Gate Project is a VPN service platform that I wrote from scratch. It utilizes OpenConnect as server/client and use certificate as authentication methods.
The project’s website: http://www.gate-project.com
The service is featured as below:

2. One certificate can be logged into all servers.
3. Multi geography servers.
4. Cheap price.
5. Unlimited bandwidth within reason
6. Auto re-issue certificates when payment is done.
7. Support nearly all platforms (Windows, Mac, Linux, Android, iOS)
Feel free to buy 1 day of service and decide later.
