Best for TypeScript developers building their own agents
Mastra is an open-source TypeScript framework for agents, workflows, memory and evals, with a free cloud plan with 100K observability events. You have to write code, there is no no-code builder, and usage past each plan's allowance is billed separately.
Who Mastra is for
- Fits if you write TypeScript and want to build your own agents
- Works for teams that want to deploy agents on Vercel or Cloudflare
Who Mastra is not for
- Not for you if you want no-code, since building an agent means writing TypeScript
- Pricey if you grow, as past the allowance egress is $0.10 a GB and events $10 per 100K
- Watch out: RBAC, SSO and audit logs are Enterprise only, and the SOC 2 report starts at Team at $250
- Watch out: some repository folders (ee/) sit under a separate enterprise licence
Why Mastra gets a 2.8
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyThe framework is open source and the cloud has a free plan. Starter is $25 a workspace a month and Team $250.
- BFree plan and trialFree cloud plan: unlimited agents, users and deployments, 100K observability events and 15-day trace retention. A solo developer can live on that.
- BFeaturesAgents, workflows, memory, evals, MCP servers and deployment to many hosts. Nothing in the listing is missing for code-first agent work.
- DEase of useNo store rating, and building an agent means writing TypeScript and running it yourself.
- BPlatforms and integrationsWeb with deployment to Vercel, Netlify and Cloudflare, and Next.js, React, Hono and Express listed.

Keep Mastra, or make your own?
Keep it
To replace Mastra you would be making an AI agent, with the models and the safeguards behind it. That is not a weekend's work, with an AI app builder or without one.
It is one of the better ones too: its GPA of 2.8 is higher than 88 of the 101 other AI agents we grade. It costs $300 a year. Mastra is open source, so there is a third way: take its code and run it yourself.
What you could not
- An AI agent, with the models and the safeguards behind it.
- Connections to other products, each kept working as those products change.
- The depth: we grade its features B, which means it covers the whole job.
What this rests on. Mastra’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is Mastra?
Mastra is an open-source TypeScript framework for building AI agents and agent-powered apps, with agents, workflows, memory, a server and observability in one package. Apps run locally or on any Node.js host, and Mastra Cloud adds hosted deployment and trace storage on usage-based workspace plans.
Worth knowing
- It is a code framework, so building an agent means writing TypeScript; there is no no-code builder.
- Cloud usage past each plan's allowance is billed separately, for example $0.10 per GB of egress and $10 per 100K observability events.
- RBAC, SSO and audit logs are Enterprise only, and the SOC 2 report starts at the Team plan.
- Some directories in the repository are under a separate enterprise license (ee/), so not every file carries the main open-source terms.
Key features
- Agents
- Typed agents are defined in code with instructions, a model, tools and runtime behavior in one place.
- Workflows
- Typed steps can be chained with retries and branches into workflows that a team can inspect.
- Memory
- Agents can keep durable context through thread-aware storage, semantic recall and an observational memory option.
- Observability and evals
- Traces, metrics and logs sit alongside evaluation tools such as scorers, datasets and experiments.
- MCP servers
- Agents, tools and other resources can be exposed as Model Context Protocol servers that any MCP-capable system can call.
- Deploy anywhere
- A Mastra app runs on any Node.js host or as a standalone server, with optional deployers for Vercel, Netlify and Cloudflare, or on Mastra Cloud.
