Nebula vs OctoPrint: 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 OctoPrint?
OctoPrint 2.0 is on its seventh release candidate, still with no final date.
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.

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.
OctoPrint
5.0INFRA · APIS
OctoPrint 2.0 is on its seventh release candidate, still with no final date.
◆ Current state
OctoPrint 2.0 makes serial one connector among several, including Moonraker and Bambu, and removes deprecated plugin APIs. Release candidates have arrived every few weeks since April: rc5 in August fixed config and schema regressions, and rc6 and rc7 in October carried only the standard warning that a candidate may need a manual downgrade.
◆ Where it's heading
The 2.0 line is in a long stabilisation, with each candidate fixing regressions and asking testers to cover the new connectors. The thin notes on rc6 and rc7 suggest the remaining changes are small.
◆ Prediction
A 2.0.0 final is likely within a few candidates; the exact date is unclear from the entries.
