Show HN: Kasbah Guard – Free browser extension that catches API keys before you leak themWe just launched Kasbah Guard, a free browser extension that detects and blocks 50+ secret formats (API keys, tokens, credentials, AWS keys, GitHub PATs, etc.) using ML entropy scoring + context filtering.It runs 100% locally in your browser (no server calls, no data collection). We built this because existing tools (like Snyk) only catch ~30 secret types, and regex-based detection has too many false positives.Key innovation: Naive Bayes multi-feature classifier that analyzes Shannon entropy, character transitions, bigram frequency, and context to distinguish real secrets from test fixtures and docstring

Its activity falls under show hn launch; the profile below is assembled from public directory data.
