Clean Express

Clean Express is a modern Usenet (NNTP) client for Apple platforms.
Read threads, download attachments, and post articles in one focused workflow.

Connect with confidence
- Add one or more NNTP servers with Plaintext, STARTTLS, or SSL/TLS (Implicit).
- Review self-signed certificate fingerprints and choose whether to trust them.
- Store server credentials securely in Keychain-backed storage.

Stay on top of busy groups
- Browse server groups, search and manage subscriptions, and filter your sidebar.
- Sync thread headers with incremental progress updates.
- Sort by recent activity or original post, then filter by All, Unread, or Threads with Unread.
- Expand or collapse branches, watch threads, and move quickly with keyboard or swipe navigation.
- Mark messages, threads, or full visible ranges as read.

Work with attachments
- Preview supported attachments inline, including text, images, and PDFs where available.
- Decode common Usenet binary content, including yEnc and uuencode payloads.
- Add large downloads to a dedicated queue with staged progress, retry/cancel, and clear-completed actions.
- Save completed downloads to files, with queue state restored after relaunch.

Compose and post without losing your place
- Create new posts and replies with quote-aware reply context.
- Keep drafts automatically and resume after relaunch.
- Add attachments from the file picker or drag and drop.
- Choose MIME, yEnc, or uuencode posting formats based on server or community preferences.
- Send in the background with visible posting progress.
