Which plan is right for you?
Free plan
Perfect for students, hobby projects, and getting started with tunneling. You get one active tunnel with full HTTP, TCP, and UDP support, choose any available subdomain (e.g., myapp.fxtun.dev), and work with zero limits on requests, bandwidth, or session duration. The Free plan never expires — use it for testing webhooks, demoing a local project to a client, or debugging payment gateway integrations without any time pressure.
Starter — $2.50/mo
The sweet spot for freelancers, indie developers, and small integration projects. Three active tunnels let you expose a frontend, backend, and webhook receiver simultaneously. One reserved subdomain guarantees a stable URL for demos — no other user can claim your address. A custom domain and the traffic inspector for real-time HTTP request analysis round out the package, all for $2.50 per month.
Base — $5/mo
Built for small teams and developers juggling multiple projects. Five active tunnels, five reserved subdomains, and five access keys mean each team member gets their own key. The built-in traffic inspector lets you view, filter, and replay HTTP requests, replacing manual log analysis when debugging APIs and webhooks. Attach your own domain for a professional-looking demo environment.
Pro — $7.50/mo
The top tier for agencies, dev studios, and teams managing large portfolios. 15 tunnels and 15 reserved subdomains cover the needs of even the busiest shops. Five custom domains for different clients or projects, ten access keys for the whole team. Unlimited traffic inspector, full HTTP, TCP, and UDP support. If your business needs reliable infrastructure for client demos and integration testing, Pro has you covered.
Subdomains: free and reserved
On every plan, including Free, you can pick any available subdomain when creating a tunnel — for example, myapp.fxtun.dev or api-test.fxtun.dev. This is a fundamental difference from ngrok, which assigns a random URL like abc123.ngrok-free.app on its free tier. However, a free subdomain is not locked to your account: once you disconnect the tunnel, another user can claim the same address. Reserved subdomains (starting from the Starter plan) are permanently bound to your account — no one else can use them, even when your tunnel is offline. This is essential for stable demo URLs, third-party service integrations, and webhooks where the address must never change.
What's included in every plan
Every fxTunnel plan, including Free, provides a full set of core capabilities. Support for three protocols — HTTP, TCP, and UDP — lets you expose web apps, SSH servers, game servers, and IoT devices. A desktop application for Windows, macOS, and Linux with a graphical interface, a CLI for automation, and automatic TLS for HTTPS traffic. No limits on request count or bandwidth. No session timeouts — your tunnel stays alive as long as you need it. Auto-reconnect on connection drops: the client restores the session on its own, without manual intervention.
