Frequently Asked Questions

Why do URLs expire after 3 hours? ▼
This is a security feature by design. Temporary URLs prevent accidental long-term exposure of your local development environment. Think of it like this: you're sharing your localhost for a demo, debugging session, or webhook testing—not hosting a production site. The 3-hour limit ensures that if you forget to close the tunnel, it automatically disconnects. This protects you from accidentally leaving your local server exposed to the internet indefinitely. Plus, it encourages best practices: use tunnels for temporary testing, not permanent hosting.
Is my traffic encrypted? ▼
Yes. All tunnels run over SSH with end-to-end encryption. No plaintext data is ever exposed. Your connection is as secure as any SSH session.
What ports are supported? ▼
Any TCP port you're running locally. Common examples: 3000 (React), 5173 (Vite), 8000 (Django/Laravel), 8080 (general), or any custom port between 1-65535.
Do I need to open inbound firewall ports? ▼
No. Your machine initiates the SSH connection out to port 443. As long as you can reach the Internet on 443 (HTTPS), you're good. No router configuration needed.
Can I use this in CI/CD? ▼
Yes. The SSH command is non-interactive and scriptable, making it perfect for CI/CD pipelines, automated testing, and ephemeral preview URLs. Great for running integration tests with external services.
Is it free? ▼
xpos.dev is currently free to use with 3-hour session limits. Future plans may include paid tiers for extended sessions and custom domains.
Does HTTPS work on the public URL? ▼
Yes. All public URLs are served over HTTPS with valid TLS certificates automatically managed by the edge. Your visitors see a green padlock.
