Could you build this?

Partial Generating code with an LLM is straightforward, but orchestrating isolated cloud sandboxes with full Linux environments, virtual displays, and self-healing agent loops requires complex infra.

What it would actually take: The architecture requires multi-tenant container orchestration (e.g., via Docker, Firecracker microVMs, or WebContainers) capable of running dev servers, headless browsers (Playwright/Puppeteer), and mobile simulators securely in the cloud. The agent loop must execute shell commands, parse build and runtime errors, and iteratively patch source trees while streaming visual previews to the client in real time.
