README
Drip
Your Tunnel, Your Domain, Anywhere
A self-hosted tunneling solution to securely expose your services to the internet.
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.
Why Drip?
- 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
Recent Changes
2025-02-14
- 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
2025-01-29
- Bearer Token Authentication - Added bearer token authentication support for tunnel access control
- Code Optimization - Refactored large modules into smaller, focused components for better maintainability
