The record

Purpose: Checks TCP ports on the public IP address making the request and reports whether ports are open, closed, or filtered.
Scan modes: Fast scan checks 32 common ports in about 20 seconds; deep scan covers all 65,535 TCP ports and includes service version detection.
Target restriction: The scan target is set from the visitor’s connection, and the site does not let users enter another IP address.
API: The API supports polling endpoints and a streaming v2 endpoint, requires no signup or API key, and supports IPv4 and IPv6.
Integrations: The MCP server provides fast_scan and deep_scan tools and lists setup instructions for Claude Code, Cursor, Windsurf, Claude Desktop, VS Code, Gemini CLI, Codex, and ChatGPT.
Automation: The API supports webhook callbacks on scan completion or failure and describes CI/CD pipelines and monitoring scripts as use cases.
Limits: The API supports TCP scans only, does not allow arbitrary target IPs, and scan results expire after 24 hours.
Rate limits: The API documents limits of 2,000 fast scans per ASN per hour, one deep scan per IP per five minutes and 200 per ASN per hour, plus an edge limit of 30 requests per IP per minute.
Data handling: The site says its scanning nodes are in the Netherlands, France, and the UK, and scan results are stored in an EU database.
Retention: The site says scan metadata is logged for 180 days, detailed scan results are kept for 24 hours, and a seven-day history of completed scans is visible from the same IP.
Privacy: The site says it has no user accounts, sends no data to third parties, and uses a self-hosted Plausible instance for aggregate page views without cookies or personal data.
Limitations: The homepage says the scan is a basic port check, not a security audit, and results may be incomplete or inaccurate.
Intended users: The API documentation describes use for self-checking by servers, CI/CD pipelines, and monitoring scripts.
