What is Permit.io?
Permit.io is a platform for building and managing application-level permissions and authorization, giving developers the tools and infrastructure to add fine-grained access control to their products without building it all from scratch. Authorization — deciding who is allowed to do what in an application — is a complex, recurring requirement that's easy to get wrong and tedious to maintain as products and rules grow. Permit.io aims to make implementing and managing authorization much easier, with developer-friendly APIs, support for common access-control models, and even low-code tooling to manage policies.
The platform supports a range of authorization approaches — role-based, attribute-based and relationship-based access control — and provides a way to define, manage and enforce permission policies consistently across an application. It offers APIs and SDKs so developers can integrate authorization checks into their code, along with interfaces for managing roles and policies that can involve non-developers too, helping teams keep their permission logic organized and adaptable. By providing this infrastructure, Permit.io lets teams build sophisticated, maintainable authorization quickly, rather than scattering custom permission checks throughout their codebase and struggling to keep them correct.
Permit.io is used by development teams that need flexible, maintainable authorization in their applications and want to accelerate building it while keeping it manageable as requirements evolve. By abstracting the complexity of access control into a dedicated platform with the right models and tooling, it helps teams ship secure, permission-aware features faster and adapt their authorization as their product grows. As applications become more complex and security and access requirements increase, dedicated authorization platforms are increasingly valuable to development teams. For teams that want to build and manage application permissions and authorization efficiently — with developer-friendly APIs and policy management — Permit.io offers a capable, flexible and genuinely useful solution to one of software's persistent challenges.
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.
