The ultimate LLM/AI application development framework in Go.

From the team behind Gatsby, Mastra is a framework for building AI-powered applications and agents with a modern TypeScript stack.

+Go-native implementation provides excellent performance, memory efficiency, and compile-time type safety compared to Python alternatives
+Comprehensive feature set including components, ADK for agents, multi-agent coordination, and human-in-the-loop capabilities in a single framework
+Seamless integration with existing Go applications and microservices architecture without introducing language barriers

-Limited to Go ecosystem, excluding teams using other languages from adopting the framework
-Smaller community and fewer third-party integrations compared to established Python frameworks like LangChain
-Fewer learning resources and examples available due to being relatively newer in the LLM framework space

•Building AI agents and chatbots within Go-based backend services and microservices architectures
•Developing enterprise LLM applications that require Go's performance characteristics and deployment simplicity
•Creating multi-agent systems with tool coordination and workflow orchestration for complex business processes
