Technical Use Cases
Mastra is well-suited for TypeScript engineering teams building any of the following:
- Long-running autonomous agents — workflows that span hours or days, requiring durable execution and reliable state management
- Multi-step AI pipelines — typed workflow graphs with branching logic, retries, and conditional control flow
- RAG and memory-augmented agents — agents that use semantic recall to retrieve relevant context from past interactions or external knowledge bases
- Multi-model applications — systems that route between OpenAI, Anthropic, Google, xAI, or other providers based on task, cost, or latency requirements
- DevOps and incident automation — integrations with Jira, GitLab, and incident.io make Mastra a natural fit for agents that triage issues, open tickets, or coordinate incident response
- Observed, evaluated agent systems — teams that need evals, trace data, and datasets to continuously measure and improve agent quality in production
- Self-hosted AI infrastructure — organizations with strict data residency or compliance requirements can deploy Mastra under Apache 2.0 on their own infrastructure
