Checkout stops converting
A payment step returns 500, a cart action hangs, or a third-party script fails. Customers leave without filing bug reports.
Kizaru Monitor
Founder-operated browser QA pilotKizaru catches broken flows first.
Catch broken user flows before your customers do.
A narrow, founder-operated pilot for revenue-critical pages, forms, signup/login, and checkout flows. Kizaru Monitor runs deterministic browser checks and captures the evidence an operator needs when something breaks.

The problem
Critical flows break quietly.
Uptime checks can say the server is alive while the flow that makes money is already dead. Kizaru focuses on what customers actually try to do.
Forms go silent
Demo, lead, contact, and newsletter forms can look normal while submissions stop reaching your team.
JavaScript errors ship
A deploy, tag manager change, or missing asset can break the page after your CI passed and after the team went home.
HTTP and network failures hide
Broken subresources, 404s, 5xx responses, and request failures need evidence, not vague pings.
Evidence package
Screenshots, logs, failures, report, alert.
Every useful signal stays close to the browser run, so a pilot operator can see what happened without guessing.

How it works
Browser check -> evidence -> report -> alert.
The MVP stays deterministic. Playwright performs agreed checks. The output is structured evidence for human review, not unrestricted browser control.
Browser check
Kizaru opens an authorized URL with Chromium and runs the agreed check.
Evidence
It captures screenshot paths, console errors, HTTP failures, and network failures.
Report
A structured run and deterministic Markdown report make the incident reviewable.
Alert
Pilot alerts can point to the evidence when the check finds something wrong.
Pilot cases
One critical flow is enough to start.
Kizaru is built for measurable workflows where a broken page costs money, trust, or pipeline.
Landing integrity
Title, key copy, rendered page text, screenshot evidence, and broken resources.
Forms
Demo request, contact, newsletter, waitlist, or quote forms with clear success states.
Signup / login
Public signup and login checkpoints using safe pilot data and explicit scope.
Checkout
Cart, payment step visibility, broken scripts, server errors, and final confirmation signals.

FAQ
Short answers, tight scope.
Is Kizaru autonomous browser control?
No. The MVP is deterministic browser QA monitoring. Playwright runs agreed checks; evidence and reports come first.
Does this replace CI end-to-end tests?
No. CI catches regressions before deploy. Kizaru watches selected live flows after deploy.
Do I need to install code on my website?
No SDK is required for the pilot concept. Kizaru checks URLs from a real browser.
Can Kizaru monitor any target?
Only authorized targets should be used. Real customer monitoring waits for written permission, scope, retention, deletion, and operating rules.
What is the temporary logo?
The public site now uses the local PNG set under site/assets/brand/: the hero uses kizaru-lockup-amber.png and the header/favicon use kizaru-mark-amber.png without an extra framed tile. The older SVG placeholder remains only as a local fallback. It is not final brand artwork.
