Introduction

Learn what Apperio is and how it helps you monitor your applications in real-time.

What is Apperio?

Apperio is a comprehensive observability and logging platform that helps developers monitor, debug, and optimize their applications in real-time. Stop guessing what is breaking in production -- Apperio gives you full visibility into your application's behavior with minimal setup.

With a lightweight JavaScript SDK, a powerful REST API, and an intuitive dashboard, Apperio captures errors, tracks performance, monitors network requests, and provides actionable insights across your entire stack.

Key Features

  • Auto-Instrumentation -- Automatically capture errors, performance metrics, network requests, console output, page views, and user interactions with zero manual code.
  • 6-Level Logging -- Full logging hierarchy from trace to fatal, with smart level assignment based on event context.
  • Real-Time Monitoring -- WebSocket-powered live log streaming and dashboard updates as events happen.
  • PII Sanitization -- Built-in detection and redaction of 10+ PII patterns including emails, SSNs, credit cards, API keys, and JWTs.
  • Performance Tracking -- Core Web Vitals (LCP, FID, CLS, TTFB, INP), page load times, and endpoint response analysis.
  • Alerting System -- Configurable alert rules with email, Slack, and webhook notification channels.
  • Team Collaboration -- Multi-project management with team members, roles, and shared dashboards.

How It Works

Apperio follows a simple three-step flow to collect, process, and visualize your application data:

Bash
# 1. Your App(SDK)
#    Captures events automatically or via manual API calls
#    Batches logs(default: 10 per batch, every 5 seconds)
#    Sanitizes PII data before transmission
#           |
#           v
# 2. Apperio API(Backend)
#    Receives log batches via POST /:projectId/logs
#    Validates and stores in MongoDB
#    Broadcasts to WebSocket subscribers
#    Evaluates alert rules
#           |
#           v
# 3. Dashboard(Frontend)
#    Real-time log stream viewer
#    Analytics and charting
#    Error grouping and analysis
#    Performance monitoring

Minimal Performance Impact

The SDK batches logs and uses exponential backoff retry logic to minimize network overhead. Default configuration sends at most 2 requests per 10 seconds.
