Why zanzibarr

An engine, not a downloader

Everything heavy — parsing, yEnc, archive surgery, NNTP — is Rust. Everything you touch is Flutter. The engine only ever fetches the slices you actually watch.

Under the hood

How it works

Every seek position is mapped to the exact Usenet segments that hold it — decoded, verified and served through a lazy, range-aware local stream.

.nzb ──▶ NZB parser ──▶ segment map (yEnc begin/end) │ NNTP pool (TLS, pipelined) │ fetch → yEnc decode → CRC32 verify │ archive layer (RAR5 / 7z STORE·AES → virtual file) │ localhost HTTP server (Range requests) │ libmpv / media_kit

Support the project

zanzibarr is free and open source, built in spare time. If it saved you a download queue, you can buy the next coffee that funds the engine — one-off or monthly, both keep the commits coming.
