Give /automate a task in plain English and it drives a real browser to do it: navigate a site, click through a multi-step flow, fill a form, reach a page that only renders after interaction. The result streams back in one API call. It's an API you call, not a framework you install. Browser and LLM included, nothing to host, no concurrency ceiling. Accessibility-tree automation spends 60 to 80% fewer tokens than screenshot-based agents. Built by Mozilla. Ephemeral, no training on your data.

Could you build this?
Partial A basic browser agent can be vibe-coded using Puppeteer/Playwright and multi-modal LLM tool calling, but providing an ultra-reliable, hosted headless browser cloud service that circumvents anti-bot detection and handles complex streaming interactions requires serious distributed systems engineering.
What it would actually take: The architecture involves a multi-tenant sandboxed container pool (e.g., using Firecracker microVMs or managed Kubernetes) running headless Chromium instances hooked into an agentic loop (like Playwright with vision/DOM parsers). The hard parts are resilient anti-fingerprinting / captcha bypass, ultra-low latency SSE streaming, and failure-tolerant execution loops on dynamic single-page applications. This requires deep DevOps, distributed systems, and anti-bot mitigation expertise.
