DNS Cloak

A flexible DNS proxy, with support for modern encrypted DNS protocols including DNSCrypt V2, DNS-over-HTTPS and Anonymized DNSCrypt. Also allows for advanced monitoring, filtering, caching and client IP protection through Tor, SOCKS proxies or Anonymized DNS relays.

Non-root, small-sized DNS changer utilizing DNS-over-HTTPS and DNS-over-TLS. (Note, since this uses Android's VPN API, it is not possible to run a VPN while using Nebulo.)

Free and open source DNS changer with support for DNS-over-HTTPS, DNS-over-Tor, and DNSCrypt v3 with Anonymized Relays. (Note, since this uses Android's VPN API, it is not possible to run a VPN while using RethinkDNS + Firewall.)

Acts as a local DNS Privacy stub resolver (using DNS-over-TLS). Stubby encrypts DNS queries sent from a client machine (desktop or laptop) to a DNS Privacy resolver increasing end user privacy. Stubby can be used in combination with Unbound - Unbound provides a local cache and Stubby manages the upstream TLS connections (since Unbound cannot yet re-use TCP/TLS connections), see example configuration.

Validating, recursive, caching DNS resolve with support for DNS-over-TLS. Designed to be fast, lean, and secure Unbound incorporates modern features based on open standards. It's fully open source, and recently audited. (For an in-depth tutorial, see this article by DNSWatch.)
