Shmastra Cloud

Shmastra for your whole team. Each colleague signs in through WorkOS and gets a private E2B sandbox with Mastra Studio and Shmastra already running — no local setup needed.

Ready to deploy on Vercel.

Environment variables

Add these to Vercel → Settings → Environment Variables (or fill in during deploy):

Variable	Description
WORKOS_API_KEY	WorkOS API key (sk_...)
WORKOS_CLIENT_ID	WorkOS client ID (client_...)
WORKOS_ORGANIZATION_ID	WorkOS organization ID (org_...)
WORKOS_COOKIE_PASSWORD	Random string, min 32 chars
E2B_API_KEY	E2B API key
SUPABASE_URL	Supabase project URL
SUPABASE_SERVICE_ROLE_KEY	Supabase service role key
OPENAI_API_KEY	OpenAI API key
ANTHROPIC_API_KEY	Anthropic API key
GOOGLE_GENERATIVE_AI_API_KEY	Google Generative AI key
COMPOSIO_API_KEY	Composio API key

One-time before production

1. Run supabase/migrations/001_init.sql in the Supabase SQL Editor.
2. Build the E2B template locally with npm run template:build (requires E2B_API_KEY) whenever you change the image or Mastra repo in the script.

Local

npm ci
cp .env.example .env.local
npm run dev

Production build (same as Vercel): npm run build (build:studio + next build). Routes that use E2B must stay on the Node runtime—do not move them to Edge.

Sandbox Manager

Admin tool for managing all user sandboxes — update code, chat with an AI agent, browse files, and view logs. Run with npx tsx manage/index.mts --serve. Full reference →

Healer Agent

Each sandbox runs a self-healing PM2 process that monitors server health and automatically diagnoses and fixes crashes via a Claude-powered agent. How it works →
