OpenFlare is an open-source CDN orchestration and edge security platform. It supports reverse proxies, centralized configuration synchronization, secure intranet penetration (Tunnels), dynamic WAF protection, and anti-CC challenges.

After logging in for the first time with the root user, make sure to change the default password 123456.

The BETA version is a temporary product for the development and testing phase. It may contain unknown issues and should not be used in production environments.

Core Features

Reverse Proxy Management: Website rules as the aggregation boundary, supporting multi-domain binding and multi-upstream load balancing with unified management of all OpenResty node configurations.
Immutable Config Version Control: Full-snapshot publish model based on version numbers (YYYYMMDD-NNN), with pre-publish diff preview, a single globally active version, and one-click sub-second rollback.
Secure Intranet Penetration (Tunnels): An open-source alternative to Cloudflare Tunnels. Securely expose local intranet Web services to the public network via Relay and OpenFlared clients — no public IP or open inbound ports required.
Edge WAF Safety Protection: Provides global and custom rule groups, supporting manual/automatic/subscription IP groups, MaxMind GeoIP country-level access control, Checksum-based differential IP group sync (no Nginx reload), and custom block responses.
Anti-CC & Human-Machine Challenge (PoW): Built-in high-performance client-side cryptographic Proof of Work challenges (similar to Turnstile) to block and intercept botnets and scrapers at the gateway edge in seconds.
Pages Static Hosting: Upload pre-built ZIP packages directly; edge Agents pull and serve them via local OpenResty, with SPA Fallback and built-in API reverse proxy configuration.
Automated TLS Certificate Management: Supports dynamic certificate upload, automatic multi-domain certificate matching and binding, and ACME-based automatic issuance and renewal via Let's Encrypt.
Uptime Kuma Monitoring Sync: Integrates with Uptime Kuma to automatically sync the monitoring site list using differential updates, providing real-time awareness of node availability and service health.
SSO Single Sign-On: Supports GitHub OAuth and standard OIDC protocol for seamless integration with enterprise identity providers.
Unified Observability: Aggregates node request metrics, real-time access log details, host/Nginx resource snapshots, health events, and a re-upload buffer for network fluctuations.

Quick Start

1. Launch Server

services:
  postgres:
    image: postgres:17-alpine
    restart: unless-stopped
    environment:
      POSTGRES_DB: openflare
      POSTGRES_USER: openflare
      POSTGRES_PASSWORD: replace-with-strong-password
    volumes:
      - postgres-data:/var/lib/postgresql/data
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U openflare -d openflare"]
      interval: 10s
      timeout: 5s
      retries: 5

  openflare:
    image: ghcr.io/rain-kl/openflare:latest
    restart: unless-stopped
    depends_on:
      postgres:
        condition: service_healthy
    ports:
      - "3000:3000"
    environment:
      SESSION_SECRET: replace-with-random-string
      DSN: postgres://openflare:replace-with-strong-password@postgres:5432/openflare?sslmode=disable
      GIN_MODE: release
      LOG_LEVEL: info

volumes:
  postgres-data:

docker compose up -d

Access at: http://localhost:3000

Default credentials:

Username: root
Password: 123456

2. Install Agent

Before installing an Agent, please install OpenResty on the target node first, or use the Agent Docker image with OpenResty built-in.

You can copy the installation command from Node Management -> Details -> Node Info -> Node Token & Deployment in the control panel, or directly use the scripts below:

Docker Deployment

For Docker deployment, you can directly run the Agent image:

docker pull ghcr.io/rain-kl/openflare-agent:latest
docker rm -f openflare-agent 2>/dev/null || true
docker run -d --name openflare-agent --restart unless-stopped \
  -p 80:80 -p 443:443/tcp -p 443:443/udp \
  -e OPENFLARE_SERVER_URL=http://your-server:3000 \
  -e OPENFLARE_AGENT_TOKEN=YOUR_AGENT_TOKEN \
  ghcr.io/rain-kl/openflare-agent:latest

Local Installation

Using discovery_token to register:

curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
  --server-url http://your-server:3000 \
  --discovery-token YOUR_DISCOVERY_TOKEN

Using node-specific agent_token:

curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/install-agent.sh | bash -s -- \
  --server-url http://your-server:3000 \
  --agent-token YOUR_AGENT_TOKEN

The installation script defaults to /opt/openflare-agent, creates a openflare-agent.service, automatically searches for openresty, and can be executed repeatedly to reinstall or upgrade the Agent.

3. Uninstall Agent

To completely uninstall the Agent and clear local data, run:

curl -fsSL https://raw.githubusercontent.com/Rain-kl/OpenFlare/main/scripts/uninstall-agent.sh | bash

The uninstallation script will stop and remove the openflare-agent.service, and delete the entire /opt/openflare-agent directory. It will not delete the local OpenResty installation.

4. Publish Your First Configuration

Log in to the management panel and add a reverse proxy rule.
View the preview or change summary before publishing.
Activate the new version.
Agents will receive the configuration and apply it via WebSocket notification or subsequent heartbeats.

The version number format is fixed as YYYYMMDD-NNN. Historical versions are immutable, and rollback is achieved by reactivating an older version.
