About

Mastra is a modern AI framework built on TypeScript, designed to help developers efficiently build and manage intelligent applications. It integrates core capabilities such as workflow orchestration, memory management, and streaming processing, while also providing an interactive development environment and comprehensive evaluation and tracing tools, making the development process smoother and more controllable.

Key Features

Workflow Engine: Supports visual orchestration and automated execution of complex AI tasks.
Memory Management: Offers both short-term and long-term memory mechanisms to optimize context management and interaction quality.
Streaming Processing: Handles real-time data streams, enabling dynamic responses and low-latency output.
Interactive Development Environment: Built-in tools facilitate rapid debugging, testing, and iterative development.
Evaluation and Tracing: Fully records runtime metrics, supporting performance analysis and model optimization.

Pricing & Fees

  • Pricing: The Mastra platform offers a free Starter tier, a Teams tier at $250/month, and custom-priced Enterprise plans; the core framework is open source under Apache 2.0.
  • Free tier: The Starter plan is free for everyone and includes 100K observability events, 24 CPU hours, 15 days of data retention, and unlimited users, deployments, and projects.
  • Usage-based overages: Beyond plan allowances, Starter events cost $10/100K and CPU time $0.35/hr; Teams events cost $8/100K and CPU time $0.25/hr.
