The Paid Browser Automation Market BrowserBase, Browserless, and similar services charge per-minute or per-session for managed headless browsers. For AI workflows that need to interact with web pages (filling forms, extracting structured data, navigating multi-step processes), these services handle the infrastructure: browser instances, anti-detection, proxies, and session management. The pricing adds up fast. At $0.10-0.50 per session-minute, a workflow that processes 1,000 pages per day at 2 minutes each costs $200-1,000 per day. For an AI system that runs continuously, that's $6,000-30,000 per month just for browser infrastructure. We built a self-hosted alternative using Playwright + LLM for page understanding. It handles 90% of the use cases at a fraction of the cost. This article covers the architecture. For how we build AI workflow systems and agentic AI more broadly, those guides cover the higher-level patterns.…
