Pros of AdGuardHome

• More comprehensive DNS filtering and ad-blocking solution
• User-friendly web interface for easy configuration
• Supports multiple upstream DNS providers

Cons of AdGuardHome

• Higher resource usage due to additional features
• More complex setup process
• Larger codebase, potentially harder to maintain

Code Comparison

AdGuardHome (Go):

func (d *DNSFilter) CheckHost(host string, qtype uint16, setts *FilteringSettings) (Result, error) {
    // Complex filtering logic
}

mosdns (Go):

func (h *Handler) Match(ctx context.Context, qCtx *query_context.Context) (bool, error) {
    // Simpler matching logic
}

Summary

AdGuardHome offers a more feature-rich DNS filtering solution with a user-friendly interface, while mosdns provides a lightweight and flexible DNS forwarding tool. AdGuardHome is better suited for users seeking a comprehensive ad-blocking and DNS management system, whereas mosdns is ideal for those who need a simple, customizable DNS forwarder with basic filtering capabilities.

Pros of dnscrypt-proxy

• Supports a wide range of DNS protocols, including DNSCrypt, DNS-over-HTTPS, and DNS-over-TLS
• Offers advanced features like DNS caching, load balancing, and anonymized DNS
• Has a large user base and active community support

Cons of dnscrypt-proxy

• Configuration can be complex for beginners
• Limited built-in DNS filtering capabilities
• May have higher resource usage compared to simpler DNS proxies

Code Comparison

dnscrypt-proxy (Go):

func (proxy *Proxy) exchangeWithCache(serverInfo *ServerInfo, encryptedQuery []byte, clientNonce []byte) ([]byte, error) {
    cachedResponse, err := proxy.localCache.Get(encryptedQuery)
    if err == nil {
        return cachedResponse, nil
    }
    // ... (additional code for DNS exchange)
}

mosdns (Go):

func (h *Handler) Lookup(ctx context.Context, q *dns.Msg) (*dns.Msg, error) {
    if r := h.cache.Get(q); r != nil {
        return r, nil
    }
    // ... (additional code for DNS lookup)
}

Both projects use Go and implement DNS caching, but dnscrypt-proxy focuses on encrypted DNS protocols, while mosdns provides more flexibility in DNS query handling and plugin-based architecture.

Pros of dns

• More mature and widely adopted project with a larger community
• Comprehensive DNS library with support for various DNS-related operations
• Extensive documentation and examples available

Cons of dns

• Focused solely on DNS functionality, lacking built-in DNS server features
• Requires more setup and configuration for advanced use cases
• May have a steeper learning curve for beginners

Code Comparison

mosdns:

package main

import "github.com/IrineSistiana/mosdns/v5/coremain"

func main() {
    coremain.Main()
}

dns:

package main

import (
    "github.com/miekg/dns"
    "net"
)

func main() {
    dns.HandleFunc(".", handleDNSRequest)
    server := &dns.Server{Addr: ":53", Net: "udp"}
    server.ListenAndServe()
}

mosdns provides a more streamlined approach for setting up a DNS server with built-in functionality, while dns offers greater flexibility but requires more manual configuration.

Pros of CoreDNS

• More mature and widely adopted project with extensive documentation
• Highly extensible plugin architecture
• Supports multiple DNS protocols (DNS, DoH, DoT)

Cons of CoreDNS

• Larger codebase and potentially higher resource usage
• Steeper learning curve for configuration and customization
• May be overkill for simpler DNS requirements

Code Comparison

mosdns configuration example:

log:
  level: info
plugins:
  - tag: forward
    type: forward
    args:
      upstream:
        - addr: 8.8.8.8

CoreDNS configuration example:

.:53 {
    forward . 8.8.8.8
    log
    errors
}

Key Differences

• mosdns is designed specifically for DNS manipulation and filtering
• CoreDNS offers a more comprehensive DNS server solution
• mosdns configuration uses YAML, while CoreDNS uses its own Corefile format
• mosdns focuses on performance and flexibility for DNS operations
• CoreDNS provides broader functionality beyond basic DNS serving

Both projects serve DNS-related purposes, but mosdns is more specialized for DNS manipulation, while CoreDNS offers a full-featured DNS server with extensive plugin support.
