Nebula vs Routinator: 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 Routinator?
Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default
Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.

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.

5.0INFRA · APIS
Routinator 0.16 will validate ASPA and BGPsec, and run strict, by default
◆ Current state
Routinator is a mature RPKI validator with a slow, release-candidate-gated cadence. After a run of security work, including an external audit's four CVEs in 0.15.2 and resource-exhaustion fixes in 0.15.3, 0.16.0-rc1 changes defaults: ASPA and BGPsec are on, strict validation is on, and the old enable flags become --disable-aspa, --disable-bgpsec and --relaxed. It also adds Resource Signed Checklists (RFC 9323), SLURM v2 with ASPA filtering, and a new repository logging scheme that changes the /status JSON.
◆ Where it's heading
Having spent 2026 hardening the validator, the maintainers are now changing what operators get out of the box. Defaults moving toward ASPA and strictness put newer RPKI object types on equal footing with route origin validation.
◆ Prediction
A final 0.16.0 following one or more release candidates is the likely next step, as with 0.15.0.
