Work with web-enabled agents quickly — whether running a quick task or bootstrapping a full-stack product.

Nolita

A web-enabled agentic framework by High Dimensional Research.

Interact with the web with an AI model of your choice and build quick runners, pipe into your scripts, or scaffold full-stack applications.

Nolita uses a sandboxed, on-device Chrome instance and supports a variety of AI models, with more on the way.

Use for quick tasks

If you if you have Node.js installed, it's as easy as running

npx nolita

If you don't include information, we will prompt you for it as we go. The flags you can provide to omit these steps include the following:

• --startUrl dictates where we start the session.
• --objective specifies what we want our agent to accomplish for us.
• --agentProvider sets who is providing the LLM for the task (currently supporting anthropic and openai).
• --agentModel specifies the model in question by the provider.
• --hdrApiKey takes your HDR key for persistent memory integration, improving the performance and reliability of tasks.
• --headless specifies whether you want the browser to run in headless mode or not. We default to true, but you can set it to false to see the browser run.
• --config takes a JSON file with the previous flags, if you want to provide them. You can also specify an inventory of personal data to use for the objective, like usernames and passwords.

{
  "agentProvider": "openai", // or process.env.HDR_AGENT_PROVIDER
  "agentModel": "gpt-4", // or process.env.HDR_AGENT_MODEL
  "agentApiKey": "sk-*********", // or process.env.HDR_AGENT_API_KEY
  "inventory": [
    {  
      "value": "student", 
      "name": "Username", 
      "type": "string" 
    },
    { 
      "value": "Password123",
      "name": "Password",
      "type": "string" }
    ]
}

Use as part of your stack

npx nolita serve

Runs a local API for objective-first agentic navigation of a local Chrome instance. After starting the server, you can see the /doc folder for the expected JSON payload.

Use --port to customize the port.

Build an app

npx nolita create

Bootstraps a template application built on Express, React, TypeScript, and the core Nolita framework for making a user-facing, web-enabled, agentic product. For more information on using the template, see its documentation.

How does it work?

Nolita drives a Puppeteer installation using local Chrome and parses the accessiblity tree, preprocessing ARIA nodes to add additional accessibility information when necessary.

At the core of the framework is a state machine between Puppeteer and your model that enforces action steps with Zod.

Since we enforce types at runtime, you can also customize the typed response you get from the navigation process! For more about that, see "Specifying types."
