Prism 1.1.8 — 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 1.1.8

• Lists of links open once
  (#37). Pasting a list of links
  (Batch download › Paste a list) could open the Download links window twice: one worked, the
  other froze and couldn't be closed without quitting Prism. Dropped links and copied links could do
  the same. Each list now opens exactly one window.
• Linux: empty windows and memory
  (#36,
  #40).
  • On KDE Plasma (Wayland), a Prism window brought back from the taskbar could stay empty. Prism
    now uses WebKit's previous renderer, the known cure for empty WebKit windows there. To go back
    to the newer one, start Prism with WEBKIT_DISABLE_DMABUF_RENDERER=0.
  • After long downloads Prism gives the memory it no longer needs back to the system.
• Hide the Dock icon on the Mac
  (#34): Settings › General ›
  Hide the Dock icon. While Prism waits in the menu bar it has no Dock icon; when its window is
  open, the icon is there so Cmd+Tab works. Thanks to mehdiillala for asking!
• The Chrome Web Store extension (1.1.0) keeps working as it is; nothing to update there.

Prism 1.1.7

• AI models from Hugging Face (#29),
  Turkish (#31), Linux windows
  shown on creation (#30), and a
  window background that matches the theme.

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.
