Nautobot vs Nebula
A side-by-side editorial comparison of Nautobot and Nebula — release velocity, themes, recent moves, and the top alternatives to consider.
Nautobot vs Nebula: at a glance
What is Nautobot?
Nautobot 3.3 alpha adds API rate limits while 3.2.9 stops cross-user token reads.
Nautobot's 3.2 and 2.4 lines still ship same-day security releases every two weeks. On November 9, v3.2.9 and v2.4.46 fixed a flaw where the Export Object List job let users read other users' API token keys, and closed three more ways to read fields marked sensitive. The same day v3.3.0a1 opened the next feature line with REST API rate limiting, JSON and YAML exports, primary IPs that need no interface, and a breaking change to IP assignments.
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.

Nautobot
5.0INFRA · APIS
Nautobot 3.3 alpha adds API rate limits while 3.2.9 stops cross-user token reads.
◆ Current state
Nautobot's 3.2 and 2.4 lines still ship same-day security releases every two weeks. On November 9, v3.2.9 and v2.4.46 fixed a flaw where the Export Object List job let users read other users' API token keys, and closed three more ways to read fields marked sensitive. The same day v3.3.0a1 opened the next feature line with REST API rate limiting, JSON and YAML exports, primary IPs that need no interface, and a breaking change to IP assignments.
◆ Where it's heading
Since September the work has been a permissions and template-sandbox audit, with each release closing gaps the previous one exposed. 3.3 is the first feature line since then, and its headline additions (rate limiting, timing headers, job duration summaries, export field control) come from running Nautobot at scale and through its API.
◆ Prediction
Expect more 3.3 alphas and betas while the 3.2 and 2.4 lines keep receiving paired security releases; the sensitive-fields controls added in 3.2.5 will likely keep generating bypass fixes.
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.
