Public TCP proxies are moving to paid plans. On the free tier you'll still see the option in the public networking config, but it now sits behind an upgrade prompt. For existing applications with TCP proxies, there is no migration to do. These will continue to work and won't be torn down. The change will only apply to creating new TCP proxies. Those on Pro and Enterprise plans are unaffected.
Public TCP proxies are a power-user capability: most legitimate free projects never reach for them, yet we were seeing them frequently for users who were running antagonistic workflows. Gating them to paid plans keeps the free tier focused on trying Suga out and lets us keep it generous for everyone using it as intended.
If you have a legitimate reason for trying out TCP proxies you can reach out to us at support@suga.app and we can arrange a trial.
