Consulting Services
JasperFx provides expert consulting to help your team formulate solutions, understand the impact of different architectural patterns, and apply the Critter Stack tools in the most effective way possible.
We have helped clients migrate legacy systems to modern event-driven architectures, significantly improved system performance and scalability, and guided teams in building resilient, production-ready systems. Whether you need an architectural review, hands-on guidance through a modernization effort, or deep expertise in Event Sourcing, CQRS, and asynchronous messaging — we bring decades of real-world experience to your challenges.
Every engagement starts with a discovery call to understand your needs and goals.
Support Agreements
A JasperFx support agreement gives you an ongoing relationship with the team that builds and maintains the Critter Stack. When you are building mission-critical systems on Marten, Wolverine, or related libraries, having direct access to the experts behind the tools provides invaluable peace of mind.
Support goes well beyond bug fixes — we are there to answer questions, advise on best practices, help with concurrency patterns, event sourcing design, multi-tenancy, testing strategies, and messaging configuration. Complex issues can be discussed over Zoom calls for faster resolution.
Plans include a private Discord or Slack channel, issue tracking, and guaranteed response times. New contracts begin with an onboarding meeting to understand your systems and goals.
Workshops
JasperFx offers intensive, interactive 1-2 day online workshops to get your team up to speed on the Critter Stack and the architectural patterns that make it powerful.
Workshop topics include the Critter Stack tools (Marten, Wolverine, and related libraries), common challenges with Event Sourcing, CQRS, asynchronous messaging, and automated testing strategies. Each workshop is customized to your team's needs, codebase, and goals — not a generic slide deck.
Whether you are adopting the Critter Stack for the first time or looking to deepen your team's expertise, our workshops provide focused, hands-on learning with the people who built the tools.
CritterWatch & Commercial Products
Beyond the open source Critter Stack, JasperFx is now offering commercial tools designed to make your production systems easier to manage and your development faster.
CritterWatch provides operational insight and observability for systems built on the Critter Stack — production monitoring, management, and diagnostics in one place. Our AI Skills collection and MCP Extensions are development-time accelerators that make building with the Critter Stack even more productive.
We also offer Marten extensions for PostGIS and PgVector, adding geospatial and vector search capabilities to your PostgreSQL-backed applications.
