Mastra

CrewAI LangGraph OpenAI Agents SDK Langflow Botpress Gumloop Lindy Microsoft Copilot Studio

Mastra in brief

TypeScript framework for AI-powered applications and agents, with a local Studio.

@mastra/core 1.79.0 adds experimental MCP Events, richer observability (span aggregation and time-to-first-chunk), session-ID based agent controller sessions (a breaking change) and a native filesystem API for sandboxes.

What it does well: TypeScript-native; Detailed release notes with highlights; Strong observability additions in this release.

Where it falls short: Breaking change to agent controller sessions in this release; License reported as NOASSERTION on GitHub, so check the repository's license text; Some features are experimental; Our test was one small task on a local 3B model; it does not show behaviour with hosted models or larger jobs.

Latest version we cover: @mastra/core@1.79.0 (Oct 21, 2026). Vendor: Mastra.
