Zeus and the alternatives
Comparisons by category. Products differ, so where something varies we say so.
How is Zeus different?
Browsers and desktop download managers are built for a person clicking links; command-line tools such as curl and wget are built for scripts. Zeus is designed for an AI assistant doing the downloading on your behalf: it offers MCP tools, resumes after crashes, can take over failed browser downloads, and asks you before using any login, because an AI must not be able to approve.
Comparison table
| Feature | Browser downloader | Desktop download manager | AI agent running curl or wget | Zeus |
|---|---|---|---|---|
| Your AI assistant can use it (MCP) | No | Rarely | Partly: the agent runs commands | Yes |
| Continues after a crash or reboot | Sometimes | Usually | Only if the command is rerun correctly | Yes, from a crash-safe journal |
| Downloads files behind a login | Yes (it is your browser) | Often, by taking cookies from the browser | Only with cookies copied by hand | Yes, per site, after you approve |
| Asks you before using a login | Not applicable | Usually not | No | Always, and only you can answer |
| Finishes downloads the browser gave up on | Retry from the start | Some can capture new downloads | No | Yes, from the bytes already saved when possible |
| Checks every file’s fingerprint | No | Some, on request | Only if scripted | Yes, SHA-256 and BLAKE3, with a receipt |
| Open source | Varies | Varies | Yes (curl, wget) | Yes, Apache-2.0 |
| Sends usage data to its maker | Varies | Varies | No | No |

Zeus and your browser
When a long browser download fails, the browser usually has to start over, and your AI cannot use the browser’s downloader at all. With the Zeus extension, a failed download gets a “Finish with Zeus” offer, and Zeus continues from the bytes the browser already has when the server allows it.
Zeus and download managers
Desktop download managers resume and split downloads well. They were not designed for an AI caller, and some read cookies from the browser to handle logins without asking each time. Zeus gives your AI a small, safe set of tools, borrows a session only for a site you approve, keeps it in memory for at most 15 minutes, and records every use.
Zeus and curl or wget
curl and wget can resume downloads when given the right flags. An agent driving them has to remember those flags, handle expired links by itself, and get cookies by copying them into a command or a file, which is the kind of secret an AI should not hold. Zeus handles resuming and sessions itself and does not give your AI the cookies.
Zeus and Ogun
Zeus is for everyday downloads with your AI. Ogun, also by Verne, is a developer platform for data pipelines, data mining and agent benchmarks, built on the same download engine. Engineers building datasets should look at Ogun.

Try the pre-alpha
Zeus 0.0.1a is a pre-alpha release: try it in your browser on a private sandbox, or download it for Windows or Linux. Expect rough edges.
