Blaxel Agents Hosting lets you bring your agent code and deploys it as a serverless auto-scalable endpoint — no matter your development framework. Follow these steps to get your AI agent up and running on Blaxel.

​
1. Create configuration files

At the root of your project repository, create a blaxel.toml file for configuration, and a .env file for your sensitive environment variables. Example blaxel.toml: 
type = "agent"

[runtime]
generation = "mk3"
memory = 4096

[env]
MY_NON_SENSITIVE_ENV = "MY_NON_SENSITIVE_ENV"

​
2. Update host and port in your code

Ensure your app listens on the host and port provided by Blaxel. Update your code accordingly: 
const port = parseInt(process.env.BL_SERVER_PORT || "80");
const host = process.env.BL_SERVER_HOST || "0.0.0.0";

​
3. Deploy your agent

When deploying, there are two possible scenarios:

​
Option A: You already have a Dockerfile

Blaxel will automatically use it to build your agent. Just run: 
bl deploy

​
Option B: No Dockerfile

If you don’t want to create one, add the following scripts to your package.json. Depending of what you do, all of the scripts are not required. With TypeScript, all 4 of them are used.
  • start : start the server locally through the TypeScript command, to avoid having to build the project when developing.
  • build : build the project. It is done automatically when deploying.
  • prod : start the server remotely from the dist folder, the project needs to be have been built before.
  • dev : same as start, but with hotreload. It’s useful when developing locally, each file change is reflected immediately.
The remaining fields in package.json follow standard JavaScript/TypeScript project conventions. Feel free to add any dependencies you need, but keep in mind that devDependencies are only used during the build process and are removed afterwards. 
{
  "name": "name",
  "version": "1.0.0",
  "description": "<no value>",
  "keywords": [],
  "license": "MIT",
  "author": "cdrappier",
  "scripts": {
    "start": "tsx src/index.ts",
    "prod": "node dist/index.js",
    "dev": "tsx watch src/index.ts",
    "build": "tsc"
  },
  "dependencies": {
    "@ai-sdk/openai": "^1.2.5",
    "@blaxel/sdk": "0.1.1-preview.9",
    "ai": "^4.1.61",
    "fastify": "^5.2.1",
    "zod": "^3.24.2"
  },
  "devDependencies": {
    "@types/express": "^5.0.1",
    "@types/node": "^22.13.11",
    "tsx": "^4.19.3",
    "typescript": "^5.8.2"
  }
}
Then run: 
bl deploy

​
4. (Optional) Enable telemetry

Instrumentation happens automatically when workloads run on Blaxel. To enable telemetry, simply import the SDK in your project’s entry point. For TypeScript: 
import "@blaxel/telemetry";
For Python: 
import blaxel.core

​
5. (Optional) Run locally with Blaxel CLI

If you want to run your agent locally and start using the SDK, make sure the start and dev scripts are defined, then run: 
bl serve
# or
bl serve --hotreload
That’s it! You’re ready to start integrating Blaxel features using the Blaxel SDK.
