Nebula vs RabbitMQ
A side-by-side editorial comparison of Nebula and RabbitMQ — release velocity, themes, recent moves, and the top alternatives to consider.
Nebula vs RabbitMQ: at a glance
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.
What is RabbitMQ?
RabbitMQ 4.4 moves to Erlang 28 and tightens OpenID Connect checks, with 4.3 still patched.
RabbitMQ shipped 4.4.0 on October 28 with full Erlang 28 support and stricter OpenID Connect discovery validation that can break setups with non-compliant identity providers. The 4.3 line keeps receiving maintenance releases: 4.3.6 in September fixed exchange deletion leaving behind bindings that pointed to it, quorum queue membership reconciliation adding too many replicas, and double-counted message store references in classic queue recovery; 4.3.7 followed in October.

Nebula
2.5INFRA · APIS
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.
RabbitMQ
5.0INFRA · APIS
RabbitMQ 4.4 moves to Erlang 28 and tightens OpenID Connect checks, with 4.3 still patched.
◆ Current state
RabbitMQ shipped 4.4.0 on October 28 with full Erlang 28 support and stricter OpenID Connect discovery validation that can break setups with non-compliant identity providers. The 4.3 line keeps receiving maintenance releases: 4.3.6 in September fixed exchange deletion leaving behind bindings that pointed to it, quorum queue membership reconciliation adding too many replicas, and double-counted message store references in classic queue recovery; 4.3.7 followed in October.
◆ Where it's heading
Feature work has moved to 4.4 while 4.3 absorbs correctness fixes, many in quorum queues and cleanup paths. The stricter OIDC validation in 4.4 continues the security tightening seen in 4.3.5's encrypted management login tokens.
◆ Prediction
Expect 4.4.x patches, likely including fixes for identity providers caught by the stricter OIDC checks, alongside further 4.3.x maintenance.
