It aims to make the first stage of network reconnaissance faster while allowing users to extend what happens after a port is found. It is aimed at security testers and network administrators who want a fast scanner that fits into a broader command-line workflow. The project describes support for IPv6, CIDR ranges, and file input, and offers installation through Cargo and platform package managers. ## Key Features - Scans TCP ports, with the project stating that a full port range can be scanned in as little as three seconds. - Pipes discovered ports into Nmap for follow-up analysis. - Runs scripts written in Python, Lua, or Shell. - Supports IPv6 targets, CIDR notation, and file-based input. - Includes adaptive behavior intended to tune scanning to the environment and how the tool is used. - Provides performance checks in continuous integration to catch significant slowdowns. ## Use Cases - A penetration tester can quickly identify open ports before running more detailed Nmap checks. - A security practitioner can trigger a custom script when a particular service port is discovered. - A network administrator can scan an IPv6 or CIDR range as part of an authorized inventory workflow. - A user with a list of targets can provide file input and incorporate the scan into command-line tooling. ## Our Take RustScan is an actively maintained, Rust-based reconnaissance tool with broad community contributions, though its release cadence and issue resolution times merit attention. **Good fit if:** - You want a fast port-discovery step that can feed Nmap or scripts. - Your workflow benefits from Python, Lua, or Shell scripting, or from IPv6, CIDR, and file input support. - You can meet the GPL-3.0 license terms and are comfortable installing the Rust toolchain for the officially supported Cargo route. **Look elsewhere if:** - You need a recent published release as part of your adoption process, since there has been no release in over a year despite regular commits. - Your team needs issues to be resolved quickly, as the measured median time to close an issue is lengthy. - You need a scanner that does not require Rust for the officially supported installation method. ## Project Health | Signal | Value | |---|---| | Status | **Active**: regular commits | | Last commit | 2026-11-04 (4 days ago) | | Commits, last 90 days | 57 | | Releases, last 12 months | 0 (latest 2.4.1, 2025-02-23) | | Contributors | 100+ (top contributor: 46% of commits) | | Issues closed, last 90 days | 29 (typically closed in 543 days) | | Pull requests merged, last 90 days | 50 (typically merged in 21 days) | | Project age | 6 years | Checked on 2026-11-08 with the GitHub API. ## Project Facts - Language: Rust - License: GPL-3.0 - Stars: 20.7k - Forks: 1.4k - Topics: docker, hacking, hacktoberfest, networking, nmap, pentesting, port, rust - Archived: no ## What You Need Detected in the repository: - Rust (from Cargo.toml) - A test suite and automated checks on GitHub Actions ## Getting Started Install with Cargo: ```sh cargo install rustscan ``` See the [README](https://github.com/bee-san/RustScan) and [installation guide](https://github.com/RustScan/RustScan/wiki/Installation-Guide) for package-manager and Docker guidance, configuration, and usage details. ## License in Plain Words **GPL-3.0** (strong copyleft). - Commercial use: yes - Modify and redistribute: yes - You must keep: the license notice - Share your changes: yes, the full source of anything you distribute that includes it, under the GPL - Includes an explicit patent grant from the contributors A summary, not legal advice: the LICENSE file is what applies. ## Alternatives - [masscan](https://osrepos.com/repo/robertdavidgraham-masscan): Masscan uses a C-based asynchronous scanner and its own TCP/IP stack to probe large address ranges, while RustScan is Rust-built and commonly hands results to Nmap. | Project | Language | License | Stars | Status | |---|---|---|---|---| | **RustScan** | Rust | GPL-3.0 | 20.7k | Active | | [masscan](https://osrepos.com/repo/robertdavidgraham-masscan) | C | AGPL-3.0 | 26.1k | Maintained | ## Considerations The repository is active, with regular recent commits and merged pull requests, and contributions are not concentrated in a single person. However, no release has been published in over a year, and issue closure is slow by the measured median. The README describes speed as a priority and notes performance checks, but scan results and timing will depend on the target network and environment. RustScan is GPL-3.0 licensed, so review the license obligations before incorporating or distributing it as part of another product.
