patchletter
Know the moment your stack gets an update.
Free update radar for sysadmins: check off the software and hardware you run — browsers, hypervisors, firewalls, NAS, line-of-business apps — and get one email the moment an update ships. 727 products, checked daily against official vendor release sources. Plus end-of-life dates and actively exploited CVEs (CISA KEV) per product. No account, no tracking, no ads — and it runs on our own server in Germany. Free.
I run IT for a living, and the thing that kept biting me was never the patching itself — it was finding out an update existed. Vendor release pages, RSS feeds that die quietly, newsletters I stopped reading.
So patchletter does one thing: you tick off the software and hardware you actually run — Proxmox, FortiOS, Synology, Veeam, whatever — and you get one email when something ships. No agent, no scanner, no account. We check 727 products daily against the vendors' own release sources.
Two things I added because I needed them myself: end-of-life dates per product, and a flag when a CVE in your stack shows up on CISA's actively-exploited list.
It's free, ad-free, and there is no tracking — no pixel and no rewritten links in the emails either. Runs on our own server in Germany.
I'd love to know: which tool is missing from the catalogue for you? That's the fastest way to make this useful — suggestions with votes get added first, usually within a week.
