License & Plugin Compatibility
How Licenses Work
When you purchase a Kirby Tools plugin, you receive a license key that covers specific plugin versions. Your license generation determines which versions you can use:
- Generation 1 (purchased before December 2024): Covers original plugin versions
- Generation 2 (purchased from December 2024): Covers original + Kirby 5 compatible versions
You can always use older plugin versions with newer licenses, but not newer plugin versions with older licenses.
Quick Reference
- All plugins support both Kirby 4 and Kirby 5
- Upgrade discount: Gen 1 license holders get 50% off when upgrading
- Manage your licenses at hub.kirby.tools
Updates vs Upgrades
Updates (Free)
Bug fixes, security patches, and minor improvements within your licensed versions. These are always free and automatic via Composer.
Upgrades (Paid/Discounted)
Moving to a new major plugin version that adds significant features or Kirby compatibility. Upgrades typically coincide with new Kirby releases.
Why the distinction? Major Kirby releases often require significant plugin rewrites. The upgrade model lets us continue development while offering existing customers generous discounts.

Frequently Asked Questions
Not necessarily. If you have a Generation 2 license (purchased December 2024+), it already covers Kirby 5 versions. Check your license at hub.kirby.tools.
License generation (Gen 1, Gen 2) determines which plugin versions your license covers. Plugin version (v1, v2, v3) is the actual version you install.
SEO Audit v3 is primarily a Kirby 5 compatibility update. Content Translator v3 introduces significant new features, which is why upgrade pricing applies (50% off).
Yes. Licenses are backward compatible – you can always use older versions.
