About Mastra
Mastra supplies building blocks for AI applications in TypeScript, including agents, workflows, memory, retrieval, and evaluations. It helps developers organize behavior that would otherwise be spread across prompts and custom glue code. You can use the open-source framework and choose a deployment approach, or evaluate Mastra's cloud services with their own plans, quotas, and overages. For a first use case, define the inputs, allowed tools, expected output, and situations needing human review. Keep a small evaluation set of real tasks and inspect failures whenever you change a model, prompt, tool, or retrieval source. Mastra participated in YC Winter 2025.
Agents and workflows
Compose agent behavior and explicit multi-step workflows in TypeScript.
Memory and retrieval
Connect relevant application context and knowledge to an agent's work.
Evaluation and deployment tools
Inspect behavior with evaluation and observability tools, then choose self-managed or cloud operation.
