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. We follow the vendors' own release sources, pull in the demonstrably exploited flaws from CISA's KEV catalogue and record the end-of-support dates from endoflife.date. Whether you hear about it instantly, once a day or once a week is yours to set. The update radar costs nothing.
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; free to read, alert email with Pro | ✗ |
| End-of-life / support dates | ✓ endoflife.date data on every product page; warning email 90/30/7 days ahead with Pro | ✗ |
| Hardware / firmware (firewalls, NAS, switches) | ✓ | ✗ |
| Email instantly / daily / weekly | ✓ | ✓ |
| Slack / Teams / webhooks | partly Slack, Teams, webhook with Pro | ✓ |
| API | ✓ read-only REST API v1, free and without an account; plus an RSS feed per product | ✓ |
| Free to use | partly update emails free; security and EOL alerts with Pro | ✓ free, donation-supported |
When NewReleases.io is the better choice
- Lots of integrations: Slack, Teams, Telegram, Discord, Matrix and webhooks — more targets than patchletter offers with Pro (Slack, Teams, webhook).
- 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.
Tick off what you run
Confirm your address once, and after that an email arrives as soon as one of your vendors ships a new version. That is all we need.
