Mastra
A TypeScript framework for building and operating AI agents, workflows, memory, tools, and observability.
About Mastra
Mastra is a TypeScript framework for building AI applications and agents with typed definitions for models, tools, instructions, memory, and runtime behavior. It also supports durable multi-step workflows and includes observability for logs, metrics, and traces. Developers can start a project with the create Mastra CLI, work locally in Mastra Studio, and deploy through their own infrastructure or Mastra Platform. The open-source framework is Apache 2.0 licensed and can be hosted anywhere. Platform pricing starts with a free Starter tier, while Teams costs $250 per month and Enterprise uses custom pricing. Usage beyond included platform allowances can add charges for traces, data egress, CPU time, gateway tokens, memory, retrieval storage, and databases. Mastra is a practical fit for TypeScript teams that want one framework across agent logic and operational tooling. Buyers should estimate workload-based costs and confirm that its TypeScript-first approach fits their stack.

Features
Build typed AI agents
Define agent instructions, models, tools, memory, and runtime behavior in a TypeScript project.
Orchestrate durable workflows
Create multi-step agent processes with typed control flow for work that must continue reliably.
Operate production agents
Use Studio plus logs, metrics, and traces to test, inspect, deploy, and monitor agent applications.
Pros
- The Apache 2.0 framework costs $0 and can be hosted on infrastructure you control.
- Typed agents and durable workflows keep agent logic in the same TypeScript development workflow.
- Built-in logs, metrics, traces, Studio, and deployment tooling reduce the number of separate operational tools.
Cons
- Platform usage beyond included allowances can add charges across observability, egress, compute, tokens, storage, and databases.
- The TypeScript-first workflow is less convenient for teams standardized on Python or another runtime.
- Enterprise self-hosting features and pricing require a sales conversation, which limits upfront cost comparison.
