Support Subscriptions

The Standard and Premium Enterprise Support subscriptions are sold as annual subscriptions with options that start at 2,250 EUR for 5 devices. The Standard subscription provides support suitable for all commercial Syncthing users, where longer service level agreements (SLAs) are acceptable and hot fixes for production deployments are not required. The Premium subscription is suitable whenever priority case handling is required. It includes faster response times, expedited solutions, phone support for critical production issues, and access to custom feature development.

Frequently Asked Questions

Which versions of Syncthing are supported?
We advise users to run the most recent version of Syncthing, as it is the most up to date and secure. We proactively notify all subscribers when updates are available. We provide technical support for the current release, and any release issued within one year of the current release.
How do I create a support ticket?
To create a support ticket, please use the email addresses in your support contract to send and receive support case information. You can also use the support portal to create and follow up on support tickets. If you have a Premium support subscription, you can get support by phone for critical issues.
What SLA can Kastelo guarantee?
For Premium support customers, Kastelo guarantees an SLA of two hours for the initial contact in new support queries. We will offer service credits in the event that we fail to meet this expectation.
How is the open source Syncthing supported?
Kastelo supports binary builds of the open source Syncthing that are obtained from the official GitHub releases page and the Syncthing APT repository (apt.syncthing.net). Purchase a Standard or Premium support subscription for each Syncthing device that requires support. Kastelo does not support binaries that you build from source yourself, or binary distributions obtained from other sources.
What happens when my support expires?
After your support contract expires you are no longer eligible to obtain support from Kastelo. Access to the Kastelo support portal will be revoked. However, your ability to continue to use Syncthing is not affected in any way.
How many of my devices do I need to have under support?
Each Syncthing device used as part of the deployment where support is required must be covered by the support subscription. Support may be withheld if it is discovered that a significant part of the deployment is not covered by the subscription. There may be other deployments, used for a different purpose, which are not covered by support.
How can I get design or consultancy help?
If you need help with architecture, design, or configuration, we can help you translate your requirements into an optimized Syncthing deployment. Please contact us to learn more.
