Velocir
A download manager built around speed, control, and reliability.
Velocir is a Rust-powered download manager built to handle complex transfers. From segmented downloads to multi-network scheduling, its engine is designed to give users more control over how files move from the internet to their devices.
The engine handles segmented downloads, transfer scheduling, network management, and file acquisition. Around it sit a desktop application, browser integration work, and diagnostics for understanding what each transfer is doing.

1.1
Segmented, parallel downloads
Eligible files are divided into byte ranges and the pieces are fetched concurrently. The engine is built on a 32-part segmented architecture with its own scheduling logic.
-
1.2
Multi-network transfer scheduling
Different pieces of one download can travel over separate network interfaces, such as Wi-Fi and a tethered phone. Coordination happens on your machine, and every connection goes directly to the original source.
-
1.3
Browser download integration
Ongoing work on intercepting browser downloads, URL handling, resource discovery, and workflows for files that cannot be fetched through a simple direct link.
-
1.4
Transfer management and diagnostics
The architecture is built around managing concurrent transfers, network failures, resource identity, integrity verification, and recovery, with diagnostics that show what a transfer is actually doing.
-
1.5
Local processing
A Tauri desktop application with companion command-line tools. Transfers are coordinated on the device itself, not through a service operated by Avelorium.
NoteMulti-network transfers work at the application level: separate connections over separate interfaces, coordinated locally. This is not packet-level link bonding, and compatibility depends on the source and its authorization requirements.
