dotnet build ReSeeder.sln -c Release, or publish.bat nopause for a portable self-contained build in publish\ReSeeder\ (ReSeeder.exe in the root, everything else in Data\).

GeoLite2 databases are not in the repo: the app downloads them from api.byfox.dev — Settings → Updates.
