SixterFrequently asked questions
Common questions about Sixter — tunnels, deployment, self‑hosting and HTTPS.
What is Sixter?
Sixter is a secure tunneling and deployment platform. It exposes localhost or a private server to the internet with automatic HTTPS and custom domains, and it can also build, run and deploy your projects.
How is Sixter different from ngrok?
ngrok is a hosted tunneling service. Sixter also tunnels localhost, but adds one‑click project deployment, free custom domains with automatic HTTPS, a built‑in WAF firewall, team coworkspaces, and it can be self‑hosted. See the full Sixter vs ngrok comparison.
Is Sixter self‑hostable?
Yes. The gateway and repo server run on your own VPS, so you control the infrastructure.
Do I need a public IP?
No. In Tunnel Mode your server opens an outbound connection to the gateway, which forwards traffic back down the tunnel. No public IP or port‑forwarding needed.
Can I use my own domain?
Yes. Point a CNAME (or A record for apex) at Sixter and TLS certificates are issued and renewed automatically.
Does Sixter provide HTTPS automatically?
Yes. TLS is terminated at the gateway with automatic certificate management, so tunnels and custom domains are served over HTTPS.
Can a team deploy together?
Yes. Developers sixter push to stage a pending version; a lead or deployment member runs sixter project deploy to promote it. See Team coworkspaces.
