With pinggy.io you can share your Ollama API from localhost with just a single command. Replace the port 11434 with the port where Ollama is running.
Ollama checks the Host header on incoming requests and rejects anything that is not localhost, so the command rewrites it back with u:Host:localhost:11434.
Pinggy will give you a URL like https://ranlkfsbjkxry.a.pinggy.link. Use it as the base URL in any client that speaks the Ollama API.
