web-check

2.3.0 open-source

Web-Check is an open source tool that provides on-demand intelligence for any website, uncovering server architecture, security configurations, and technologies in use.

Summary

web-check is an open-source reconnaissance tool, released under an open license, that runs scans against a given website to surface how it's built and where it might be exposed — IP info, SSLSSLA cryptographic protocol for encrypting network connections, now deprecated in favor of TLS but whose name persists colloquially. Cyber tools reference it when handling HTTPS or other encrypted-channel inspection and termination. configuration, DNS records, open ports, headers, cookies, traceroute, subdomains, and known vulnerabilities or advisories. It can be used via a hosted demo or deployed yourself, with documented paths to Netlify, Vercel, Docker, Render, or running from source, which suits security researchers or developers who want it wired into their own infrastructure rather than relying on someone else's instance. It sits in the OSINTOSINTOpen-source intelligence, collecting and analyzing information from publicly available sources. Investigators use it to learn about people, infrastructure or threats. and attack-surface reconnaissance space, aimed at anyone assessing a site's exposure rather than at a single named alternative. Recent additions include a vulnerabilities panel with WAFWAFA reverse proxy that inspects HTTP/HTTPS traffic and blocks requests matching known attack patterns such as SQL injection or XSS, sitting between clients and a web application to filter malicious input before it reaches the server. detection and per-check configuration, suggesting active, ongoing development.

How web-check helps

Which parts of a site's stack are visible to anyone who looks?

fingerprints server architecture, headers, cookies and technologies in use and lists them in one report

Is this domain's SSL configuration sound?

inspects the certificate chain and configuration and flags weaknesses in how it's set up

Which ports are open on this host, and what does that expose?

scans for open ports and reports what's reachable on each

What does this site's DNS actually say, and does it match what I expect?

pulls DNS records and lays them out for comparison against the intended setup

Are there subdomains attached to this domain that I didn't know about?

runs a subdomain lookup and lists what it finds beyond the main host

Is this site sitting behind a WAF, and does it have known vulnerabilities on record?

checks for WAF presence and cross-references the target against security advisories, surfacing both in a dedicated panel

Lines in monospace are the tool's own words: help text parsed from its source, or an endpoint from its API document. Under release, a line is our summary of a dated release. Under docs, it is quoted from the tool's own documentation or website. Each links back to the source it came from.

Score card

  1. Shipping velocity releases a month, last 12 months
  2. Documentation quality release-notes rubric, 0–100
  3. Breaking-change discipline how rarely a release breaks users, and notice given
  4. Maintenance risk quiet time against its own cadence, maintainers
  5. Innovation & surface new capabilities, API and MCP surface
  6. Community health
  7. Contributor trend distinct committers, this year against last
  8. Maintainer concentration bus factor now against a year ago
  9. Issue backlog trend issues closed per issue opened, 12 months
  10. Responsiveness median time to a maintainer’s first reply

Nine scores for web-check, each built from the releases, notes and API history this site tracks — and, on Researcher and Business, where it stands among every measured tool in its category and how that has moved.

Score cards are part of every paid plan.

See plans →

Each score is 0–100 on a published rubric, derived from data this site already shows. A dimension we cannot measure says so — it is never scored 0 and never enters a rank.

How this is scored
  • Shipping velocity — releases a month over the last 12 months, on a log scale where 16 a month scores 100. Needs 3 releases in the window.
  • Documentation quality — the release-notes rubric published on the analytics page, unchanged.
  • Breaking-change discipline — the share of releases carrying a breaking change (none scores 100, half or more scores 0). Only projects that label breaking changes are measured: a clean record cannot be told from an unlabelled one.
  • Maintenance risk — quiet time measured against the tool's own release cadence (quiet longer than 90 days and three typical gaps scores 0), plus the number of active maintainers and whether contributors are growing, where known. Higher is lower risk.
  • Innovation & surface — new capabilities in the feature ledger this year, API and MCP operations added, and the share of commits that are features: the mean of whichever we hold.
  • Community health (open-source tools only) — each is a direction, not a size: contributors this year against last, the bus factor now against a year ago, and issues closed per issue opened, where steady scores 50, doubled 100 and halved 0; plus the median time to a maintainer's first reply (an hour scores about 100, a month or more 0). A commercial card has no repository and carries none of the four.
  • Documented delivery (commercial tools) — when a vendor's documented new capabilities have slowed against its own baseline, that counts against the overall standing as heavily as two low dimensions. Steady delivery, or too little history to judge, leaves the standing alone; it is never a sixth score.
  • Open-source tools are scored on repository signals; commercial tools on their published changelog. Ranks compare tools within one category and one profile and need at least five measured peers; the overall standing needs three ranked dimensions. Best-in-breed or consolidator is a shape, not a quality, and is never scored.
