What it does
Supaleak scans live websites for exposed API keys, tokens, JWTs, Supabase keys, and other sensitive data before attackers do. For teams shipping fast with vibe coding, it checks real JavaScript files, validates leaks, and sends alerts so you can fix issues before they reach production. Features - Detect API keys, tokens, JWTs, Supabase keys, and more - Validates if leaked secrets are usable - Scheduled scans (daily, weekly, custom) - Email alerts on new leaks - CSV export for audits
Automatically scan websites to detect exposed API keys, tokens, and sensitive data before attackers do.
development teams are shipping faster than ever. , visual coders, low-code tools, and rapid prototyping mean code is deployed in hours, not weeks. while this speed enables innovation, it also increases the risk of exposing sensitive credentials—api keys, tokens, and secrets—in javascript files. supaleak provides continuous monitoring of your production websites, automatically scanning javascript files for exposed secrets after launch . catch leaks before attackers do, minimize security risks, and protect your infrastructure—all while maintaining your development velocity. Add single URL or bulk import multiple websites from file (.txt or .csv) Scans detect potential secrets, but many are…from supaleak.com

KeyLeak Detector – Scan websites for exposed API keys and secretsNov 2025 · github.com · ▲30I built this after seeing multiple teams accidentally ship API keys in their frontend code. The problem: Modern web development moves fast. You're vibe-coding, shipping features, and suddenly your AWS keys are sitting in a tag visible to anyone who opens DevTools. I've personally witnessed this happen to at least 3-4 production apps in the past year alone. KeyLeak Detector runs through your site (headless browser + network interception) and checks for 50+ types of leaked secrets: AWS/Google keys, Stripe tokens, database connection strings, LLM API keys (OpenAI, Claude, etc.), JWT…

Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
