Every feature, honestly described.
No "military-grade" marketing. Just the protocol-level capabilities, with the verifiable numbers behind them.
01 / Security
Encryption you can audit.
AES-256-GCM end-to-end
Files are encrypted on your machine before they hit your Usenet provider. Without the share link's key, the bytes on Usenet are random noise.
Three share types
Public, password-protected, or recipient-keyed. Private shares restrict decryption to specific recipients by public key — even with the link, others get useless ciphertext.
No vendor sees your files
We don't see your files, share links, recipients, or usage. We can't — there's nothing on our infrastructure to see.
02 / Speed
Built for wire-speed.
60 concurrent NNTP connections
Matches per-IP caps at Newshosting, Tweaknews, Eweka. Saturates gigabit uplinks where the provider supports it.
Custom-modified NYUU upload
Tuned for batch performance and resume safety, not generic NZB posting workflows.
Native C++ downloader
Not a Python re-implementation. Sustained 172 files/sec in our most recent consumer-side integration smoke.
03 / Reliability
Engineered for don't-touch-it.
SHA-256 verified at every step
Every file is hashed pre-upload and re-hashed post-download. Mismatches trigger automatic re-fetch from redundancy.
Resume-safe
Network drops, app crashes, even MSI reinstalls don't lose progress. The auto-resume picks up exactly where it stopped.
Auto-repair from redundancy
If a Usenet article is missing, the app pulls a redundant copy. If that's missing too, you get an operator-actionable error — not silent corruption.
Verified at million-file scale
1,005,072 files / 97 GB transferred end-to-end with 190/190 SHA-256 spot-check matches across all categories. Zero data corruption.
No file-size limit
Tested with 1 GB and 2 GB individual files inside a 97 GB share. The architecture has no theoretical cap.
No expiry
Files persist as long as your provider retains the newsgroup — typically 4000+ days at major providers.
04 / Convenience
Operator-friendly.
Bring your own provider
Works with any provider that carries the alt.binaries.* hierarchy. We don't resell bandwidth or lock you in.
Cross-platform
Windows MSI, macOS .zip (Intel + Apple Silicon), Linux .tar.gz / .deb / .rpm. Single install, browser dashboard at http://127.0.0.1:8386/.
Open source backend
The Python + C++ engine is public on GitHub. Audit it, fork it, contribute.
Recipient learning curve = zero
They paste a link. The app does everything. No NZB files, no par2, no Usenet client to install.
