GLAuth vs Nebula
A side-by-side editorial comparison of GLAuth and Nebula — release velocity, themes, recent moves, and the top alternatives to consider.
GLAuth vs Nebula: at a glance
What is GLAuth?
GLAuth's September releases are security dependency updates and build fixes.
GLAuth's 2.5.0 in April was the substantial release, adding OpenTelemetry tracing, embedded plugins and RISC-V builds. Since then releases have been corrective: disabled users rejected on all backends in 2.5.1, a release-time plugin check in 2.5.2, a port-handling fix in 2.5.3, and 2.5.4 on September 13 updating all dependencies to safe versions.
What is Nebula?
Nebula 1.12 adds optional offloading for throughput after a run of platform fixes.
Nebula is a peer-to-peer mesh VPN with its own certificate authority. Since v1.10.0 added IPv6 and multiple overlay addresses, releases have dealt with the fallout: v1.11.1 fixed an IPv6 firewall bypass, and v1.11.2 in September fixed IPv6 MTU on Windows, local address discovery on Android 11+, and checksums for traffic to a host's own IPv6 address on macOS. v1.12.0 on October 29 added optional UDP and TUN offloading, planned to become the default later, and stricter firewall rule parsing.

GLAuth's September releases are security dependency updates and build fixes.
◆ Current state
GLAuth's 2.5.0 in April was the substantial release, adding OpenTelemetry tracing, embedded plugins and RISC-V builds. Since then releases have been corrective: disabled users rejected on all backends in 2.5.1, a release-time plugin check in 2.5.2, a port-handling fix in 2.5.3, and 2.5.4 on September 13 updating all dependencies to safe versions.
◆ Where it's heading
GLAuth is in maintenance after 2.5.0, with occasional security and build releases. No new features have shipped since April.
◆ Prediction
Expect occasional 2.5.x security updates; the entries give no sign of the next feature release.

Nebula 1.12 adds optional offloading for throughput after a run of platform fixes.
◆ Current state
Nebula is a peer-to-peer mesh VPN with its own certificate authority. Since v1.10.0 added IPv6 and multiple overlay addresses, releases have dealt with the fallout: v1.11.1 fixed an IPv6 firewall bypass, and v1.11.2 in September fixed IPv6 MTU on Windows, local address discovery on Android 11+, and checksums for traffic to a host's own IPv6 address on macOS. v1.12.0 on October 29 added optional UDP and TUN offloading, planned to become the default later, and stricter firewall rule parsing.
◆ Where it's heading
The IPv6 work has moved from security fixes to per-platform correctness, and 1.12 turns to throughput. Offloading starting as opt-in, with a stated plan to make it default, sets up the next release cycle.
◆ Prediction
Expect 1.12.x patches for offloading edge cases, and a later release that turns offloading on by default as announced.
