AI-native CRM that builds itself and does work for you

Hey Product Hunt! 👋

I built KidGuard because I couldn't find a simple, free parental control tool that actually worked reliably on YouTube.

Most tools either cost money, require an account, or fail to catch content because YouTube is a single-page app that doesn't reload between videos.

KidGuard solves that by intercepting navigation BEFORE pages load, watching for DOM changes with MutationObserver, and checking video titles via YouTube's oEmbed API — all before your child sees anything.

It's completely free and open source.

Happy to answer any questions — would love your feedback! 🙏

🆕 KidGuard just got a major upgrade — ⏰ Screen Time Limits are here!

I just shipped one of the most requested features: daily time limits for any website.

Here's how it works:

⏱ Set a daily time limit for any site

Add youtube.com, tiktok.com, roblox.com — or any domain you want — and set how many hours and minutes per day your child is allowed. Default is 1 hour.

📊 Live progress bar

Every site shows a real-time progress bar so you can see exactly how much time has been used today:

🟢 Green — under 80% used

🟡 Amber — almost up

🔴 Red — limit reached and blocked

🔒 Automatic blocking

When the daily limit is reached, the site is redirected to a block page — automatically, with no manual intervention needed. The block page shows exactly how much time was used and when the limit resets.
