Features

Built for speed, designed for control

Everything you need from a download manager, without the bloat.

Parallel Chunking

Splits files into chunks and downloads them concurrently. Up to 16 parallel streams for maximum throughput.

Resumable Transfers

Never start from scratch. Pause and resume downloads across sessions with crash recovery.

YouTube Integration

Intercept YouTube links and choose quality — 4K, 1080p, 720p, or audio-only. Powered by yt-dlp.

Cross-Platform

Use the CLI or web UI. All share the same SQLite database — instantly synced.

Browser Extensions

Capture downloads from Chrome, Edge, or Firefox. Right-click any link and send it straight to Grabr.

Live Speed Meter

Real-time download speed with EMA smoothing, ETA calculation, and a chunk-level progress visualizer.

Unified Database

SQLite-powered. Every platform reads and writes to the same ~/.grabr/grabr.db file. No cloud, no tracking.

Download Queue

Configure max concurrent downloads. Jobs automatically queue and process as slots become available.
