Point it at a domain and it concurrently gathers DNS, WHOIS, TLS, security, tech-stack and SEO intelligence, then lays it out across tabs — with a live activity log, a country map and a server-status panel that stay pinned in place.

No paid APIs. Everything runs off free, public endpoints and the standard library: ip-api.com for geolocation, Cloudflare/Google DoH and dig against public filtering resolvers for blocklist checks, the system whois, and stdlib ssl/socket. Country borders are embedded (Natural Earth), so even the map needs no tile service.

Features

Ten tabs, scanned concurrently and rendered live as each module finishes:

• DNS — records plus email authentication, folded into one tab.
  • A / AAAA / NS / CNAME / SOA / MX / TXT / CAA / DS / DNSKEY records
  • DMARC (_dmarc) and DKIM (probes ~40 selectors, each labelled with its email provider)
  • SPF all qualifier, and an Email Spoofing verdict (Protected / Weak / Vulnerable) computed from DMARC enforcement, not SPF alone
• Whois — parsed system whois, with rich gTLD and ccTLD field support.
  • Registrar, registration / expiry dates, nameservers
  • Per-contact details where published
• Subdomains — discovered natively, no third-party enumeration services.
  • TLS certificate SANs
  • socket probes of common subdomains
• SSL — the live TLS certificate, parsed from the handshake.
  • Issuer, subject, SANs
  • Validity window, trust and expiry
• Security — four checks, each a sub-table.
  • WAF detection — passive header/cookie fingerprinting plus an active probe that sends obvious attack payloads to see if it gets blocked (names Cloudflare, Sucuri, Akamai, ModSecurity, …)
  • Open ports — TCP connect scan of common ports
  • HTTP security headers — CSP, HSTS, X-Frame-Options, … present or not
  • Blocklists — status across public filtering resolvers (AdGuard, CleanBrowsing, Cloudflare, Google, OpenDNS, Quad9)
• Headers — the full set of HTTP response headers.
• Tech — technology-stack detection via Wappalyzer.
  • Each technology with its category, confidence, groups and version
• SEO — everything on-page that search engines read.
  • Title / description with length hints, H1–H3, social links
  • Top keyword n-grams (1 / 2 / 3-word)
  • robots.txt and declared sitemaps
  • JSON-LD structured data
• Sitemap — the site's URLs as a clickable path tree, no crawling.
  • Discovered from sitemap.xml, recursing into nested sitemap indexes
  • Rebuilt into a folder tree keyed by URL path
• Links — links found on the page, with their anchor text.
  • Internal and external, split into sub-tables

Alongside the tabs, three fixed panels:

• Activity Log — a running narration of the scan: what each module found, what came back empty and what broke, so every headline result is visible without switching tabs.
• Country map — real country outlines auto-framed around the server's location, drawn with braille characters (+ / - to zoom).
• Server — online status and response time, the final URL after redirects, IP, geolocation, ISP, AS, hosting provider and detected CMS (name and version). When many sites share the server's IP, it flags the address as shared and counts how many distinct domains resolve to it (via a free reverse-IP lookup).

Requests to the site being scanned wear a coherent desktop-Chrome identity — a real User-Agent plus the headers Chrome actually sends beside it — picked once per scan and reused for every request, and reported in the Activity Log. This is about getting the real page back rather than a WAF block page, and it only defeats naive User-Agent filtering: the TLS and HTTP/2 fingerprints are still those of requests, so enterprise bot management sees straight through it. Third-party lookups (ip-api, DoH) keep an honest scanner User-Agent.

Installation

Requires Python 3.11+.

The easiest way is with pipx (or uv), which installs webscan into its own isolated environment:

pipx install web-scanner
# or
uv tool install web-scanner

To install the latest unreleased code, point either tool at the repo instead: pipx install git+https://github.com/iamramizk/web-scanner.

From source (development)

git clone https://github.com/iamramizk/web-scanner.git
cd web-scanner
python3 -m venv .venv
source .venv/bin/activate     # Unix/macOS  (.venv\Scripts\activate on Windows)
pip install -e .

Usage

webscan example.com

You can also run it as a module (python -m webscanner example.com), or from a source checkout without installing (python app.py example.com).

Press s inside the app to save every tab to CSV. When installed, results are written to a ./<domain>_<timestamp>/ folder in your current directory.

Updating

pipx upgrade web-scanner

If you installed from Git, pipx upgrade won't see new commits (the version is unchanged), so reinstall from source instead:

pipx install --force git+https://github.com/iamramizk/web-scanner
