Mastra vs SmartBear
Side-by-side comparison of AI visibility scores, market position, and capabilities
Open-source TypeScript AI agent framework from ex-Gatsby team. 22K+ GitHub stars, 300K weekly npm downloads; used by Replit, Marsh McLennan, and SoftBank.
About
Mastra is an open-source TypeScript framework for building AI agents and agentic workflows, created by the team that previously built Gatsby, the widely adopted React-based web framework. The project was founded on the insight that the emerging ecosystem of AI agents lacks the kind of opinionated, developer-friendly framework that accelerated the adoption of modern web development — tools that provide sensible defaults, strong conventions, and a productive development experience out of the box. Mastra fills that gap for TypeScript developers building production AI systems.\n\nThe framework provides abstractions for the core primitives of agentic AI: tool use, memory and state management, multi-agent orchestration, workflow automation, and LLM integration. Rather than requiring developers to assemble these capabilities from raw API calls and bespoke glue code, Mastra provides a unified framework with TypeScript-native types, built-in observability, and integration with popular AI providers. Its architecture is designed for production deployments — handling the reliability, debugging, and operational monitoring requirements that experimental agent prototypes typically lack.\n\nMastra has achieved rapid adoption since launch: 22,000+ GitHub stars and 300,000 weekly npm downloads signal strong developer enthusiasm, and its production adoption by companies including Replit, Marsh McLennan, and SoftBank portfolio companies demonstrates that it is being used for real enterprise workloads, not just side projects. The Gatsby team's previous success in building a widely adopted developer framework gives Mastra credibility in the developer tools market — they have built popular open-source infrastructure before and understand what it takes to grow and maintain a developer community. As agentic AI moves from experimentation to production, Mastra is positioned to become foundational infrastructure for TypeScript AI development.
