Building a Serverless Autonomous Web Agent: Lessons Learned from Deploying Otobot

Deploying autonomous AI agents into production introduces unique challenges—especially when executing real-time browser actions inside cloud-hosted, serverless environments.
Rather than relying on static local instances, I built Otobot to operate completely in the cloud using Node.js, Playwright, and dynamic LLM task-planning loops.
What Makes This Architecture Different?
Adaptive Action Planning: Instead of running sequential pre-defined scripts, the agent interprets raw DOM structures and plans its next action autonomously.
Serverless Scalability: Optimized backend pipeline running on Render to spin up headless browser contexts on demand without heavy memory overhead.
Self-Healing Execution: Handles unpredictable popups, dynamic layout shifts, and modern UI frameworks without script failures.
