Another busy week at Mastra. We're thrilled to announce the public beta of Mastra Cloud, plus some exciting new features that make building AI agents and workflows even more powerful.
Let's dive into this week's updates.
Mastra Cloud
We're opening up Mastra Cloud to everyone—no waitlist, no invite, just head to mastra.ai/cloud and start building.
With Mastra Cloud, you can:
- Deploy and manage agents, workflows, MCP servers, and tools.
- Test in playground
- Monitor, observe, and debug your runs in real time.
Sign up and deploy your first agent in minutes at mastra.ai/cloud.
Agent Network
You can now chat with your agent network in playground — great for complex tasks like "research London AND write an article about its weather".
We currently have two chat modes: loop and stream.
Loop lets your agent network keep iterating for a specified number of execution steps. You can tweak the max iterations directly in Playground.
Memory
Last week we added per-resource semantic recall. This week, we added per-resource working memory across multiple Mastra packages.
This enables persistent user memory across multiple conversation threads. We've also included flexible scoping options.
Workflows
We added a new bail function to workflows. This method allows workflows to exit a step early.
It also updates the return types of suspend() and bail() to any so that their value can still be returned (without having to return something that looks like the step result type).
We also introduced a new async operation createRunAsync() that also stores a pending workflow state into storage. As such, the createRun method is deprecated and will logger.warn().
Mastra 101
We added a new lesson to Mastra 101, our mcp-based course that you can take directly in your IDE (like Cursor or Windsurf).
This fourth lesson teaches you how to build powerful workflows that orchestrate multiple AI agents and tools.
That's it for this week! As always, we'd love to hear your feedback and see what you're building with Mastra.
Happy building! And remember: you can just deploy things. 🚀
