Mastra: Free vs Paid — Is the Free Plan Enough?

⚡ Quick Verdict

Frequently Asked Questions

Why choose Mastra over LangChain.js?

Mastra is TypeScript-native with better type safety and developer experience — LangChain.js is a port from Python. Mastra's graph-based workflow engine, Zod-typed tools, and MCP authoring are more integrated. LangChain has a larger ecosystem of pre-built integrations.

Can I deploy Mastra agents to serverless platforms?

Yes. Mastra agents deploy to Vercel, Cloudflare Workers, AWS Lambda, and any Node.js hosting environment. The cloud platform adds GitHub-based automatic deployments with rollbacks and autoscaling.

Does Mastra support MCP?

Yes. Mastra includes full MCP server authoring, letting you expose agents, tools, and structured resources as MCP servers that work with Claude Desktop and other MCP clients.

What vector databases does Mastra support?

Mastra integrates with Pinecone, pgvector, and other vector stores for RAG applications. The framework uses a pluggable architecture, so additional providers can be added.

Is Mastra free?

The core framework is free and open-source under Apache 2.0. Mastra Platform (cloud hosting, observability, team features) will have separate pricing launching Q1 2026. Custom support and on-prem deployments are available via sales.
