Mastra is a TypeScript-first agent framework and platform with agents, workflows, memory, MCP servers, observability, evals, Studio, Server and Gateway.
Mastra is a AI agent framework for builders who want a real workflow tool, not another vague AI wrapper. The clearest evidence for Mastra is: TypeScript-first agent framework; Workflows; Memory; MCP servers; Observability; Evaluations; Studio, Server, and AI Gateway. Those details matter because they describe what a team can actually wire into a repository, agent stack, automation system, or browser workflow.
Pricing should be read carefully. Current pricing: Open-source framework: Free/open source; Platform/Cloud services: pricing isn't published. Where exact limits or dollar amounts aren't published, check the vendor's site for current plans. That is especially important for procurement because usage-based credits, workflow executions, browser sessions, or tool execution meters can change the real monthly bill. A small pilot should measure the actual unit that drives cost: credits for coding, executions for integrations, traces/evals for agent platforms, or browser runtime for web automation.
