NetsCLI vs ScanSearch

NetsCLI is an open-source network scanner for discovering LAN devices, scanning TCP and UDP ports, querying DNS, and inspecting hosts. It runs on Linux, macOS, and Windows, with a desktop app, terminal UI, command-line interface, and MCP server built on one Rust core. The desktop app supports multiple investigation tabs, sortable and filterable results, exports, and scan history. Discovery can add reverse DNS, ARP cache details, MAC addresses, and device makers when the operating system has that information. Network operations in the CLI support JSON and YAML output; list commands also support CSV and Markdown. The MCP server runs over stdio and exposes structured network tools to compatible AI clients, including Claude Code and Cursor. NetsCLI is MIT-licensed and free for personal, open-source, and commercial use. Its binaries and installers are said to be checksummed and signed with Sigstore cosign. Packet capture requires separate downloads and libpcap on Linux or macOS, or Npcap on Windows. It does not provide remote administration and lacks advanced service detection, NSE scripts, and OS fingerprinting.

ScanSearch is a cloud service for on-demand network exposure checks. It runs live SYN scans and detects services on specified targets, which can be IP addresses, CIDR or country ranges, ASNs, or resolved domains. Its Nmap-based engine identifies software, versions, and protocols from more than 12,000 signatures covering over 1,200 services. Depending on enabled modules, results can add TLS/SSL details, HTTP security headers, geolocation, technology stack information, and CVE matches. Results appear in a live dashboard and can be exported as TXT, JSON, or CSV. The REST API supports JSON, webhooks, batch operations, and an official Python SDK and CLI. Separate tools automate Google dork queries and monitor attack surfaces with scheduled scans, change tracking, dashboards, and alerts. Scan data is retained for 7 days on free accounts and 90 days on paid accounts. ScanSearch requires permission for every target and describes its use as authorized security testing, network administration, and research. A free plan and trial are available; the listed paid Internet Scanner plan costs $0.30 a month, billed per kpps/month.
