EnglishWhat is Xeol and what does it do?
Updated
Xeol is a tool for securing how you use open source: it identifies and fixes end-of-life (EOL), outdated, and unmaintained dependencies in your software. According to its documentation hub at docs.xeol.io, the name is pronounced "Zee-O-L" — like EOL (end-of-life) with a Z in front. The site is the entry point to Xeol's documentation, so it explains the product's purpose rather than listing installation steps or feature-level instructions.
The problem Xeol addresses
The core mechanism is straightforward: software that its publisher no longer supports stops receiving security fixes. Xeol's documentation defines EOL software as software "no longer supported by their publishers and thus no longer receives any security fixes," and notes that outdated and unmaintained dependencies generally fall into the same category.
That matters because a dependency can keep working in your build while quietly accumulating unfixed vulnerabilities. For example, a library that was last updated years ago may still install and run fine, but any vulnerability disclosed after its final release will never be patched by its maintainer. Xeol's stated job is to surface those dependencies and help you fix them.
What the documentation covers
The docs.xeol.io home page is organized around a documentation index and two introductory sections:
| Section | What it answers |
|---|---|
| What is Xeol? | The product's purpose: identifying and fixing EOL, outdated, and unmaintained dependencies |
| Who are we? | Background on the founding team |
| Documentation Index | The entry point to the rest of the docs |
The page itself does not publish pricing, plan details, or setup instructions. If you need those, they would live elsewhere in the documentation index rather than on the landing page.
Who is behind it
The documentation describes Xeol as the work of two technical founders who met during the founding stages of an AI company and have worked together for five years. Their stated background includes leading security, backend, DevOps, and SRE teams. The page lists a contact address, [email protected], for anyone who wants to talk to them directly, along with links to GitHub, LinkedIn, Twitter, and the company website.
When Xeol is relevant to you
Xeol is worth looking into if you maintain a codebase with many open source dependencies and need a way to spot ones that are no longer maintained or supported. It is less relevant if you are looking for a general-purpose vulnerability scanner description or a pricing comparison — the documentation hub does not provide those on its home page. The practical next step is to browse the Documentation Index at docs.xeol.io to see what workflows and integrations are documented.
