Show HN: Build Web Automations via Demonstration

https://www.notte.cc/launch-week-i/demonstrate-mode
19•ogandreakiro•1d ago
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 infrastructure

Closest 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 fallback

Agents 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.

Congrats on the launch and nice identity. You might want to check Selenium as a source of inspiration

Interesting but are there any open source products which can do the same too? This does feel something that I can trust more if it was open source personally but good luck with the product!

Playwright codegen.

Browser use has a project "Workflow Use" that has similar aims: https://github.com/browser-use/workflow-use

Using this, if a first time user logs in, could we share automated scripts, that they can execute to create sample workflows?

Why is this not a Launch YC (or at least mention it?) since you seem to be part of the current batch?

The record/replay is definitely and interesting direction. The browser automation space is getting super crowded though (even within YC), so curious to hear how you differentiate from:

- BrowserUse

- Browserbase

- BrowserBook

- Skyvern

pardon me but arent there like 5000 startups that do this exact same thing

I do this with Chrome recording and Playwright. What I need is an AI agent to meander through my product as if it were the target user and test/break things so I can pass that to my LLM to fix. Does anyone have that?

We're full circle to "Programming by Demonstration" (1993) https://acypher.com/wwid/ or Pygmalion (1975), though this iteration probably works better :)
