How EOL tracking works
Support cycles from endoflife.date
We track official support and EOL cycles from endoflife.date — for operating systems, databases, runtimes and network tools.
Status & countdown per tool
On each tool page you see, per cycle, the latest version, the EOL date and the time remaining — supported, ending soon or already end-of-life.
Alongside the update radar
Subscribe to a tool and get new releases by email — updates and end-of-support in one place.
Why EOL matters
Software without support no longer receives security updates. Running operating systems or services past their end-of-life risks unpatched vulnerabilities, compliance findings and outages. A look at the support cycles tells you early what to plan for.
Frequently asked questions
What does end of life (EOL) mean for software?
End of life (EOL) is the point at which a vendor stops maintaining a software or OS version — no more security updates or fixes. From then on you should move to a supported version.
Where does the EOL data come from?
The support and EOL cycles come from the open endoflife.date project and are updated daily.
Which tools are covered?
Currently around 126 tools have EOL data — including Windows, Windows Server, Ubuntu, Debian, RHEL, Proxmox VE, PostgreSQL, MySQL, PHP, Python, Node.js, FortiOS and PAN-OS. The catalogue keeps growing.
Do I get an email when a tool reaches end of life?
You can see the EOL date and time remaining on every tool page, and if you subscribe to a tool you'll get new releases by email. Proactive EOL early-warning emails are on the roadmap.
What does patchletter cost?
patchletter is free. All you need is an email address to subscribe to tools — nothing else.
