FAQ
What's the difference between self-hosted and hosted?
Self-hosted means you run the NullBore server on your own infrastructure. You get all features, no limits, no cost — but you manage the server. Hosted means we run the infrastructure for you. You get a URL, dashboard, and API key instantly.
What kind of URL do I get?
On the free plan, you get a random URL like a7f3bc.tunnel.nullbore.com. On Hobby, you can choose a name like heroapp.tunnel.nullbore.com — first come, first served, tied to your account. On Pro, you can bring your own domain.
Can I use NullBore with AI agents and MCP servers?
Yes — it's one of our best use cases. Expose a local MCP server to a cloud-hosted agent temporarily, run your workflow, and the tunnel closes automatically. Works great with OpenClaw and other agent frameworks.
Can I upgrade or downgrade anytime?
Yes. Changes take effect immediately. Downgrades prorate to the next billing cycle.
What happens when a tunnel's TTL expires?
The tunnel closes automatically. The public URL stops working. On the Hobby plan, you can enable auto-renew to keep tunnels alive up to 7 days. Pro plan tunnels can run indefinitely — they stay up until you close them.
What counts as bandwidth?
All data relayed through the tunnel — both directions. If you're proxying a 1MB page load, that's ~1MB of bandwidth.
Do you log tunnel traffic?
No. We track metadata (byte counts, request counts, timestamps) but never inspect or log payload content.
Can I use NullBore for webhook testing?
Absolutely — expose a local endpoint temporarily, point Stripe/GitHub/etc at it, test your integration, done.
