Live Checkout Friction Monitor
Privacy-first telemetry for OpenCart checkout operations.
A lightweight OpenCart extension that captures anonymous checkout friction signals, stores them only in short-lived local files, and renders a live owner dashboard without Redis, Node.js, or custom extension tables.
Features
Operational telemetry without adding infrastructure sprawl.
Live Checkout Metrics
Track active friction signals, recent events, and checkout patterns in real time from the module dashboard.
Sanitized Event Intake
Incoming frontend events are allow-listed, normalized, and stripped of sensitive customer input before they ever touch disk.
Short-Lived Local Storage
Events expire automatically based on the configured retention window, keeping the dataset small and operationally cheap.
Filesystem Rate Limiting
Per-session request limiting blocks burst abuse without requiring Redis or another external rate-limiting service.
Preview Mode
Simulate realistic checkout activity directly in the owner dashboard without writing synthetic events into live storage.
OpenCart Native UI
Built into the module settings experience and styled to fit the Bootstrap-based OpenCart admin rather than introducing a foreign app shell.
How it works
From checkout interaction to live dashboard signal in five steps.
- 01
Checkout route is detected
An OpenCart footer event checks whether the current storefront request looks like a checkout route before any tracking script is injected.
- 02
Frontend tracker sends an event
The checkout script posts a short anonymous JSON payload to the tracking endpoint with a session-scoped token and a signal type.
- 03
Request is validated and sanitized
The catalog controller verifies method and token while the sanitizer removes anything outside the safe payload schema.
- 04
Event is stored locally
Valid events are written to JSON files under OpenCart storage and rate-limit state is kept alongside them in the same local runtime area.
- 05
Dashboard feed refreshes
The admin module page polls the feed endpoint and updates metrics, recent events, and preview scenarios without a page reload.
Privacy by design
Designed for store owners who need actionable checkout visibility without collecting customer-sensitive data.
- No customer form values are stored.
- No payment data is stored.
- No Redis, Node.js backend, or external queue is required.
- No custom monitoring database tables are created.
- Event payloads are anonymous, short-lived, and allow-listed.
- Synthetic preview events never contaminate live monitoring storage.

Frequently asked questions
Does this add a shopper-facing widget to checkout?
No. The extension is owner-facing only. It injects the tracker in the background and keeps the customer-facing checkout visually untouched.
Does it require Redis or a separate real-time backend?
No. Storage, rate limiting, and feed generation are all handled locally using OpenCart storage paths and standard PHP runtime behavior.
What data is actually stored?
Only short anonymous friction events that survive the sanitizer. No payment data, no customer form values, and no custom monitoring tables are created.
Can I preview the dashboard before real traffic arrives?
Yes. Preview mode simulates realistic checkout activity in the owner dashboard without writing fake events into the live storage area.
Will this fit the existing OpenCart admin interface?
Yes. The module is intentionally styled to align with the native OpenCart admin experience and Bootstrap-based component language instead of looking like an external SaaS embed.
Need cleaner checkout visibility?
This extension gives operators a live view of friction without adding infrastructure or bloating the storefront.
