SecretSentinel
Detect hardcoded secrets in VS Code before you commit them
SecretSentinel launched on March 19, 2026.
What it does
SecretSentinel scans your code in real-time and flags hardcoded API keys, passwords and credentials before you commit them. Unlike GitHub's secret scanning which catches leaks after you push, this stops them at the source — your editor. Uses Shannon entropy scoring to catch secrets that don't match any known pattern. Also scans git history, comparesenv files, and generates security reports. Free. Works offline. Your code never leaves your machine.
Extension for Visual Studio Code - Real-time secret & credential leak detector for VS Code. Detects API keys, passwords, tokens and private keys before you commit.
Real-time secret and credential leak detector for VS Code. Detects API keys, passwords, tokens and private keys before you commit. Every week, developers accidentally push API keys, database passwords, and private keys to GitHub. By the time you notice, bots have already scraped your credentials. SecretSentinel stops leaks at the source — your editor, before you ever commit. Scans your code as you type and highlights secrets instantly with color-coded severity underlines. Detects secrets from 60+ providers including AWS, Google, Azure, OpenAI, GitHub, Stripe, Slack, Twilio, SendGrid, MongoDB, PostgreSQL and many more. Uses Shannon entropy scoring to flag high-randomness strings that look…from marketplace.visualstudio.com

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
