Best Internet Filtering Tools | Safe Browsing

Tech Lockdown

Multi-layered DNS content filtering platform with bypass prevention tools and an Apple Device Config Generator, now adding opt-in Mobile Device Management (Remote Supervision, early access) for real-time, remotely-enforced restrictions on Apple devices; paired with the sibling iOS app LivingRoom for Families — screenshot-based monitoring with automatic nudity detection — operated separately under LivingRoom App LLC. Founded by Ben Bozzay, a Christian developer who built it as a practical tool for freedom from pornography and digital addiction.

Clearplay

Clearplay is a Chrome extension for Windows and Mac computers that skips or mutes violence, language, and sexual content in real time on Amazon, Apple TV, Disney+, HBO Max, and Netflix. Filtering requires ad-free subscription tiers — including a paid ad-free add-on for Amazon Prime — and is designed and supported for use in the United States only. Founded in 1998 by brothers Matt and Lee Jarman, Clearplay helped pass the Family Movie Act of 2005 and states it will not build phone, smart-TV, or streaming-box apps because those environments would require an unauthorized copy of the stream.

Glorifind Search Engine

Glorifind is a free, ad-supported whole-web search engine for Christians, with always-on safe search, ranking that prefers quality Christian sources when they are relevant, and a gold border for known Christian-owned sites. It is available as a website and as Chrome, Edge, Firefox, and Safari options, and the same creator also built ABCSearch.org for kids and schools.

Now part of Aura (ASX: AXQ) following the July 17, 2026 completion of Aura's acquisition of Qoria; Aura's first post-close earnings (Aug 5, 2026) reported pro forma ARR of $339.7M (+27% YoY) and reaffirmed 2026 growth targets.
