Vibe-code AI agents and workflows right inside Mastra Studio — no IDE, no config, just chat.
Mastra is brilliant — if you write TypeScript. Shmastra brings that power to everyone.
npx create-mastra@latest --template https://github.com/just-ai/shmastraThen just follow the on-screen instructions.
I always wanted to build multi-agent systems and workflows by simply describing what I need in a chat. Let the assistant find the right APIs, hook up MCP servers, connect Google Drive and whatever else — all in one click.
Mastra already lets developers do this in TypeScript with Claude Code. But even for engineers, wiring everything together is a grind.
Shmastra lets anyone — engineers or not — vibe-code agents and entire workflows directly in Mastra Studio. No context-switching, no boilerplate, no setup.
- 💬 In-browser vibe agent — build agents and workflows without leaving Mastra Studio
- ♻️ Self-healing builds — creates agents & workflows, rebuilds and hot-reloads changes automatically
- 🔍 Inspect & fix — navigate to any agent or workflow page and ask Shmastra to debug it
- 🔌 Auto-discover integrations — searches and connects MCP servers or third-party services to your agents and workflows on the fly
- 🔑 One-click OAuth — authorizes you with any external service that requires OAuth
- 📁 First-class file handling — no base64 hacks; files are saved to disk with temporary public URLs generated when running on localhost
- 🧠 Built-in RAG + browser — agents get markitdown-powered RAG, a Playwright browser, and automatic web search via your chosen LLM provider
- 🖼️ Rich chat extras — renders iframes for generated HTML, perfect for interactive charts, dashboards, or landing pages your agent creates
