I tried migrating our organization from Twingate to self-hosted Netbird for cost savings but couldn't get it working reliably for 10-15% of users. The client failed intermittently with no clear pattern to troubleshoot. It became very frustrating for our end users. My advice: if you're considering self-hosted Netbird, set clear expectations that it's best-effort QoS, not enterprise-grade reliability. There's no such thing as a cheap VPN.
