Prism 1.1.7 — One beam. Many rays.

A fast, open-source download manager for Windows, Linux and macOS, with browser integration
and video downloads.

What's new in 1.1.7

• AI models from Hugging Face (#29).
  Download a model by its name (like Qwen/Qwen3-8B), a link or a search: the new model button in
  the toolbar, or Settings › AI models. Prism lists the model's files and picks the ones you need:
  one version of a GGUF model (Q4_K_M unless you choose another), or the weights in one format with
  the configs and tokenizer beside them. The files go into a Hugging Face queue and download one
  after another, each over many connections, and every weights file is checked against the SHA-256
  Hugging Face lists. Files you already have are skipped.
  • Gated and private models work with an access token (Prism also uses the one hf auth login
    saved). The token goes only to the Hugging Face server, never to the download servers it
    redirects to, and it isn't stored with the downloads.
  • The server can be a mirror such as hf-mirror.com (or HF_ENDPOINT).
  • A link to a model's page opens the model window; a link to a file's page downloads the file.
  • Thanks to Vasili-Sk for the idea!
• Turkish (#31): 9 languages
  now. Thanks to merihfiliz for asking!
• Windows on Linux (#30): on KDE
  Plasma, a Prism window sometimes stayed empty. Windows are now shown as soon as they are created,
  as on macOS, instead of after their first paint.
• The window's background matches the theme
  (#21). On Linux (and Windows 10),
  where there's no glass behind the window, the window turned see-through and showed the desktop
  behind the light or dark theme; it now keeps its own background. On Windows 11 the glass now also
  switches when Windows changes between light and dark while Prism is open.
• Linux and macOS: if Prism was ended while downloading (a crash, or killed), the computer could
  stay unable to sleep until a restart. Keeping it awake now ends together with Prism.
• The Chrome Web Store extension (1.1.0) keeps working as it is; nothing to update there.

Prism 1.1.6

• The light theme is fully light on Windows
  (#21); Brave Origin connects on
  Linux and macOS; VK videos (#25);
  YouTube while signed in (#23); the
  Firefox Add-ons ID.

Prism 1.1.5

• Links to .torrent files open Add torrent instead of failing
  (#20).

Prism 1.1.4

• The window opens again on Linux
  (#18).
• Lighter in the tray (#11):
  after a minute there, Prism closes its window to free the web view's memory.
• Compact view (Settings › Appearance); magnet links and .torrent files open in Prism on Linux;
  with Close button hides to the tray off, the close button quits Prism.

Prism 1.1.3

• Downloads from sites with a robot check (like softpedia.com) are left to the browser
  (#14), and an error page is
  never saved as your file.
• Remove downloads whose files were deleted (Settings › General, off by default).

Prism 1.1.2

• Arabic (the whole window mirrored right to left) and Indonesian: 8 languages now.
• Copied links without popups: turn off Ask before adding copied links in Settings › General.
• A fuller torrent window (category, queue, free space) and Delete with files asking once.

Prism 1.1.1

• Czech, German, Spanish, French and Italian, besides English; Prism follows your system's
  language (Settings › General › Language).
• The portable version finds the browser extension again
  (#12); torrents with several
  files get their own folder; Start minimized and starting with the computer keep Prism in the
  tray; Zen and Firefox with new profiles connect on Linux; the rpm works with RPM Fusion's ffmpeg
  (#10).

What's inside

• Multi-connection engine written in Rust: up to 32 connections per file, dynamic
  segmentation (a freed connection splits the largest remaining range), automatic
  detection of server connection limits, writes straight into the final file.
• Resume that survives crashes: pause, quit, lose power — Prism continues where it
  stopped and validates the file against the server.
• Browser integration: click a download link and Prism takes over. A Download video
  button over video players, a popup listing every stream on the page, right-click menus.
• Video and audio: YouTube and every site yt-dlp supports. Choose MP4 + quality (up
  to 8K/HDR) or MP3 only. Subtitles, chapters, thumbnails, SponsorBlock.
• More protocols: FTP/FTPS, HLS and DASH streams, BitTorrent and magnet links.
• Organisation: categories, queues with schedules and speed limits, actions when a
  queue finishes (sleep, shut down…), site grabber, batch downloads, clipboard monitor.
• AI models from Hugging Face: by name, link or search, the right files picked for you,
  checked by SHA-256.
• Liquid-glass UI with dark and light themes, six accent colours and a mini window.

Known limitations

• The installers are not code-signed (signing certificates are paid):
  • Windows SmartScreen: click More info → Run anyway.
  • macOS: run xattr -dr com.apple.quarantine /Applications/Prism.app once (or System
    Settings → Privacy & Security → Open Anyway). In-app updates don't need this again.
• Firefox: Prism isn't in Firefox Add-ons yet. Its extension is loaded by hand, and Firefox
  keeps unsigned add-ons only until restart, except in Developer Edition / Nightly / ESR.
• macOS builds are produced by CI and tested there; feedback from real Macs is very welcome.
• Flatpak browsers on Linux can't talk to native apps (a browser sandbox limitation) — use
  the deb/rpm version of your browser.
