Docker, Adobe & tldraw: Where Should Your Agent Run?

The discussion explores the critical architectural question of where AI coding agents should execute, presenting four distinct models: Docker advocates for secure microVM sandboxes; Helix ML proposes centralized, dedicated computing resources for each agent; Adobe demonstrates running the agent loop entirely within the browser tab; and tldraw visualizes agents collaborating as characters on an infinite canvas. The consensus highlights the trade-offs between isolation, centralized control, and environmental fidelity.

Key takeaways

  1. MicroVMs for Agent Sandboxes 0:09

    Docker recommends using micro VMs instead of traditional containers for agent sandboxes because enterprise security teams view shared kernels as an unacceptable isolation boundary.

  2. Centralized Agent Infrastructure 3:03

    Helix ML argues for giving every agent its own dedicated computer on centralized infrastructure (e.g., Kubernetes) to facilitate seamless handoffs of work across global time zones.

  3. Browser-Native Agent Loops 7:33

    Adobe demonstrated an agent that runs its entire loop and controls the browser from within the browser tab, showcasing the concept of the 'self-licking ice cream cone' (SLICC).

  4. Collaborative Canvas Agents 6:13

    tldraw presents agents as interactive characters on a canvas that can coordinate, plan, and execute tasks as a team, allowing for simultaneous, visible collaboration.

Create an agent that can browse the web with Managed Deep Agents and Browserbase's Stagehand

This video demonstrates building a production-ready web browsing agent by integrating Managed Deep Agents (LangSmith) with Stagehand v4 and BrowserStack. The resulting agent can interact with live websites—performing actions like scrolling, clicking, and navigating—using specialized tools exposed by Stagehand to connect the AI model to scalable browser infrastructure.

Key takeaways

  1. Agent Architecture Overview

    The solution uses Managed Deep Agents as the core agent harness (LangSmith), which is augmented with tools from Stagehand v4. Stagehand, in turn, connects to web browsing infrastructure provided by BrowserStack for production-grade scalability.

  2. Stagehand V4 Tools 3:57

    The agent is given three core tools from Stagehand: `screenshot` (visually inspects the rendered page), `snapshot` (inspects the active page and hydrates element IDs for simple interactions), and `run` (accepts snapshot actions or JavaScript via the Playwright-shaped page API, ideal for multi-step workflows).

  3. Development Workflow (Local vs. Production) 6:00

    The development process involves running `mda dev` locally to test the agent in a managed deep agent studio environment. For production, the deployment is finalized using `mda deploy`, which creates a serverless deployment within LangSmith's Context Hub.
