Build CloudWatch JSON and space-delimited metric filter syntax patterns.
Execution runs 100% locally inside the browser sandbox using HTML5 Canvas, Web Cryptography Subtle API, and Web Workers. Zero egress.
Zero network latency. Operates completely offline with zero dependencies on third-party backend servers or cloud services.
Built according to official RFC specifications, cryptographic test vectors, and enterprise-grade data transformation standards.
Choose JSON Logs or Space-Delimited Access Logs.
Configure property paths ($.status_code) and operators.
Paste into CloudWatch Metric Filter or Subscription Filter.
{ $.status_code >= 500 } matches all 500-level HTTP error responses.
Yes, syntax like { $.level = 'ERROR' } filters by exact string matches.
Zero-egress companion tools in the Security & Network suite
Measure cryptographic randomness, Shannon entropy (0-8 bits/byte), Chi-square test, and byte distributions.
Brute-force all 256 single-byte XOR keys with automated English frequency & chi-squared scoring.
Audit CSP, HSTS, X-Frame-Options, and security headers with OWASP grading (A+ to F).
Compare memory hardness, GPU ASIC resistance, and security parameters across KDF standards.
