Serverless Deployment

Standalone Mastra applications can be deployed to popular serverless platforms using one of our deployer packages:

• Cloudflare
• Netlify
• Vercel

Deployers aren’t required when integrating Mastra with a framework. See Web Framework Integration for more information.

For self-hosted Node.js server deployment, see the Creating A Mastra Server guide.

Prerequisites

Before you begin, ensure you have:

• Node.js installed (version 18 or higher is recommended)
• If using a platform-specific deployer:
  • An account with your chosen platform
  • Required API keys or credentials

LibSQLStore

LibSQLStore writes to the local filesystem, which is not supported in serverless environments due to their ephemeral nature. If you’re deploying to a platform like Vercel, Netlify or Cloudflare, you must remove all usage of LibSQLStore.

Specifically, ensure you’ve removed it from both src/mastra/index.ts and src/mastra/agents/weather-agent.ts:

export const mastra = new Mastra({
  // ...
-  storage: new LibSQLStore({
-    // stores telemetry, evals, ... into memory storage, if it needs to persist, change to file:../mastra.db
-    url: ":memory:",
-  })
});

export const weatherAgent = new Agent({
  // ..
-  memory: new Memory({
-    storage: new LibSQLStore({
-      url: "file:../mastra.db" // path is relative to the .mastra/output directory
-    })
-  })
});
