Just by the nature of what they are for (asynchronous messaging, event sourcing, and data persistence), the “Critter Stack” tools have to be considered a mission critical part of your technical infrastructure. You can pick these tools off the shelf knowing that there is a company and community behind the tools even though they’re free to use through the permissive MIT license. To that point, a support plan from JasperFx Software gives you the piece of mind to use these tools knowing that you have ready access to the technical experts for questions or to have any problems you encounter with the tools addressed.

The support contracts include a dedicated, private Discord or Slack room for your company for relatively quick response (our SLA is 24 hours, but we generally answer much faster than that). We aren’t just there for defects, we’re (JasperFx) also there to answer questions and to advise you on best usages of the tools as you need within the bounds of the contract. I’ve frequently jumped on Zoom or Teams calls with our customers for trickier questions or just when it takes more communication to really get to a solution for our customers. I can proudly say that every single JasperFx support customer has renewed their yearly support plan when the first year was up so far.

Just to give you an idea of what kind of issues JasperFx can help you with, the most common issues have been:

• Concurrency, concurrency, concurrency. Sometimes it’s helping users design queueing and messaging topologies to ameliorate concurrent access, sometimes it’s helping them to leverage Marten’s optimistic and pessimistic locking support, and sometimes it’s helping to design Wolverine resiliency strategies.
• Guidance on Event Sourcing usage within the Critter Stack, with designing event projections being a particularly common source of questions
• Multi-tenancy usage. Marten and Wolverine both have unusually strong support for multi-tenancy scenarios as a result of our users coming up with more and more scenarios for us!
• Automated testing, both how to leverage Wolverine capabilities to write more easily testable business logic code and how to use both Marten and Wolverine’s built in support for integration testing
• Plenty of issues around messaging brokers and messaging patterns
