Browser evidence for AI-built apps
Your app didn't behave as expected.See What Happened, Step by Step
NodeLume correlates clicks, page changes, browser events, and network requests in one local visual timeline, giving you and an AI coding assistant concrete evidence to diagnose the issue.
No debugging experience required. No raw logs or complex developer tools. Capture data stays in your browser.
NodeLume — Debug what AI built.
Use NodeLume free without an account, login, or subscription: unlimited site analyses, 3 recordings, and 3 problem analyses. Sign in only to subscribe to Core or manage a paid plan.
HOW IT WORKS
Connect the visible symptom to the browser activity behind it.
Instead of comparing a screen recording with a separate Network panel, NodeLume keeps the user journey and technical signals on the same timeline.
Record the real path
Reproduce the issue normally while NodeLume aligns UI actions, page changes, events, and requests.
Inspect the turning point
See the exact action, request, or event immediately before the flow changed, stopped, or returned an unexpected result.
GET STARTED
From Chrome installation to your first capture.
Install NodeLume and start with the free usage included in the extension. There is no desktop app, server setup, account, or subscription required.
Install in Chrome
Add the NodeLume extension to Chrome and pin it for quick access while you work in a web app.
Use it without an account
Open the extension and use the included free analyses. No login or subscription is required.
Subscribe to Core when you want
Keep using NodeLume free without an account, login, or subscription, or subscribe to Core for higher limits. Paid subscriptions are charged immediately.
Record and inspect
Open your app, start recording, reproduce the real journey, and inspect the result directly in Chrome.
WHAT YOU CAN INSPECT
The context a screenshot or error message leaves out.
Each capture keeps the useful layers connected so you can move from the visible symptom to a likely cause.
Instant app map
See pages, buttons, menus, forms, and paths as a simple visual map.
Synchronized recording
Keep UI actions, page changes, browser events, and requests in the sequence they occurred.
Request details
Identify successful, failed, repeated, or slow requests without reading raw browser logs.
Useful signals
Surface slow steps, hidden failures, and third-party services that may explain the result.
Local history
Reopen earlier maps and recordings, keep useful captures, and delete the rest.
AI-ready handoff
Share a structured visual record with an AI coding assistant instead of retelling the issue from memory.
WHAT MAKES NODELUME DIFFERENT
One sequence, from human action to network response.
PRIVACY ARCHITECTURE
Capture data stays in the browser.
NodeLume has no analysis backend, telemetry pipeline, or cloud sync. Captures are processed and stored in the Chrome extension. Full network recording is opt-in, limited to the recorded tab, and protected by explicit permissions.
Read the privacy details →No analysis serverMaps and recordings are not uploaded to NodeLume.
Explicit recording consentBroader host permission is requested only when a complete recording starts.
Permission is removedOptional host access is revoked automatically when recording finishes.
Manual data controlYou choose which local captures to keep, open, or delete.

Clear boundaries. Practical answers.
Do I need to understand code or browser logs?
No. NodeLume presents the browser journey as a visual sequence that is easier to inspect and explain.
Does NodeLume send captures to a server?
No. App analysis stays in local Chrome extension storage and is not uploaded to NodeLume.
What is the difference between an instant map and a recording?
The instant map inventories the visible pages and controls. A recording follows the path you take and aligns each action with the resulting page change, event, and request.
How does NodeLume work with an AI coding assistant?
The capture provides concrete, ordered evidence about the user flow and browser activity, so the assistant can reason from more than a screenshot or error message.
