Why

Data-driven product decisions through event tracking, funnels, and dashboards. PostHog and Plausible offer privacy-first analytics without GDPR consent banners, growing 200% in 2024.

BigQuery and ClickHouse process petabyte-scale data at $5/TB scanned.

When

Use for product analytics, user behavior, and BI reporting. Avoid for simple page-view counting (use Plausible).

How

1. Create Crazy Egg account/project 2. Add tracking SDK 3. Define events/metrics 4. Build dashboards

Example

// Crazy Egg tracking analytics.track('button_clicked', { id: 'signup' }); // Crazy Egg — usage example import { CrazyEgg } from "analytics-crazyegg"; const result = await crazyegg({ input: "data" }); console.log(result);

Common Problems

  • ⚠Crazy Egg event volume explosion — sample high-cardinality events
  • ⚠GDPR consent not enforced — gate tracking behind consent banner
  • ⚠Configuration drift between environments — use infrastructure-as-code (Terraform/Pulumi) to keep dev/staging/prod identical

Best Practices

  • ✓Define a consistent event taxonomy before implementing Crazy Egg
  • ✓Use server-side tracking for accuracy and ad-blocking resilience
  • ✓Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit

What are the best practices for Crazy Egg?

Best practices for Crazy Egg include: Define a consistent event taxonomy before implementing Crazy Egg; Use server-side tracking for accuracy and ad-blocking resilience; Set up health checks and graceful shutdown — handle SIGTERM to drain in-flight requests before exit. The first one — "Define a consistent event taxonomy before implementing Crazy Egg" — should be set up at project init to avoid costly rework later.

When should I NOT choose Crazy Egg?

Pick something else in three cases: (1) the team has zero experience with the core framework and the deadline is tight (learning-curve risk); (2) it's a pure content/marketing site (Astro is lighter); (3) you need very high throughput (>10k RPS) or strict-consistency microservices (Go/Rust). Crazy Egg shines for mid-to-high complexity full-stack and API work — don't over-engineer simple static pages with it.
