What is it?

Surge is a keyboard-driven download manager that runs in the terminal. It opens multiple connections per file (up to 16 by default), splits the file into chunks, and downloads them in parallel to use available bandwidth. It can also download from several mirrors at once, distributing workers across them with automatic failover.

Beyond the interactive dashboard, Surge can run as a headless background engine with an HTTP API, so downloads queued from several terminals or from a browser extension all go through one manager. A CLI handles automation tasks such as adding, pausing and listing downloads, and it can be installed as a system service. Remote control is supported through a token-protected API.

The project also offers an optional sequential mode that fetches files in order, useful for previewing media while it downloads. A Chrome/Edge/Brave and Firefox extension sends browser downloads to Surge.
