Desktop downloader
Two bugs in SevenZipVolumeCallback caused multi-part RAR extraction to fail: 1. getProperty(NAME) always returned firstFileName instead of tracking the last opened volume name. 7z-JBinding needs this to compute subsequent volume filenames. 2. The first IInStream was created separately instead of through the callback's getStream() method, so the volume name tracker was not properly initialized. Verified with real multi-part RAR5 test archives (3 parts, WinRAR 7.01). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> |

Multi Debrid Downloader
Desktop downloader for Real-Debrid, Mega-Debrid, BestDebrid, and AllDebrid with fast queue management, automatic extraction, and robust error handling.
Why this tool?
- Familiar download-manager workflow: collect links, start, pause, resume, and finish cleanly.
- Multiple debrid providers in one app, including automatic fallback.
- Built for stability with large queues: session persistence, reconnect handling, resume support, and integrity verification.
Core features
Queue and download engine
- Package-based queue with file status, progress, ETA, speed, and retry counters.
- Start, pause, stop, and cancel for both single items and full packages.
- Multi-select via Ctrl+Click for batch operations on packages and items.
- Duplicate handling when adding links: keep, skip, or overwrite.
- Session recovery after restart, including optional auto-resume.
- Circuit breaker with escalating backoff cooldowns to handle provider outages gracefully.
Debrid and link handling
- Supported providers:
realdebrid,megadebrid,bestdebrid,alldebrid. - Configurable provider order: primary + secondary + tertiary.
- Optional automatic fallback to alternative providers on failures.
.dlcimport via file picker and drag-and-drop.
Extraction, cleanup, and quality
- JVM-based extraction backend using SevenZipJBinding + Zip4j (supports RAR, 7z, ZIP, and more).
- Automatic fallback to legacy UnRAR/7z CLI tools when JVM is unavailable.
- Auto-extract with separate target directory and conflict strategies.
- Hybrid extraction: simultaneous downloading and extracting with smart I/O priority throttling.
- Nested extraction: archives within archives are automatically extracted (one level deep).
- Pre-extraction disk space validation to prevent incomplete extracts.
- Right-click "Extract now" on any package with at least one completed item.
- Post-download integrity checks (
CRC32,MD5,SHA1) with auto-retry on failures. - Completed-item cleanup policy:
never,immediate,on_start,package_done. - Optional removal of link artifacts and sample files after extraction.
Auto-rename
- Automatic renaming of extracted files based on series/episode patterns.
- Multi-episode token parsing for batch renames.
UI and progress
- Visual progress bars with percentage overlay for packages and individual items.
- Real-time bandwidth chart showing current download speeds.
- Persistent download counters: all-time totals and per-session statistics.
- Download history for completed packages.
- Vertical sidebar with organized settings tabs.
- Hoster display showing both the original source and the debrid provider used.
Convenience and automation
- Clipboard watcher for automatic link detection.
- Minimize-to-tray with tray menu controls.
- Speed limits globally or per download.
- Bandwidth schedules for time-based speed profiles.
- Built-in auto-updater via Codeberg Releases.
- Long path support (>260 characters) on Windows.
Installation
Option A: prebuilt releases (recommended)
- Download a release from the Codeberg Releases page.
- Run the installer or portable build.

Releases: https://codeberg.org/Sucukdeluxe/real-debrid-downloader/releases
Option B: build from source
Requirements:
- Node.js
20+(recommended22+) - npm
- Windows
10/11(for packaging and regular desktop use) - Java Runtime
8+(for SevenZipJBinding sidecar backend) - Optional fallback: 7-Zip/UnRAR if you force legacy extraction mode

NPM scripts
| Command | Description |
|---|---|
npm run dev |
Starts main process, renderer, and Electron in dev mode |
npm run build |
Builds main and renderer bundles |
npm run start |
Starts the app locally in production mode |
npm test |
Runs Vitest unit tests |
npm run self-check |

npm run release:codeberg -- <version> [notes] |
One-command version bump + build + tag + Codeberg release upload |
One-command Codeberg release
npm run release:codeberg -- 1.4.42 "- Maintenance update"
This command will:
- Bump
package.jsonversion. - Build setup/portable artifacts (
npm run release:win). - Commit and push
mainto your Codeberg remote. - Create and push tag
v<version>. - Create/update the Codeberg release and upload required assets.
Typical workflow
- Add provider tokens in Settings.
- Paste/import links or
.dlccontainers. - Optionally set package names, target folders, extraction, and cleanup rules.
- Start the queue and monitor progress in the Downloads tab.
- Review integrity results and summary after completion.

Data and logs
The app stores runtime files in Electron's userData directory, including:
rd_downloader_config.jsonrd_session_state.jsonrd_downloader.log
Troubleshooting
- Download does not start: verify token and selected provider in Settings.
- Extraction fails: check archive passwords, JVM runtime (
resources/extractor-jvm), or force legacy mode withRD_EXTRACT_BACKEND=legacy. - Very slow downloads: check active speed limit and bandwidth schedules.
- Unexpected interruptions: enable reconnect and fallback providers.
- Stalled downloads: the app auto-detects stalls within 10 seconds and retries automatically.
