# Introduction
StartSharp is premium version of our free Serene application template.
It includes everything that Serene has, in addition to extra samples, features, integrations and modules.
Premium Packages
Our premium packages that include StartSharp template are available at http://serenity.is.
Currently, four levels are offered: Basic, Personal, Professional and Enterprise.
They also contain varying levels of premium support, except Basic level which doesn't include support.
Let's first explain what you get with these premium packages.
Commercial Licence
Serene Template and Serenity itself has a permissive MIT licence which allows usage in open source, commercial and proprietary applications.
StartSharp, which is also based on Serenity, comes with a commercial licence, that allows you to use it with any number of commercial applications / sites (except Basic level which allows only one application)
You are not allowed to use StartSharp content in an open source application as it would mean open sourcing StartSharp itself.
StartSharp is licenced per seat / developer.
Basic and Personal levels comes with one licence, and allows just one developer to use StartSharp. These levels are only suitable for single / freelance developers.
You are allowed to use Basic level licence for only one application / project. If you are planning to write multiple applications, you should consider Personal or higher levels.
Professional level comes with 3 seats / developers licences, while Enterprise contains 5 seats / developers licences.
Even though it is possible to buy multiple Personal licences, we recommend Professional or Enterprise as they are more cost effective.
We also offer volume licencing discounts. Contact us at [email protected] for more information.
Private Support Desk
You get prioritized e-mail support from our core developers, with guaranteed initial response time of 72 / 48 / 24 hours (excluding weekends and public holidays) based on your support level.
Basic level doesn't contain any support.
This guranteed response time is for a certain number of issues (as a fair use policy) based on support level:
- Personal: 72 hours for first 10 Incidents
- Professional: 48 hours for first 15 Incidents
- Enterprise: 24 hours for first 20 Incidents
This doesn't mean you won't receive an answer to your further incidents, response is just not guaranteed within specified time.
Initial response time specified excludes weekends and public holidays.
Live Credits
These are hours that you can use to get direct remote support from our developers.
We recommend using these credits for troubleshooting, so that you can save your precious hours / days by letting us handle the problem in a few minutes.
You may also use these hours for custom development, additional features etc.
It's also possible to buy additional hours, and our premium members get a discount over average fee.
Basic and Personal doesn't contain any live credits.
Professional level comes with 3 hours of live credits, while Enterprise has 5 hours.
Access to Full Source Code
All levels except Basic, provides access to StartSharp GitHub repository with full source code.
Expiration and Renewals
The packages you buy provide access to StartSharp repository, updates and premium support for a period of 12 months (except Basic).
Once that period ends, we won't auto renew your subscription and you'll receive an e-mail from us with a discounted renewal offer (usually around 25%).
If you choose to not renew, you'll only lose access to StartSharp source code, updates and premium support.
You'll be keeping your StartSharp licence and continue using versions of StartSharp released during your subscription period.
Your existing projects will continue to work, and you can still create new projects using your version of StartSharp.
