About Mastra
Mastra is a TypeScript framework for building AI agents and the workflows around them. It bundles agents, tools, memory and a local development server in one toolkit.
What it does
You define an agent with instructions, a model and a set of tools, then wire it into multi-step workflows. Memory lets conversations carry context forward. Tracing, metrics and evaluation tools show what an agent did and how well it did it, and agents can be served over a local server for use in other apps.
Key features
- Agents with instructions and tools

Who it's for

Pricing and good to know
