Forwarding a single local port through an existing tunneling library is a bounded, achievable integration for personal use. Running a reliable, secure public tunneling service at scale is real networking infrastructure.

Two real costs, not just "free": the AI agent's own usage, and hosting once it's running. Both are estimated from this app's own effort rating and component list — see the assumptions on the method page.
| AI agent — with a subscription (Claude Pro/Max, Cursor, etc.) | $0 marginal |
| AI agent — pay-per-use API, no subscription | $43–$86 one-time |
| Hosting, once it's running | $0/mo (free tier) |
| Domain name, if you want your own | ~$12/yr |
ngrok costs $8/mo. Even paying per-token with no subscription, and accounting for hosting, this build pays for itself in about 11 months.

Borderline. Forwarding a single local port through an existing tunneling library is a bounded, achievable integration for personal use. Running a reliable, secure public tunneling service at scale is real networking infrastructure.
ngrok costs $8/mo (about $96/yr) as of 2026-08. That's what a working rebuild would save you.
Running your own public-facing tunnel relay server reliably, for other people to depend on, is genuine networking and security infrastructure Custom domains and TLS certificate management at scale add real, ongoing operational complexity Protecting a public tunnel from abuse (someone using your relay for something malicious) is a real, ongoing security concern
Yes — localtunnel are open-source options worth trying before you build your own. Details are in the standard parts section on this page.
