Lifetime Updates

When you purchase Comet Cache Pro, you receive lifetime software updates. You may continue to use Comet Cache Pro for as long as you wish.

Single-Site vs. 3-Site vs. Unlimited-Site License

Single-Site License: This allows for one instance of Comet Cache Pro. Perfect for site owners with one domain name. Loaded with all Pro features at an affordable rate. It's a popular choice for many.

Multisite Networks: Please note that if you run a WordPress® Multisite Network with Comet Cache Pro active on multiple child blogs or sub-sites within your Network (regardless of whether you use sub-domains or sub-directories), this will always require our Unlimited-Site License. This is because Comet Cache Pro runs as a separate instance on each child blog or sub-site in the Network. To clarify, a Single-Site License does NOT allow for multiple child blogs or sub-sites, even if they do run within a single Multisite Network installation of WordPress®. A Single-Site License is valid for one instance only.

3-Site License: This allows for three (3) instances of Comet Cache Pro. Perfect for site owners with up to three domain names. Loaded with all Pro features at an affordable rate. It's our most popular choice.

Unlimited-Site License: This allows for an unlimited number of Comet Cache Pro instances. Perfect for site owners with multiple domain names, and/or those who operate a WordPress® Multisite Network installation. Each of your Comet Cache Pro instances must be installed/activated on domains that you own & operate; e.g. you cannot buy an Unlimited-Site License and use it on client sites that you do not own. (To cover this scenario, see the developer section below.)

Developer License

If you're a developer: Your clients will need to purchase their own Single-Site and/or Unlimited-Site License, or you can purchase a Developer License that will cover their sites. The Single-Site and Unlimited-Site licenses do not allow Comet Cache Pro instances on domains that you do not own and operate yourself—a Developer License is required to cover sites that you do not own.

This also gives your clients access to future releases through an account they'll acquire at our website. It's the approach we suggest for all developers working w/ clients needing Comet Cache Pro, but if you're managing your clients' sites you can use a Developer License to cover that scenario.
