A self-hosted tunneling solution to securely expose your services to the internet.

Documentation | 中文文档

Drip is a quiet, disciplined tunnel. You light a small lamp on your network, and it carries that light outward—through your own infrastructure, on your own terms.

• Control your data - No third-party servers, traffic stays between your client and server
• No limits - Unlimited tunnels, bandwidth, and requests
• Actually free - Use your own domain, no paid tiers or feature restrictions
• Open source - BSD 3-Clause License

• Bandwidth Limiting (QoS) - Per-tunnel bandwidth control with token bucket algorithm, server enforces min(client, server) as effective limit
• Transport Protocol Control - Support independent configuration for service domain and tunnel domain

# Client: limit to 1MB/s
drip http 3000 --bandwidth 1M

# Server: global limit (config.yaml)
bandwidth: 10M
burst_multiplier: 2.5

• Bearer Token Authentication - Added bearer token authentication support for tunnel access control
• Code Optimization - Refactored large modules into smaller, focused components for better maintainability

bash <(curl -sL https://driptunnel.app/install.sh)

# Configure (first time only)
drip config init

# Expose local HTTP server
