GitLab vs Nebula
A side-by-side editorial comparison of GitLab and Nebula — release velocity, themes, recent moves, and the top alternatives to consider.
GitLab vs Nebula: at a glance
What is GitLab?
GitLab is turning its platform into the context layer agents and security teams query, not just a code host.
GitLab's recent output centers on Orbit, now generally available, which links code, merge requests, pipelines, security findings and ownership in one queryable graph. The pitch runs on two tracks: agents get platform context instead of guessing from diffs, and security teams get vulnerability blast radius from a single query. Around that, GitLab is publishing remediation playbooks for third-party CVEs and positioning on regulatory themes like EU sovereignty.
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.

GitLab is turning its platform into the context layer agents and security teams query, not just a code host.
◆ Current state
GitLab's recent output centers on Orbit, now generally available, which links code, merge requests, pipelines, security findings and ownership in one queryable graph. The pitch runs on two tracks: agents get platform context instead of guessing from diffs, and security teams get vulnerability blast radius from a single query. Around that, GitLab is publishing remediation playbooks for third-party CVEs and positioning on regulatory themes like EU sovereignty.
◆ Where it's heading
The direction is clear: GitLab wants the data it already holds about the software lifecycle to be the input every agent, including outside ones, depends on. Duo Agent Platform is stretching beyond the IDE into business systems, and governance features are being framed around supervising agent activity. Security is the lead use case for selling that context.
◆ Prediction
Expect Orbit to surface inside more Duo agents and security workflows, likely with remediation steps that act on the blast-radius answers it returns. The sovereignty post hints at deployment and data-residency messaging, but the entries don't show a concrete product move there yet.

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.
