ReplacesGoogle Analytics, Plausible

Core Analytics

Pageviews, Sources, and Visitors

  • Lightweight Tracking Script

    Under 2 KB of JavaScript. No external dependencies, no cookies, no localStorage. Served from your own domain via t.renkara.com.

  • Real-Time Dashboard

    Live visitor count, active pages, and incoming traffic sources. No sampling, no delays. See what's happening right now.

  • Traffic Source Breakdown

    Referrers, UTM campaigns, search engines, social platforms, and direct traffic. Automatic source categorization with campaign parameter parsing.

  • Geographic and Device Analytics

    Country, browser, OS, and device type breakdowns. No IP storage — geography derived from request headers and immediately discarded.

Conversion Tracking

Goals, Funnels, and A/B Tests

  • Goal Tracking

    Define goals by URL pattern or custom event name. Track conversion rates over time with automatic visitor attribution.

  • Funnel Analysis

    Multi-step conversion funnels showing drop-off at each stage. Identify where visitors abandon the path from landing to conversion.

  • A/B Testing

    Built-in experiment framework for comparing page variants. Statistical significance calculation without external tools.

  • Custom Events

    Track any user action with pulse.track('event_name', {props}). JSONB property storage for flexible event metadata.

Privacy & Infrastructure

Compliant by Design

  • Zero Cookies

    No cookies, no localStorage, no fingerprinting. Visitor identification uses a daily-rotating hash that cannot be reversed to identify individuals.

  • Public Dashboards

    Share read-only analytics dashboards via unique URLs. No authentication required for viewers. Full transparency with your audience.

  • Multi-Site Management

    Monitor multiple domains from a single account. Per-site configuration, allowed domain lists, and independent tracking snippets.

  • Webhook Integrations

    Push analytics events to external systems via webhooks. Milestone notifications when traffic goals are reached.

Accessibility

Built for Everyone

  • WCAG 2.1 AA Compliance

    4.5:1 contrast for body text, 3:1 for large text and UI components, in both light and dark themes.

  • Keyboard Navigation

    Every interaction reachable via keyboard. Logical tab order, visible focus indicators, Escape-to-dismiss for modals.

  • Screen Reader Support

    VoiceOver, NVDA, and JAWS tested. Semantic HTML, ARIA labels, live regions for dynamic updates.

  • Reduced Motion

    Respects prefers-reduced-motion. Usable at 200% zoom. Touch targets meet 44x44 minimum.

How It Works

From Script to Insight

  1. Step 1: Install

    Add a single <script> tag. Under 2 KB, no dependencies, loads asynchronously.

  2. Step 2: Collect

    Pageviews and events stream to the collection endpoint. No cookies set, no personal data stored.

  3. Step 3: Analyze

    Real-time dashboards, traffic breakdowns, conversion funnels, and A/B test results. All in one place.

  4. Step 4: Act

    Set goals, track conversions, run experiments. Make decisions based on data you actually own.

Development

100% Built by Claude

Every tool in the Renkara fleet was built by Claude (Anthropic) working alongside a single human supervisor. Every line of code, every test, every deployment: AI-authored with human direction. The leverage factor across the fleet runs in the 20x–50x range, with individual sessions regularly exceeding 100x.
