LogForge by David Vilaverde

LogForge transforms your browser into a realistic access log generator. As you browse, it captures HTTP requests and formats them exactly like production web server logs—perfect for testing log parsing pipelines, monitoring systems, and analytics tools.

Key Features:
• Multiple log formats: Apache, Nginx, Envoy, HAProxy, IIS, and CDN formats (Cloudflare, Fastly, Akamai, CloudFront)
• Custom format editor with Apache-style variables (%h, %t, %r, %s, etc.)
• Domain filtering to capture specific sites only
• Public IP lookup for realistic log entries
• Persistent storage—logs survive browser restarts

Use Cases:
• Testing custom log processors or log ingestion pipelines
• Validate log format configurations before production deployment
• Generate sample data for QA testing and demos
• Debug log ingestion pipelines with real traffic patterns

Privacy-focused: Captures only server-visible metadata (URLs, headers, status codes, timing)—no request/response bodies, localStorage, or JavaScript data.
