Good alternative to xvpn?

Hi there! I was wondering if there are any open source alternatives to xvpn. The reason why? Beacuase xvpn is the only vpn ive found so far that gets past my schools firewall, any other vpns either dont start or error out. Also im a broke teen so if there are any free ones out that’d be great!
Thanks!

Mullvad VPN with ShadowSocks https://mullvad.net/en/help/shadowsocks-android/

Mullvad or Mozilla’s VPN (literally just mullvad but mozilla-fied)

Late but PotatoVPN is an alternative, but it sometimes randomly disconnects and can be slow at times. Other times it runs like normal. Switched to x vpn and instantly better.
