The problem: Modern web development moves fast. You're vibe-coding, shipping features, and suddenly your AWS keys are sitting in a <script> 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 tokens, and more.
It's not perfect, there are false positives but it's caught real issues in my own projects. Think of it as a quick sanity check before you ship.
Use case: Run it on staging before deploying, or audit your existing sites. Takes ~30 seconds per page.

There is something seriously wrong in your organization when that's a repeating pattern. Secrets don't just accidentally make their way into the frontend unless the way you manage secrets is fatally flawed. Offensive security tools are great for finding issues by playing the role of an adversary, but they are not the solution to such an already known grave, fundamental, organizational problem.

Secrets exposure is just one of your problems if there are not processes in place to catch this upstream.
That being said, this is a show hn and we should be gentler with criticism. The tool is still very useful even for mature organizations to identify blind spots and process failures.

Ideally I would have loved this to be a chrome plugin or part of the CI/CD pipeline or put it out as an adversary agent for all of these new vibe coded apps but don't think I'm that vested into the idea yet. Thanks for being gentle :)

https://news.ycombinator.com/item?id=45741569 - It was also partly inspired by this as I have seen legacy sites making these mistakes quite often.
With all the vibe coded apps that are getting launched or were launched early, there are enough holes to plug. This is just an attempt to help individuals or orgs to ensure they are not exposed. Just pushed it out what I had in mind based on my experience.
And I agree with you that an adversary approach won't work if we can't fix the underlying problem but the world has changed with enough vibe coded apps that are getting shipped everyday and very little of them care or know about security.
