Hey Product Hunt I'm Todd. I build apps live on Twitch, and for two years I've had the same low-grade fear running in the background: one careless cat .env, one wrong window shared, and an API key is on the internet forever.
Every tool I found to "blur my screen" was a browser extension which is useless, because you don't leak secrets in a Chrome tab. You leak them in your terminal, your editor, a .env file, a database GUI. So I built Censr: a Mac app that watches whatever you're sharing and blacks out API keys, passwords, and PII before they reach your stream or screen-share. It shows up as a virtual camera in OBS, Zoom, Meet & Discord, runs 100% on-device, and has a panic hotkey ( B) for the "oh no" moments.
The one thing I won't claim: that it's perfect. No detector is. It's defense in depth a safety net for the slip-ups you can't catch yourself not a "100% safe" promise. I'd rather be honest about that than oversell it.
We launch July 1. Two questions for this crowd while I've still got time to act on the answers:
Censr is a Mac app that automatically blacks out API keys, passwords, and personal data on your screen — before they ever hit your livestream or screen-share. System-wide (terminal, editor, browser, native apps — not just a browser tab), 100% on-device (nothing uploaded), and it shows up as a virtual camera in OBS, Zoom, Meet & Discord. Follow to get notified at launch — the first 100 founding members get it for $19.
