A high-performance, Cloudflare-like platform with Bot Protection, Rate Limiting, and DDoS Mitigation at both HTTP (Layer 7) and DNS layers.

• 🛡️ Bot Protection: IP and User-Agent based blocking
• ⏱️ Rate Limiting: Redis-based token bucket (HTTP + DNS)
• 🚫 Anti-DDoS: Request throttling and IP blocking
• 📊 Analytics: High-performance ClickHouse storage
• 🌐 DNS Server: Authoritative DNS with A, CNAME, TXT, MX records
• 🔀 Reverse Proxy: Layer 7 HTTP proxy with security filtering

• Language: Go 1.20+
• Router: Chi
• Database: PostgreSQL (configuration), ClickHouse (analytics)
• Cache: Redis (rate limiting)
• DNS: github.com/miekg/dns

1. Start infrastructure:

   docker-compose up -d

2. Apply migrations:

   docker exec -i goflare_postgres psql -U user -d goflare < migrations/001_create_domains_table.sql
   docker exec -i goflare_postgres psql -U user -d goflare < migrations/002_create_bot_rules_table.sql
   docker exec -i goflare_postgres psql -U user -d goflare < migrations/004_create_dns_records_table.sql
   docker exec -i goflare_clickhouse clickhouse-client --password "" --database goflare_analytics < migrations/003_create_requests_table_clickhouse.sql

3. Run server:

   go run cmd/server/main.go

• POST /api/v1/domains - Add a domain
• GET /api/v1/domains - List domains

• POST /api/v1/bot/rules - Add bot rule
• GET /api/v1/bot/rules - List rules
