## 📖 What is OpenFlare?
**OpenFlare** is a modern, open-source **distributed reverse proxy and edge security gateway platform** designed for multi-server infrastructures and edge clusters.
Rather than a simple single-host admin panel, OpenFlare empowers traditional OpenResty / Nginx nodes with **centralized cluster orchestration, dynamic zero-reload sync, line-rate edge WAF defense, and secure in-network tunneling**:
* ⚡ **Zero-Reload Dynamic Orchestration**: Centralized control plane manages any number of edge nodes. Synchronize rule diffs in milliseconds with zero Nginx reload disruptions.
* 🛡️ **Built-in Edge Security & Anti-CC (Turnstile Alternative)**: Comprehensive WAF rule engine, MaxMind GeoIP regional ACLs, and **client-side cryptographic Proof of Work (PoW) challenges** to eliminate botnets and CC attacks at line rate.
* 🚇 **Zero-Trust Tunnels (Cloudflare Tunnel Alternative)**: Securely publish private homelab and internal web services to edge proxies via lightweight `openflared` clients without public IPs or open inbound ports.
* 📦 **Pages Edge Hosting**: Host static sites and SPAs pulled directly from GitHub Releases or uploaded bundles, distributed across edge nodes with instant rollbacks and fallback routing.
* 🔒 **Automated Certificates & SSO**: Automatic multi-domain Let's Encrypt certificates via ACME and enterprise single sign-on with GitHub OAuth and standard OIDC.
---
## 🌐 Flexible Deployment: Standalone or Behind Cloudflare
OpenFlare is designed to operate seamlessly either as an independent edge gateway or in harmony with Cloudflare and public CDNs:
### 1. Standalone Edge Gateway (Private CDN)
Ideal for developers managing multi-region VPS clusters or homelabs:
* Deploy your own high-availability CDN and edge proxy cluster with 100% data and privacy ownership.
* Protect origin sites with built-in Turnstile-like PoW human challenges, dynamic WAF, and automated SSL certs without expensive enterprise CDN security plans.
### 2. Behind Cloudflare (Hardened Origin Shield)
Functions as an intelligent **origin shield and routing gateway** behind Cloudflare:
* **Leaked Real IP Protection**: If attackers bypass Cloudflare and directly hit your origin's public IP address, OpenFlare's edge WAF and PoW challenges will immediately intercept and block the attack.
* **Full Private Log & Metric Retention**: Overcomes Cloudflare Free tier limitations by retaining comprehensive, searchable request logs and operational metrics locally.
* **Unified In-Network Routing**: Ingest incoming Cloudflare traffic and dynamically route it across internal backends or private homelab services through secure tunnels.

## 📊 Comparison: Traditional Nginx vs NPM vs OpenFlare
| Feature | Traditional Nginx (`nginx.conf`) | Nginx Proxy Manager (NPM) | **OpenFlare** |
| :--- | :--- | :--- | :--- |
| **Cluster Architecture** | Manual per-host editing via SSH | Single node only; no cluster sync | **Native Distributed Control Plane + Edge Agents** |
| **Configuration Sync** | Requires `nginx -s reload` (connection churn) | Reloads on every change | **Shared memory dynamic sync (Zero-Reload)** |
| **Anti-CC / Bot Protection** | Basic `limit_req` rate limiting only | Not supported | **Built-in Turnstile-like PoW Client Challenge** |
| **In-Network Tunnels** | Requires separate third-party tools (frp) | Not supported | **Built-in OpenFlared Tunnels (Zero inbound ports)** |
| **WAF & Threat Defense** | Requires manual ModSecurity compilation | Basic exploit rules only | **Dynamic WAF, GeoIP, IP list checksum sync** |
| **Static Pages Hosting** | Manual directory copying and setup | Static file proxying only | **Automated GitHub Release deployment & rollbacks** |
| **Works with Cloudflare** | Manual `set_real_ip_from` list maintenance | Complex proxy header tuning | **Native real IP restoration, ideal origin shield** |

## ⚡ Quick Start
### 1. Launch OpenFlare Server
Deploy the control plane using `docker-compose`:
```bash
# Download environment template
curl -o .env.example https://raw.githubusercontent.com/Rain-kl/OpenFlare/refs/heads/main/.env.example
cp .env.example .env
```
```yaml
services:
openflare:
image: ghcr.io/rain-kl/openflare:latest
restart: unless-stopped
env_file: .env
environment:
TZ: ${TZ:-Asia/Shanghai}
ports:
- "3000:3000"
volumes:
- openflare_uploads:/app/uploads
depends_on:
postgres:
condition: service_healthy
redis:
condition: service_healthy
postgres:
image: postgres:17-alpine
restart: unless-stopped
environment:
POSTGRES_DB: ${DB_NAME:-openflare}
POSTGRES_USER: ${DB_USERNAME:-openflare}
POSTGRES_PASSWORD: ${DB_PASSWORD:-replace-with-strong-password}
volumes:
- openflare_postgres_data:/var/lib/postgresql/data
healthcheck:
test: ["CMD-SHELL", "pg_isready -U ${DB_USERNAME:-openflare} -d ${DB_NAME:-openflare}"]
interval: 10s
timeout: 5s
retries: 5
redis:
image: valkey/valkey:8.0-alpine
restart: unless-stopped
command: ["valkey-server", "--appendonly", "yes"]
volumes:
- openflare_redis_data:/data
healthcheck:
test: ["CMD", "valkey-cli", "ping"]
interval: 10s
timeout: 5s
retries: 5
start_period: 5s
volumes:
openflare_uploads:
openflare_postgres_data:
openflare_redis_data:
```
* **Dashboard URL**: `http://localhost:3000`
* **Default Credentials**: `admin` / `12345678`
> [!WARNING]
> Change the default password `12345678` immediately upon first login.
> The BETA version is in active development and testing; avoid using it in mission-critical production environments without regular backups.
### 2. Connect Edge Agent Node
Run the Agent container on any edge server (ensure ports 80/443 are open):
```bash
docker pull ghcr.io/rain-kl/openflare-agent:latest
docker run -d --name openflare-agent --restart unless-stopped \
-p 80:80 -p 443:443/tcp -p 443:443/udp \
-v openflare-agent-pages:/data/var/lib/openflare/pages \
-e OPENFLARE_SERVER_URL=http://<YOUR_SERVER_IP>:3000 \
-e OPENFLARE_AGENT_TOKEN=<YOUR_AGENT_TOKEN> \
ghcr.io/rain-kl/openflare-agent:latest
```
*(Copy the node token directly from Node Management in the dashboard)*
