patchletter vs. NewReleases.io
NewReleases.io is a free release tracker for developers and DevOps: it watches Git forges (GitHub, GitLab, Codeberg …), package registries (npm, PyPI, Maven, Cargo …) and container registries and notifies you about new versions — via email, Slack, Telegram, Discord, Teams, webhooks and more.
patchletter takes a different angle: a free update radar for sysadmins that combines vendor release tracking, actively exploited vulnerabilities (CISA KEV) and end-of-life dates — delivered as one quiet email digest instead of a real-time firehose.
Side by side
| Feature | patchletter | NewReleases.io |
|---|---|---|
| Release tracking for vendor products (Proxmox, FortiOS, Veeam …) | ✓ curated vendor sources: APIs, feeds, release-notes pages | partly forges/registries only — no vendor websites (no Proxmox, FortiOS or Veeam advisory tracking) |
| Actively exploited vulnerabilities (CISA KEV) | ✓ curated & low-noise — only demonstrably exploited CVEs | ✗ |
| End-of-life / support dates | ✓ endoflife.date data on every product page | ✗ |
| Hardware / firmware (firewalls, NAS, switches) | ✓ | ✗ |
| Email instantly / daily / weekly | ✓ | ✓ |
| Slack / Teams / webhooks | ✗ on the roadmap — patchletter is email-first | ✓ |
| API | partly RSS feed per product; API on the roadmap | ✓ |
| Free to use | ✓ completely free, no limits | ✓ free, donation-supported |
When NewReleases.io is the better choice
- Lots of integrations: Slack, Teams, Telegram, Discord, Matrix, webhooks and an API — patchletter is email-first (for now).
- Deep coverage of developer sources: npm, PyPI, Docker Hub & co., including regex version filters and pre-release exclusion.
- Dependency-file import to watch projects automatically.
Nothing wrong with running both: NewReleases.io for its strengths, patchletter for the vendor gear it can’t see.
