SimpleTunnel gives you instant HTTP/HTTPS and TCP tunnels with TLS encryption and native Kubernetes support. Expose your entire stack - web apps, APIs, databases - securely through one tunnel.
# Expose single port
$ simpletunnel -port 3000
Tunnel established!
HTTP URL: https://nova-4823.simpletunnel.com
# Expose entire stack with multi-port (NEW!)
$ simpletunnel --domain myapp --ports "web:3000,api:8080,db:5432:tcp"
đ Web: https://myapp.simpletunnel.com
đ API: https://myapp.simpletunnel.com/api
đī¸ DB: myapp.simpletunnel.com:10007Everything is working and ready to use today
Automatic SSL certificates via Let's Encrypt. Your tunnels are secure from the moment they're created.
Just run one command. No signup, no API keys, no complex setup. It just works.
Written in Go with automatic reconnection, health checks, and monitoring. Reliable for production use.
Not just HTTP! Tunnel SSH, databases, game servers, or any TCP service through our infrastructure.
Full controller with Helm chart, Docker images, and CRDs. Expose any service with a simple annotation.
Bring your own domain (example.com). Full root domain support included.
Full bidirectional WebSocket support for real-time applications. Works with Streamlit, Jupyter, Socket.io, and more.
Secure your tunnels with HTTP Basic Authentication. Perfect for sharing sensitive development work.
Expose your entire stack (frontend, backend, database) through ONE tunnel with intelligent routing. Use the --ports flag to expose multiple services simultaneously.
Real-time bidirectional communication for modern applications
Full support for Streamlit's real-time updates and interactive widgets.
streamlit run app.py
simpletunnel -port 8501
Interactive notebooks work perfectly with cell execution and live updates.
jupyter notebook
simpletunnel -port 8888
Build chat apps with Socket.io or any WebSocket library.
node chat-server.js
simpletunnel -port 3000
Works with ws:// and wss:// (secure WebSockets)
Bidirectional streaming with frame-level forwarding
Automatically handles Upgrade headers
No special flags needed - it just works!
Pro Tip: WebSocket support is included in all plans, even the free tier! Perfect for testing real-time features during development.
Production-ready controller for automatic service exposure
Expose any service with just one annotation:
simpletunnel.com/expose: "true"
Deploy with one command:
helm install simpletunnel ./chart
Pre-built images on Docker Hub:
apiVersion: v1
kind: Service
metadata:
name: my-app
annotations:
simpletunnel.com/expose: "true" # Enable tunneling
simpletunnel.com/domain: "example.com" # Your domain
simpletunnel.com/use-root: "true" # Use root domain
simpletunnel.com/protocol: "http" # or "tcp"
spec:
selector:
app: my-app
ports:
- port: 80
# This will expose your service at https://example.com
# Without use-root: "true", it would use a random subdomain
# like https://nova-4823.simpletunnel.comExpose your entire development stack with one command
# Terminal 1
ngrok http 3000 # Frontend
# Terminal 2
ngrok http 8080 # Backend API
# Terminal 3
ngrok tcp 5432 # Database
â 3 separate tunnels, 3 different URLs to manage# One command exposes everything
$ simpletunnel --domain myapp --ports "web:3000,api:8080,db:5432:tcp"

Tunnel established!
đ Web: https://myapp.simpletunnel.com
đ API: https://myapp.simpletunnel.com/api
đī¸ DB: myapp.simpletunnel.com:10007
â 1 tunnel, intelligent routing to all servicesAutomatically routes requests based on URL path. /api goes to your backend, / goes to your frontend.
Combine HTTP and TCP services in one tunnel. Perfect for microservices with databases.
Routing happens automatically. No complex config files or manual setup required.
# Expose React frontend, Django API, PostgreSQL, and Redis
$ simpletunnel --domain devstack \
--ports "web:3000,api:8000,db:5432:tcp,cache:6379:tcp"
Result - Full paths are preserved:
https://devstack.simpletunnel.com/ â localhost:3000/
https://devstack.simpletunnel.com/api/users â localhost:8000/api/users
https://devstack.simpletunnel.com/api/v1/products â localhost:8000/api/v1/products
devstack.simpletunnel.com:10007 â localhost:5432 (PostgreSQL)
devstack.simpletunnel.com:10008 â localhost:6379 (Redis)đ Pro Tip: Multi-port tunneling is perfect for demos, webhook testing, and microservices development. Share one URL with your team instead of juggling multiple tunnel endpoints.
Three simple steps to expose your local service
Start your local web server, API, database, or any TCP service on any port.
npm run dev # Port 3000
Run SimpleTunnel with your port number. Get instant HTTP and HTTPS URLs.
simpletunnel -port 3000
Your service is now accessible from anywhere with a secure HTTPS URL.
