Mastra v1.0 GA: TypeScript Agent Framework Reaches 220K Weekly NPM Downloads with SoftBank, Adobe, and Replit Agent 3 in Production
Mastra cut its v1.0 release marking API stability for agents, workflows, evals, and observability after shipping incrementally through v0.21–0.23. The release formalizes agent.network(), Mastra Auth, and multi-engine workflow support (Inngest). At 220K weekly downloads and production adoption by SoftBank, Marsh McLennan, Adobe, and Replit Agent 3, Mastra is now the dominant TypeScript-native agent framework — significant for the large cohort of Next.js developers who need a production-grade TypeScript-first alternative to Python-centric frameworks like LangChain.
