Coding tutorials. Live streams. Course recordings. Every video you make puts your secrets at risk. StreamBlur automatically blurs API keys, tokens, and passwords - so you can focus on teaching.
No more re-recording videos. No more post-production blur edits.
From 5-minute tutorials to full course recordings, StreamBlur has you covered.
Recording a step-by-step tutorial? StreamBlur ensures your real API keys don't end up in your footage - even if you forget to swap them out.
Live coding on YouTube? There's no post-production safety net. StreamBlur's Stream Mode gives you real-time protection so your audience never sees your secrets.
Building a Udemy or YouTube course? Hours of screen recording means more chances to accidentally show credentials. StreamBlur protects every frame.
Showing how to deploy to AWS, Vercel, or Railway? Cloud dashboards are full of secrets. StreamBlur blurs them across every cloud console.
Teaching your audience how to integrate Stripe, Twilio, or OpenAI? Show the real workflow without exposing your actual API keys.
Walking through a full-stack project? Config files, environment variables, and cloud dashboards are all protected automatically.

Leave a Review on Chrome Web StoreYes! StreamBlur blurs content at the browser level, so any screen recorder (OBS, ScreenFlow, Loom, Camtasia) captures the already-blurred version. Your viewers see the blur, not your secrets.
Absolutely. Since StreamBlur works in real-time, your live stream audience sees blurred secrets. No delay, no additional setup - just go live with confidence.
Yes. StreamBlur's blur is clean and consistent - it looks intentional, like a deliberate privacy measure, not like a mistake you had to patch in post.
Of course. Toggle Stream Mode off with Alt+Shift+S, show your test/demo key, then toggle it back on. You're in full control.
Immediately revoke and rotate the compromised key. Then install StreamBlur so it never happens again. See our security blog for a step-by-step incident response guide.
