| Egress | 2GB bandwidth/month on Free; the docs add Anonymous Mode at 100 MB and 30 minutes.; ingress: http-only free_allowance: 2GB bandwidth/month on Free; the docs add Anonymous Mode at 100 MB and 30 minutes. |
| Identity | email An API key from portal.stunl.com. The docs say: Free tier with no credit card required. Anonymous mode needs no key at all. |
| Limits | |
| Binding | volume-quota 2 GB is 0.0018 TiB, so the monthly allowance is spent in about an hour of 1 TiB/month traffic; the 1-hour session cap binds even earlier on a long transfer. |
| Interface | cli, rest stunl -port 3000 -id myapp; API key from portal.stunl.com. |
| Tooling | brew install stunl/tap/stunl or stunl.com/install.sh; stunl.yaml config file. |
| Composes with | Hosts an MCP or webhook endpoint on a free VM; for UDP it requires the $10 plan, which is cheaper than most VPS options but still a bill. |
| Reliability | Free tunnels expire after an hour; anonymous tunnels after 30 minutes and 100 MB. |
| Notes | The service markets itself at AI agents and MCP servers, which explains the HTTP-first free tier. UDP exists but is two tiers above free. |
| Evidence rung | documented UDP on Pro is documented but not tested; a Pro trial run would confirm the UDP listener is a real raw port rather than a WebSocket frame. |
