Hey HN,We’ve been building browser agents for a while. In production, we kept converging on the same pattern: deterministic scripts for the happy path, agents only for edge cases. So we built Demonstrate Mode.The idea is simple: You perform your workflow once in a remote browser. Notte records the interactions and generates deterministic automation code.How it works: - Record clicks, inputs, navigations in a cloud browser - Compile them into deterministic code (no LLM at runtime) - Run and deploy on managed browser infrastructureClosest analog is Playwright codegen but: - Infrastructure is handled (remote browsers, proxies, auth state) - Code runs in a deployable runtime with logs, retries, and optional agent fallbackAgents are great for prototyping and dynamic steps, but for production we usually want versioned code and predictable cost/behavior. Happy to dive into implementation details in the comments.Demo: https://www.loom.com/share/f83cb83ecd5e48188dd9741724cde49a-- Andrea & Lucas, Notte Founders

Could you build this?
Partial Capturing browser DOM events and translating them to Playwright/Puppeteer scripts is achievable, but cloud sandboxing and resilient locator synthesis require dedicated browser infrastructure engineering.
What it would actually take: The architecture combines a headless remote browser stream (WebRTC/CDP) with a client-side recorder that hooks into input and DOM mutation events. The challenging piece is synthesizing resilient element selectors and self-healing automation logic that doesn't break when DOM trees mutate, requiring strong browser automation and distributed remote container infrastructure.
