Jackett vs Nebula: at a glance
What is Jackett?
Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.
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.

5.0INFRA · APIS
Jackett ships a daily build to keep hundreds of torrent indexers working as sites move and close.
◆ Current state
Jackett is an open-source proxy that turns hundreds of torrent tracker sites into a single Torznab API for media automation tools. It ships an auto-generated release roughly every day, and nearly every one is indexer upkeep: new domains, category mappings, selector fixes after site redesigns, and removing dead trackers.
◆ Where it's heading
The work is maintenance that keeps the indexer list current as sites change. Core library bumps arrive alongside it every week or so.
◆ Prediction
Expect daily builds to continue with more additions and removals; no feature change is signalled.
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.
