What is Semgrep?
Semgrep is a fast, open-source-rooted static analysis tool that helps developers and security teams find bugs, security vulnerabilities and code-quality issues across their codebases — and enforce their own standards — without the slowness and noise that plague traditional SAST tools. Its name hints at its approach: "semantic grep," a way to search code for patterns based on its structure and meaning, not just text, making it both powerful and approachable for developers.
The key to Semgrep's popularity is that it's genuinely developer-friendly. Writing custom rules is intuitive — they look much like the code you're trying to match — so teams can codify their own best practices, catch specific anti-patterns, and prevent classes of bugs from recurring, all without becoming static-analysis experts. It ships with a large library of community and curated rules covering common security vulnerabilities across many languages and frameworks, so you get value immediately, and it runs fast enough to fit into local development and CI pipelines without grinding things to a halt.
For security teams, Semgrep provides a scalable way to embed security checks directly into the development workflow, catching issues early — when they're cheapest to fix — rather than late in a heavyweight audit. It can scan code, dependencies and secrets, integrate with CI/CD and code hosts, and give teams a clear, low-noise stream of actionable findings. This shift-left, developer-centric philosophy has made Semgrep a favorite among engineering and AppSec teams that want effective security and code governance without alienating developers with slow, false-positive-ridden tools. For organizations that want to find vulnerabilities, enforce standards and improve code quality in a way developers will actually adopt, Semgrep offers a fast, flexible and pragmatic solution that has earned its strong reputation in the security community.
What is Vulnerability Tools?
Vulnerability Tools is a free website vulnerability scanner that gives any site owner a clear, honest picture of their website's security in minutes. Most small businesses and bloggers know they should check their site for weaknesses, but professional security audits are expensive and technical reports are hard to read. Vulnerability Tools closes that gap: enter a website address, run a scan, and get one clear report that explains what was found and what to fix first. There is no signup and no software to install.
The scanner checks for known vulnerabilities in the software a site runs on, including outdated content management systems, plugins and themes. It looks for malware and suspicious code, reviews security headers such as content security policy and strict transport security, and flags misconfigurations that attackers commonly exploit. Alongside the security checks, it audits on-page SEO and page speed, because a slow, poorly optimised site is easy to overlook and hard to trust. The result is a single report that covers security, SEO and performance together, with each finding explained in plain language.
WordPress sites get dedicated attention. The free WordPress vulnerability scanner checks installed plugins and themes against known vulnerability databases, so owners can spot the outdated component that puts their whole site at risk and update it before it is exploited. The wider toolkit covers everyday checks that site owners need again and again: a domain expiry checker, an HTTP status code checker, an SEO audit tool, and more, all free to use without an account.
Vulnerability Tools is built for website owners, bloggers, freelancers, agencies and small teams who want to keep their sites safe without hiring a security consultant. It is also useful for developers who want a quick second opinion before launching a site, and for anyone who has inherited a website and needs to know what state it is in. The reports are written for people, not just engineers: every issue comes with a plain explanation and a practical next step, so owners can fix the important things first and track improvements over time.
Security is not a one-time job. New vulnerabilities appear every week, plugins go out of date, and settings drift. A free scanner that anyone can run as often as needed makes regular checking realistic. Run a scan after every update, before a launch, or whenever something on the site changes, and fix what matters first.
What problem it solves
Small website owners cannot tell whether their site is vulnerable, and professional security audits are too costly and too technical — so weaknesses go unchecked until a site is hacked.
