Reflex CLI by Lucid Layer

Simulate real users. Catch broken UX before launch.

What is Reflex?

Reflex is a CLI tool that spins up a headless browser, simulates real user flows, and uses AI to instantly find UX issues before you ship.

• Goal-driven: Simulate specific user goals.
• Persona-aware: Emulate different user types.
• Instant feedback: Get actionable reports in seconds.
• CLI-first: Fits right into your dev workflow.
• No more guesswork: Ship with confidence.

Installation

Global:

npm install -g @lucidlayer/reflex

Or with npx (zero install):

npx @lucidlayer/reflex http://localhost:3000

IMPORTANT: Set your OpenRouter API key

Reflex CLI requires an OpenRouter API key to generate UX feedback.

1. Get your API key:
   Sign up at https://openrouter.ai and copy your API key.

2. Create a .env file (or .env.local, .env.development, .env.production) in your project or home directory with:

REFLEX_OPENROUTER_API_KEY=sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

3. Or pass it as a CLI flag:

uxcheck http://localhost:3000 --apiKey sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

If you don’t set your key, you will get a 401 Unauthorized error.

Usage

Basic scan:

uxcheck http://localhost:3000

With custom goal and persona:

uxcheck http://localhost:3000 --goal "Try to sign up" --persona "new user"

Save JSON report:

uxcheck http://localhost:3000 --json
