Notte, the startup behind browser agents, unveiled Demonstrate Mode, a tool that records a user’s workflow in a cloud browser and turns it into deterministic automation code. The process captures clicks, inputs, and navigation, then compiles the data into scripts that run without an LLM at runtime for production use.

Unlike traditional codegen tools like Playwright codegen, Demonstrate Mode hands off infrastructure: remote browsers, proxies, and authentication states are managed automatically. The generated scripts execute on a deployable runtime that logs activity, retries failures, and can fall back to an agent for edge cases in production environments to ensure reliability.

Founders Andrea and Lucas emphasize that deterministic scripts offer versioned, predictable cost and behavior, while agents remain useful for prototyping. By eliminating runtime LLMs, teams can deploy automation with tighter control over execution time and resource usage, a key advantage for scaling web workflows across diverse applications and teams worldwide.

Notte invites developers to test the demo via a Loom video and promises deeper implementation details in comments. As web automation matures, tools that combine recording, deterministic code, and managed infrastructure will likely become standard, reducing reliance on ad‑hoc scripting and improving reliability for production workloads in the future of automation.
