From Grok:
Google Chrome + Google Family Link (Best overall for most families)
Use Chrome on a child Google account managed by Family Link (free from Google).
Parents can block inappropriate sites, enable SafeSearch, set screen time limits, approve apps/downloads, and monitor activity.
Safari + Apple Screen Time (Best if you have Apple devices — iPad/iPhone/Mac)
Built-in parental controls let you restrict adult websites, set time limits, and approve downloads.
Microsoft Edge with Family Safety (Good Windows option)
Integrates with Microsoft Family Safety for content filtering, screen time, and activity reports.
Dedicated Kid-Safe Browsers
For stronger built-in filtering (especially if you want something harder to bypass):
SPIN Safe Browser (often paired with parental control apps like Boomerang) — Aggressive blocking of inappropriate content.
Kiddle or KidzSearch — Kid-focused search with filtered results.
Key Tips for Maximum Safety
Combine with parental controls — A browser alone isn't enough. Use device-level tools (Family Link, Screen Time, or a third-party app like Qustodio/Bark if needed).
Supervise initially — Teach your child basic online safety rules.
Avoid plain incognito mode or unmonitored browsers — kids can sometimes find workarounds.
Enable SafeSearch on Google/Bing and block YouTube in the browser if needed (or use YouTube Kids separately).
