ngrok alternative

ngrok alternative for TCP and UDP

Compare NeedPorts and ngrok for public endpoints, static ports, TCP/UDP support, Vast.ai hosts, Docker services, SSH, APIs, pricing, and complexity.

Short verdict

ngrok is excellent for developer previews, webhook testing, and quick HTTP demos. NeedPorts is built for stable public ports on machines and services that need persistent inbound 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.

Related setup examples

Expose Docker behind CGNAT, expose SSH or an API, and Vast.ai port forwarding.

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.

Ready for a stable public endpoint?

Start with a NeedPorts trial, map one service, and test the public port from another network before depending on it for production traffic.
