MCP SUPPORTED
Latest: v1.41.2
// Our Verdict
The strongest choice for enterprise teams in Microsoft-stack environments. Its breadth of language support and deep Azure integration give it a moat in enterprise AI deployments.
Best for: Enterprise teams building copilots and agents on Azure or within Microsoft-stack environments
// Strengths
Broadest language SDK coverage: Python, C#, and Java all maintained
Deep Azure OpenAI and Microsoft 365 integration
Process framework for durable, stateful multi-step agent workflows
Mature plug-in architecture with built-in memory abstractions
MCP support via plug-in layer
// Weaknesses
Significant learning curve — the abstraction surface is large
Observability gaps: the plugin/kernel architecture creates a 'black magic' feeling; tracing internal state requires additional tooling compared to lighter frameworks
C# / .NET is by far the most polished SDK; Python and Java versions receive new features later and have rougher edges
Microsoft-ecosystem alignment creates friction for non-Azure deployments
Documentation quality varies notably across language SDKs
Slower community iteration than Python-native frameworks

NOT SURE IF SEMANTIC KERNEL
FITS YOUR STACK?
FITS YOUR STACK?
We map your agent system requirements, evaluate which framework fits your constraints, and give you a prioritised build plan. No fluff. Just a clear stack decision with rationale.
