Not Just Imagining. Actually Browsing.

LaunchSim agents use real headless Chrome — they see what your users see.

Real Browser Engine

Each agent launches a full Chrome browser instance. No simulated DOM, no mocked responses — real page rendering.

Visual Proof at Every Step

Screenshots captured after each action. See exactly what the agent saw when they got confused or frustrated.

LLM-Driven Decisions

Agents read the actual page content, evaluate interactive elements, and decide actions based on their persona and goals.

Frequently Asked Questions

Traditional QA tests if features work correctly. LaunchSim tests if users can understand and use your product. Our AI agents use real Chrome browsers to interact with your site, producing authentic behavior patterns that reveal UX issues QA can't catch.
Yes. Each agent launches a real headless Chrome instance via Playwright. It navigates to your URL, reads the actual DOM, clicks real elements, types in real input fields, and takes screenshots at every step. This is not simulation — it's actual browser automation driven by AI.
Each agent has a unique persona with specific age, occupation, tech level, patience level, and personality traits. A 65-year-old retired teacher will interact very differently from a 28-year-old frontend developer. The LLM makes decisions based on the real page content the agent sees.
Typically 3-10 minutes depending on agent count. Each agent performs 6-12 real browser actions. You can watch progress in real-time on the dashboard.
Any publicly accessible website. Landing pages, SaaS products, e-commerce stores, blogs, web apps — if Chrome can open it, our agents can test it.
