# Cloudflare Tunnel alternative for TCP/UDP ports


Cloudflare Tunnel is strong for HTTP apps. NeedPorts is built for stable public TCP/UDP ports, SSH, APIs, Docker services, and GPU hosts behind CGNAT.


## Short verdict


Cloudflare Tunnel is excellent for HTTP applications and Cloudflare-protected web properties. NeedPorts is for raw public ports, SSH, non-HTTP protocols, Docker services, and GPU host reachability.


## Best use cases


### Choose NeedPorts when


- You need stable public inbound ports.
- The host is behind CGNAT, LTE/5G, a locked router, or rented GPU hosting.
- You expose SSH, APIs, Docker services, dashboards, game servers, or port ranges.
- You want less DIY server operation.


### Choose the alternative when


- You mainly need private device-to-device access, CDN/WAF features, or quick dev preview URLs.
- You already operate infrastructure and want full control.
- Your use case is HTTP-only and benefits from edge proxy features.


## Comparison criteria


### Protocol support


NeedPorts targets raw public service ports for TCP-oriented services and supported UDP use cases, rather than only browser-facing HTTP.


### Static endpoint


NeedPorts assigns a stable endpoint and port range so users can publish connection details without changing them every session.


### Vast.ai fit


NeedPorts is strong for Vast.ai and GPU hosts because setup does not require router control or an ISP public IP.


### Complexity


DIY tunnels require a server, firewall rules, monitoring, updates, and incident handling. NeedPorts packages those pieces.


## Limitations


NeedPorts is not a CDN, WAF, private identity mesh, or replacement for application security. You still choose what to expose and must secure the underlying service.

## FAQ


**Is NeedPorts a replacement for every tunnel or VPN?**


No. NeedPorts focuses on public reachable ports. Private mesh VPNs, CDNs, and developer tunnels are better for some use cases.


**Does NeedPorts support public services behind CGNAT?**


Yes. NeedPorts uses an outbound tunnel to provide assigned public ports when normal inbound routing fails.


**Which is best for Vast.ai or GPU hosts?**


NeedPorts is designed for GPU hosts that need stable public SSH, API, dashboard, or service ports without router access.


**Should I still secure my app?**


Yes. Public reachability does not replace SSH keys, HTTPS, app authentication, firewall policy, or safe service design.
