When does your software reach end of life?
patchletter shows the support cycles of your operating systems and admin tools, with the end-of-life date and the time remaining. Reading costs nothing, and you don't need an account.

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.
Every cycle shows how long it still runs
The tool page lists the latest version and the end of support for each cycle. The status next to it counts down the days until it flips to End of Life.
A warning before support ends
The email announcing a new version is free. The warning 90, 30 and 7 days before support ends is part of patchletter Pro — bundled across every tool you picked.
Why EOL matters
Software without support no longer receives security updates. Anyone running a release line past its end of support collects vulnerabilities the vendor will no longer fix. That date is set long in advance.
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 138 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?
Yes, with patchletter Pro: an email goes out 90, 30 and 7 days before support ends, bundled across every tool you picked. The EOL date and the time remaining are on every tool page anyway — free to read, no account needed.
What does patchletter cost?
The update email announcing a new version is free, for every product and with no limit. The EOL warning by email and the vulnerability alerts are part of patchletter Pro: €49 net per month or €490 net per year. Reading the data on the site costs nothing.
