Stop silent failures in your AI-built apps

Vibe-coding is fast, but it's risky. We automatically monitor your complex flows so you can build at AI-speed without breaking the user experience.

🔥 Join 200+ founders ship-readying their AI-built apps.

The AI-Build Tax is Real

Ship 10x faster, but spend 100x longer manually checking if "Sign up" still works after every vibe-change.

Broken Logic

AI sometimes breaks existing features while adding new ones. You only find out when users complain.

Silent Failures

API responses change, but the UI keeps spinning. Your dashboard looks fine, but it's empty.

Zero Monitoring

Writing Playwright scripts takes too long. Most AI-built apps have zero automated coverage.

Zero Test Code.
Just Vibe-Proofing.

We use your app like a real human would. No brittle selectors or messy code.

Step 1

Auto-Discovery

Our engine explores your URL and uses AI to understand your app's purpose. It finds the "Add to Cart", "Sign Up", and "Dynamic Charts" flows automatically.

Step 2

Shadow Monitoring

We run invisible browsers every 15 minutes. If a button moves or an API fails, we catch it before your customers do.

Step 3

Visual Proof

Get a notification with a video and a full trace when things break. No more "I can't reproduce it" Slack messages.

Trace log: flow_sign_up_042
ERROR: Timeout
Failed: Submit
Enter Email

Monitor everything,
worry about nothing.

Zero-Config

No JSON configs. No YAML. Just a URL and your app's vibe.

Smart Auth

Logs into your app using credentials or magic links automatically.

Scheduled Runs

Monitor every 15 minutes, hourly, or daily based on your needs.

Visual Traces

See exactly what the browser saw with full DOM snapshots and videos.

Slack Alerts

Ping your team immediately when a critical flow starts failing.

AI Explainer

AI summarizes the failure so you know exactly what broke in plain English.
