Choosing well
Check Android access
Start with Android support if you plan to manage filtering from a Xiaomi, Redmi or POCO phone. Confirm whether the service also offers a web dashboard or apps for Windows, macOS, iOS or Linux.
Platform coverage varies, so match the listed systems with the devices you need to manage.
Compare free plans and trials
A free plan can cover basic DNS filtering without a subscription. Pricing notes also identify services with a free trial, while paid options may show a starting monthly price or require a quote.
Check what the free plan includes before relying on it for your setup.
Match the blocking controls
Compare malware blocking, ad blocking and adult content filtering to the rules you want to apply. Custom blocklists let you add domains beyond the service’s built-in categories.
Look for the combination of controls that fits your household or organisation.
Review device policies and records
Per-device policies let filtering rules differ between devices. Activity logs and an analytics dashboard can show DNS activity and help you review how rules are working.
Check the service details to see which of these management features are available.
Consider open-source code
Open-source projects can be inspected and self-hosted when their licence and documentation allow it. Review the project’s code, setup requirements and update activity before choosing this route.
